The crew returned the aircraft to Bamako for a safe landing. A post flight inspection revealed a cargo net had entangled with the door locks. http://avherald.com/h?article=4e08bc0b&opt=0 Incident: Eurowings A319 at London on Dec 14th 2020, smoke in cabin An Eurowings Airbus A319-100, registration D-ABGQ performing flight EW-9463 from London Heathrow,EN (UK) to Dusseldorf (Germany), was climbing through FL120 out of Heathrow's runway 27L when the crew stopped the climb, donned their oxygen masks reporting smoke in the cabin and decided to return to Heathrow. The crew advised ATC they wanted to vacate the runway and stop on the adjacent taxiway to have emergency services check the aircraft for any smoke in and outside of the cabin. The aircraft landed safely on Heathrow's runway 27R about 15 minutes after departure, vacated the runway via taxiway A6 and stopped immediately after crossing the hold short line. Emergency services inspected the aircraft. The passengers disembarked onto the taxiway, were taken to the terminal and rebooked onto other flights. http://avherald.com/h?article=4e08c27e&opt=0 FBI: At least 5 pilots report drone flying near Charlotte Douglas flight path CHARLOTTE, N.C. — The FBI is looking for whoever has been illegally flying a drone recently near a flight path to Charlotte Douglas International Airport. According to the FBI, there have been at least five reports by commercial airline pilots of a drone flying at least 4,000 feet in the air between Oct. 30 and Dec. 8. Officials said it has been happening in the Fort Mill area. In 2018, the Federal Aviation Administration Reauthorization Act criminalized “unsafe operation of unmanned aircraft.” This specifically applies to “knowing or reckless interference or disruption of a manned aircraft, and the operation of unmanned aircraft in close proximity to airports.” While the drone did not come into direct contact with the airplane or cause a pilot to avoid it, the FBI said these actions are illegal and extremely dangerous. Anyone flying a drone near a plane or a flight path can face federal criminal charges, fines and be imprisoned for up to life. Authorities said it is possible the drone operator is not aware they are violating the law. With Christmas around the corner and drones being given and received as gifts, the FBI encouraged the public to follow federal and state laws as it applies to flying drones. https://www.wsoctv.com/news/local/fbi-investigating-drone-flying-near-several-flights-charlotte-douglas-airport/CDQTUMVMABFC3HOJPDJI3HGNCE/ 110 Pakistan International Pilots Licenses Have Now Been Checked In its ongoing bid to solve pilot safety issues, Pakistan International Airlines (PIA) has cleared the licenses of 110 pilots. The carrier said 110 of the 141 suspended pilots have had their licenses checked and can now fly again. However, 29 pilots also saw their licenses canceled or were deemed unfit to fly by the airline. Fake licenses The current probe began in the aftermath of the crash of flight PK8303 in late May. The PIA A320 crashed into a residential area in Karachi after a failed landing attempt. Investigations revealed that possibly hundreds of PIA pilots were either flying on fake licenses or had cheated in the training process. The news of fake licenses quickly prompted the European Union’s aviation regulation, EASA, to ban flights from PIA. The US’s FAA and others also quickly downgraded the carrier’s safety rating in the eyes of this scandal. For its part, PIA has been engaged in a months-long investigation to find corruption and verify its pilot’s licenses. In August, the airline sacked 63 pilots for their fake pilot credentials and fired 54 more for various other issues. Verified This week’s news that PIA has cleared some of its pilots to fly will be a relief to the beleaguered carrier. According to Dawn, lawyers for the airline told the Supreme Court that of the 141 pilots who were suspended at the time, 110 have had their licenses cleared. Verification likely means that these pilots are now considered fit to fly. However, lawyers also informed the court that action had been taken against some more pilots. Flying licenses have been canceled for 15 pilots, while 14 pilots have been declared unfit to fly. A few pilots are still in the review process. Return to Europe? The decision to ban PIA from Europe has had a significant impact on the airline’s bottom line. Countries such as the UK and France are popular destinations from Pakistan, with the ban hurting revenue in an already difficult year. While the original ban from July 1st was only set to last for six months, EASA further extended the ban this month. According to Mint, EASA continues to have concerns over pilot training and safety measures being undertaken by the government while issuing licenses. It’s unknown when PIA could return to EU skies, but the timeline could as long as a few years. While PIA might be banned from flying to the EU, other carriers have leaped at the opportunity to fill the gap. Virgin Atlantic inaugurated its new Manchester-Islamabad service in early December, it’s first Pakistani destination. British Airways has also ramped up operations in the country, adding flights to Lahore, its second destination in the country. https://simpleflying.com/pia-pilots-licenses-checked/ Pfizer Increases Dry Ice Life Span Improving Vaccine Capacity On Boeing Aircraft As the Pfizer vaccine begins being distributed around the world, how are airlines overcoming the issue of dry ice? The answer to that is with some groundbreaking new packaging from Pfizer and some expert advice from planemaker Boeing. The second most exciting thing about the Pfizer vaccine is its packaging While we’re all delighted to see the successful rollout of the Pfizer-BioNTech COVID-19 vaccine beginning to take shape around the world, one of the less glamorous elements of this technological breakthrough is the packaging it is shipped in. Early in the process, Pfizer realized that the vaccine’s temperature requirements would make it a problem to ship, particularly by air, so they did something about it. The pharmaceutical company has reportedly invested $2 billion in its production and logistics solutions, including redeveloping the dry ice packaging. According to Pfizer, “We have developed packaging and storage innovations to be fit for purpose for the range of locations where we believe vaccinations will take place. We have specially designed, temperature-controlled thermal shippers utilizing dry ice to maintain recommended storage temperature conditions of -70°C±10°C for up to 10 days unopened. “ While we don’t know the specifics of the Pfizer packaging, what we do know is that it’s making a huge difference to the ease with which the vaccine will be transported around the world. What’s the issue with dry ice? Dry ice is, in itself, not a dangerous substance. However, how it behaves can be, particularly on an aircraft. It doesn’t melt like regular ice, but instead it sublimates. This causes it to change from a solid into a gas, releasing carbon dioxide (CO2) into the surrounding area. In an enclosed space like an aircraft, this could become hazardous. Prolonged exposure could cause crew and passengers to become confused, or even to fall unconsious. Of course, aircraft have Environmental Control Systems (ECS) that are designed to control CO2, and which can vent these gasses to prevent build up. However, the venting is limited, which means the amount of dry ice being transported must be carefully managed. The key factor to bring into the equation is the rate of sublimation. This rate can be used to calculate how much dry ice can be carried for a certain length of journey. Driving down that rate of sublimation brings up the amount that can be carried, thereby increasing the payload of vaccine on each plane. So good, Boeing had to redraw its charts Whatever Pfizer came up with, it’s working really well. The manufacturer claimed that the packaging it developed for the Pfizer-BioNTech COVID-19 vaccine had driven down the sublimation rate to less than 1% of its weight per hour. Early indications from real-life transportation scenarios suggest Pfizer was right on the money with this figure. Prior to this pressing need to distribute large amounts of supercooled vaccine around the world, most goods shipped using dry ice would struggle to achieve a sublimation rate of anything under 2-3%. To support the aviation industry through this huge logistical challenge, Boeing has been creating reference charts to assist in calculations of maximum dry ice loads. These include aircraft specific guidance, data curves of dry ice loading over time, and information that is useful not just to Boeing operators but also to all aircraft owners worldwide. Traditionally, Boeing’s data curves for dry ice loading went down to 1%. In response to the very low sublimation rates of the Pfizer packaging, Boeing had to extend its charts into the range below 1%. While we can’t share the curves with you at this time, it’s safe to say that the maximum level of transportable vaccine increases exponentially with every fraction of a percent lower sublimation. To illustrate this point, for a typical Boeing 777-300, goods using dry ice with a sublimation rate of 2%, Boeing might calculate the maximum load to be 3200 lbs. At 1%, that would increase to 6400 lbs. At 0.5%, the volume soars to a staggering 12,500 lbs. What Pfizer has done with its groundbreaking packaging is to solve the biggest problem that was presented with vaccine shipment. It could well reshape the transportation of low-temperature goods in the future, making dry ice shipments far easier to handle. https://simpleflying.com/boeing-aircraft-vaccine-capacity-increased/ IATA Renews Call on Governments to Consider Aviation Workers as Essential for Vaccination International Air Transport Association (IATA) The International Air Transport Association (IATA) renewed its call on governments to ensure that employees in the aviation sector are considered as essential workers during the impending COVID-19 vaccine campaign, once health care workers and vulnerable groups have been protected. IATA’s 76th Annual General Meeting (AGM) had unanimously adopted a resolution to this effect. “We are not asking for aviation workers to be on top of the list, but we need governments to ensure that transportation workers are considered as essential when vaccine roll-out plans are developed. The transportation of the COVID-19 vaccines has already begun, and as calculations show, it will require the equivalent of 8,000 Boeing 747 freighter aircraft for global distribution. It is therefore essential that we have the qualified workforce in place to ensure a functioning logistics chain,” said Alexandre de Juniac, IATA’s director general and CEO. IATA’s call is aligned with the proposed Roadmap for Prioritizing Uses of COVID-19 Vaccines by the World Health Organization’s Strategic Advisory Group of Experts on Immunization (SAGE). This recommends priority populations for vaccination based on the respective epidemiologic situation and vaccine supply scenarios. Within this framework, SAGE has included transportation workers alongside other essential sectors outside health and education sectors including police, for example. The AGM also reiterated the vital role of air transport in facilitating the global response to the pandemic, including the timely distribution of medicines, testing kits, protective equipment and eventually vaccines around the world. https://www.aviationpros.com/airlines/press-release/21202611/international-air-transport-association-iata-iata-renews-call-on-governments-to-consider-aviation-workers-as-essential-for-vaccination FAA Publishes AD On Superior Crankshafts Some 257 four-cylinder Superior and Lycoming engines are now subject to a new airworthiness directive requiring crankshaft replacement within 25 hours. A Notice of Proposed Rulemaking was published in February but the new AD goes into effect on Jan. 15, 2021. The engines include Superior’s own IO-360 and O-360s as well as certain Lycoming 360-series models that may have had the crankshaft installed as a replacement part. The AD lists specific serial numbers for the parts, which were delivered between 2012 and 2014. According to the FAA, the AD “was prompted by three crankshaft assembly failures that resulted in the loss of engine power and immediate or emergency landings. The FAA is issuing this AD to prevent failure of the crankshaft assembly. The unsafe condition, if not addressed, could result in failure of the engine, in-flight shutdown, and loss of the airplane.” The accidents happened between March 2017 and October 2018, and all were in training aircraft. The FAA says that crankshaft failures resulted from “residual white layer formation, also known as a compound layer, on certain crankshaft assemblies as a result of improper manufacturing by a third-party vendor.” Superior, however, disputed the FAA’s findings, saying that the cranks had proper material and heat treatment, and that the fatigue fractures noted in the three broken cranks were not consistent with a too-thick “white layer.” “As supported by the reports, the FAA finds that white layer contributed to the early crack initiation and, on all failed crankshaft assemblies, exceeded OEM specifications,” the agency said. Superior also contended that the engines had been subjected to “misuse, abuse, or lack of lubrication,” but the FAA also rejected that argument. Superior has not said what it will do for owners of the affected engines, nor is it clear that replacement crankshafts will be immediately available. In general, engine shops are reporting shortages of certain critical parts due to COVID-19 slowdowns. It’s also worth noting that the AD applies to certified aircraft and not, explicitly, experimental/amateur-built aircraft, which have been touched by the issue. However, most builders are expected to abide by the terms of the AD and seek replacement crankshafts even if they aren’t legally required to. https://www.avweb.com/aviation-news/faa-publishes-ad-on-superior-crankshafts/ Airlines in Line for $17 Billion in Pandemic Relief Proposal By Alan Levin • U.S. carriers continue to struggle with declining passengers • Bill would extend airline payroll subsidies through March Airlines would get $17 billion in U.S. government aid to recall furloughed workers and help cover payrolls through March under a bipartisan pandemic relief package unveiled in Congress on Monday that won immediate backing from an industry group. Airlines “enthusiastically support” the proposal, the trade group Airlines for America said in a press release. Carriers will attempt to bring back workers who have been laid off if it passes, “but that becomes increasingly challenging with each passing day,” the group said. House Speaker Nancy Pelosi asked top congressional leaders in both parties to meet Tuesday afternoon to discuss Covid-19 relief and a crucial government spending package, congressional aides said, in what could be a make-or-break moment for a grand bargain after months of stalemate. The $748 billion bill was put forth by a dozen senators and has the support of 50 House members. Some Democrats in the group suggested voting on the bill even though it doesn’t have a top Democratic priority of state and local aid. Airline shares rose Tuesday following two days of losses, with a Standard & Poor’s index of nine industry stocks climbing 2.1% at 1:56 p.m. in New York. The index had tumbled 30% this year through Monday, while the S&P 500 gained 13%. Carriers are losing more than two-thirds of passengers compared with 2019 levels due to Covid-19 and cut tens of thousands of workers after initial government assistance aimed at paying salaries expired on Oct. 1. Calls to extend the aid from both Republicans and Democrats failed as pre-election partisan disagreements over how to structure a new package led it to founder. Supporters stripped out controversial elements that had held up previous packages in their latest attempt. A summary of the proposal released on Monday said it would extend the previous payroll aid through March 31. An aid package passed a year earlier provided $25 billion for passenger carriers and $3 billion for their subcontractors. That money was to pay for payroll and benefits, and airlines that accepted it had to agree not to cut jobs as well as other concessions. The bill also includes $4 billion in funding for airports, including airport businesses; $8 billion for bus, school transport and ferry industries; $15 billion for public transit systems; and $1 billion for Amtrak. In the original pandemic package, more than $70 billion was allotted for loans and payroll assistance to airlines, airports and related businesses. https://www.bloomberg.com/news/articles/2020-12-15/airlines-stand-to-get-17-billion-in-pandemic-relief-proposal Heathrow Airport wins court backing for third runway LONDON (AP) — Plans for a third runway at London’s Heathrow Airport have been given a new boost after the airport’s owner won a Supreme Court challenge Wednesday. The Appeal Court had blocked the project earlier, ruling that the government failed to take account of its climate commitments when it approved the expansion plans. Heathrow Airport Ltd., which owns and operates the airport, challenged that ruling. The Supreme Court overturned it Wednesday and ruled that the runway plans were lawful. The latest ruling clears a hurdle for Heathrow, but there are still more in the way. Any planning decisions on the project will have to show they are compatible with the government’s commitments to addressing climate change, including its Net Zero commitment to remove almost all carbon emissions from the economy by 2050. The expansion of Heathrow, one of Europe’s busiest airports, has been a controversial project for over a decade. Environmental groups have long campaigned against it, raising concerns including the impact on air quality and noise pollution. Green campaigners said Wednesday’s outcome was “incredibly disappointing” but insisted there “remains real doubt” about whether the third runway will ever happen. Heathrow said the ruling was “the right result for the country." The airport said it has “already committed to net-zero and this ruling recognises the robust planning process that will require us to prove expansion is compliant with the U.K.’s climate change obligations, including the Paris Climate Agreement, before construction can begin.” “Demand for aviation will recover from COVID-19 and the additional capacity at an expanded Heathrow will allow Britain as a sovereign nation to compete for trade and win against our rivals in France and Germany," it added. https://journalstar.com/business/heathrow-airport-wins-court-backing-for-third-runway/article_632d9dde-f579-500f-a437-8d65f237cc03.html British Airways partners with ZeroAvia to speed up the switch to hydrogen-powered passenger aircraft British Airways (BA) has teamed up with ZeroAvia, a leading innovator in decarbonizing commercial aviation (earlier post), in a project to explore how hydrogen-powered aircraft can play a leading role in the future of sustainable flying. The collaboration, which reflects the importance of sustainability at British Airways, will see ZeroAvia embedded in the heart of the airline. The team will work remotely alongside mentors and experts to explore the transformational possibilities of moving from fossil fuels to zero-emission hydrogen to power the airline’s future fleet. In September 2020, ZeroAvia achieved a major technological breakthrough by completing the world’s first hydrogen fuel cell powered flight of a commercial-size aircraft, which took off from Cranfield Airport. The Piper M-class six-seat plane completed taxi, take-off, a full pattern circuit, and landing. The partnership forms part of BA parent IAG’s Hangar 51 accelerator program, which works with start-ups and scale-ups from around the world, providing them with an opportunity to develop and test their products on real world business challenges on a global scale. At the end of the program, research and learnings from the process will be shared and the ZeroAvia and Hangar 51 teams will consider how the partnership will progress longer term. British Airways is committed to a sustainable future and achieving net zero carbon emissions by 2050. In the short-term this means improving our operational efficiency and introducing carbon offset and removal projects, while in the medium to longer term we’re investing in the development of sustainable aviation fuel and looking at how we can help accelerate the growth of new technologies such as zero emissions hydrogen-powered aircraft. —Sean Doyle, CEO of British Airways In 2021, ZeroAvia expects to further demonstrate the credibility of its technology at longer ranges and using larger aircraft. The company expects to achieve the commercialization of hydrogen-electric power for aircraft as early as 2023 with flights of up to 500 miles (805 km) in up to 20-seater aircraft. By 2027, it plans to have powerplants in service capable of powering commercial flights of more than 500 miles in aircraft with up to 100 seats and by 2030 more than 1,000 miles in aircraft with 100+ seats. Both British Airways and ZeroAvia are part of the Jet Zero Council, a partnership between government and industry to drive forward the UK Government’s net zero-emission ambitions for the aviation and aerospace sector. https://www.greencarcongress.com/2020/12/20201215-bah2.html Air Canada latest to forewarn more cash burn; looks to raise C$850 million (Reuters) - Air Canada said on Tuesday it looks to raise about C$850 million ($669.45 million) in a share offering, after it warned of more cash burn in the fourth quarter as spiking COVID-19 cases do more harm to air travel and the airline's liquidity. The airline industry is still losing billions of dollars every month due to weak travel demand, exacerbated by recent coronavirus travel advisories that have discouraged holiday travel. United Airlines, Delta Air Lines and American Airlines also raised their cash burn expectations earlier this month. Air Canada expects average net cash burn of between C$14 million and C$16 million per day in the fourth quarter, compared with its prior estimate of C$12 million to C$14 million. The company said it intends to grant underwriters an option to purchase up to an additional 15% of the shares in the offering, the proceeds of which will be used to bolster working capital. ($1 = 1.2697 Canadian dollars) https://www.yahoo.com/news/air-canada-fears-higher-cash-213025427.html Russia flies first new post-Soviet passenger airliner with domestic engines MOSCOW (Reuters) - Russia flew a new passenger airliner with domestically-built engines for the first time since the Soviet era on Tuesday, the start of what it hopes will be a revival of a civil aviation industry to challenge Boeing and Airbus. The medium-range MC-21 plane took off from a Siberian airfield powered by Russian-built PD-14 turbo-fan engines. The plane first flew in May, 2017, but with U.S.-made engines. The MC-21 is built by Irkut Corporation, part of United Aircraft Corporation (UAC), and the engines are built by United Engine Corporation, all of which are majority owned by Rostec, Russia's state aerospace and defence conglomerate. UAC said the plane carried out a range of flight tests in a maiden voyage that lasted one hour and 25 minutes. The Soviet Union was a major builder of passenger airliners used widely at home and in allied countries. But after the fall of communism, airlines largely retired their fleets of Tupolevs and Ilyushins for Boeings and Airbuses. The Kremlin has been pushing to make Russia less reliant on Western imports, particularly since 2014, when the United States and EU imposed some financial sanctions in response to Russian military intervention in Ukraine. Moscow had planned to begin delivering the MC-21 to buyers in 2019, but that date was pushed back, with Rostec saying U.S. sanctions had forced manufacturers to replace composite materials in the wings with Russian-made equivalents. The first deliveries are now expected at the end of next year. Two modifications of the plane, which can seat 130 to 211 passengers, will be made available for order - one with U.S. Pratt & Whitney PW1400G-JM engines and the other with the PD-14 engines, UAC said. Orders have been placed for 175 of the aircraft, with state carrier Aeroflot accounting for 50, UAC said. It did not say how many would include the Russian-built engines. https://www.yahoo.com/finance/news/russia-flies-first-post-soviet-142952773.html China prepares for return of lunar probe with moon samples BEIJING (AP) — Chinese ground crews are standing by for the return of a lunar probe bringing back the first fresh samples of rock and debris from the moon in more than 40 years. The Chang’e probe is expected to land in the Siziwang district of the vast Inner Mongolia region late Wednesday or early Thursday. It fired its engines early Wednesday to put it on course before the orbiter separates from the return vehicle, with all systems functioning as expected, the China National Space Administration said. Recovery of the return vehicle will be complicated by its small size, darkness and heavy snow, state media reported. Plans call for it to perform an initial bounce off the Earth’s atmosphere to reduce its speed before passing through and floating down on parachutes, making it difficult to precisely calculate where it will land, the official Xinhua News Agency quoted Bian Hancheng, a leader of the recovery crew, as saying. State broadcaster CCTV showed four military helicopters standing by Wednesday morning at a base on the snow-covered grasslands. Crews in vehicles on the ground will also seek to hone in on signals. While sprawling in size, the area is relatively familiar because of its use as a landing site for China’s Shenzhou crewed spaceships. Chang'e 5 set down on the moon on Dec. 1 and collected about 2 kilograms (4.4 pounds) of samples by scooping them from the surface, and by drilling 2 meters (about 6 feet) into the moon’s crust. The samples were deposited in a sealed container that was carried back to the return module by an ascent vehicle. Flying a Chinese flag, the lander ceased functioning soon after it was used as a launching pad for the ascender, which was ejected from the orbiter after transferring the samples and came to rest on the moon’s surface. The spacecraft’s return will mark the first time scientists have obtained fresh samples of lunar rocks since the former Soviet Union’s Luna 24 robot probe in 1976. Chang’e 5 blasted off from a launch base in China's southern island province of Hainan on Nov. 23 on a mission expected to last 23 days. It marks China’s third successful lunar landing but the only one to lift off again from the moon. Its predecessor, Chang’e 4, became the first probe to land on the moon’s little-explored far side and continues to send back data on conditions that could affect a future extended stay by humans on the moon. The moon has been a particular focus of the Chinese space program, which says it plans to land humans there and possibly construct a permanent base. No timeline or other details have been announced. China also has joined the effort to explore Mars. In July, it launched the Tianwen 1 probe, which was carrying a lander and a robot rover to search for water. China’s space program has proceeded more cautiously than the U.S.-Soviet space race of the 1960s, which was marked by fatalities and launch failures. In 2003, China became the third country to send an astronaut into orbit on its own after the Soviet Union and the United States. The latest flight includes collaboration with the European Space Agency, which is helping to monitor the mission. Amid concerns over the Chinese space program’s secrecy and close military connections, the U.S. forbids cooperation between NASA and the CNSA unless Congress gives its approval. That has prevented China from taking part in the International Space Station, something it has sought to compensate for with the launching of an experimental space station and plans to complete a permanent orbiting outpost within the next two years. The rocks and debris brought back by Chang’e 5 are thought to be billions of years younger than those obtained by the U.S. and former Soviet Union, offering new insights into the history of the moon and other bodies in the solar system. They come from a part of the moon known as the Oceanus Procellarum, or Ocean of Storms, near a site called the Mons Rumker that was believed to have been volcanic in ancient times. As with the 382 kilograms (842 pounds) of lunar samples brought back by U.S. astronauts from 1969 to 1972, they will be analyzed for age and composition and likely shared with other countries. https://www.yahoo.com/news/china-prepares-return-lunar-probe-051800724.html 2021 Aircraft Cabin Air Conference Registration Now Open ** With over 500 registrants in just 10 days - the sponsors have extended the free registration to the first 1000 registrants ** 2021 Aircraft Cabin Air Conference 15 to 18 March 2021 1500 to 2000 GMT daily via Zoom (0700 to 1200 PST) Four online days of powerful talks given by industry and subject matter experts.
