The aircraft returned to Chicago for a safe landing on runway 10C about 25 minutes after stopping the climb. A replacement ERJ-145 registration N687JS reached Cleveland with a delay of 2:15 hours. The airline reported the aircraft experienced a mechanical issue with the windscreen. http://avherald.com/h?article=4df8caae&opt=0 Incident: Republic E170 near Philadelphia on Nov 21st 2020, lost both bleed valves A Republic Airways Embraer ERJ-170 on behalf of Delta Airlines, registration N873RW performing flight DL-5646 from New York La Guardia to Nashville,TN (USA), was climbing out of New York when the crew stopped the climb at FL250 and subsequently performed an emergency descent to 10,000 feet due to the loss of cabin pressure. The crew advised they had a bleed air valve issue losing both bleeds, no further assistance was needed. The aircraft diverted to Philadelphia for a safe landing on runway 27L about 40 minutes after leaving FL250. A replacement ERJ-175 registration N201JQ reached Nashville with a delay of 5:15 hours. The occurrence aircraft is still on the ground in Philadelphia about 15 hours after landing. https://flightaware.com/live/flight/RPA5646/history/20201121/2010Z/KLGA/KBNA http://avherald.com/h?article=4df8c797&opt=0 Incident: Starflyer A320 at Fukuoka on Nov 20th 2020, engine trouble A Starflyer Airbus A320-200, registration JA21MC performing flight 7G-42 from Fukuoka to Tokyo Haneda (Japan) with 104 people on board, was climbing through FL310 out of Fukuoka when the left engine (CFM56) lost power prompting the crew to stop the climb, drift down to FL240 and return to Fukuoka for a safe landing on runway 36 about 75 minutes after departure. The flight was cancelled, the passengers were rebooked onto other flights. http://avherald.com/h?article=4df7904a&opt=0 Incident: Delta A319 at Austin on Nov 19th 2020, smoke in cabin A Delta Airlines Airbus A319-100, registration N330NB performing flight DL-1062 from Austin,TX to Seattle,WA (USA) with 29 people on board, had just levelled off at FL360 out of Austin when the crew reported light smoke in the cabin and decided to return to Austin. The aircraft landed safely on Austin's runway 17R about 55 minutes after departure. The flight was cancelled, the passengers were rebooked onto other flights. https://flightaware.com/live/flight/DAL1062/history/20201119/1210Z/KAUS/KSEA http://avherald.com/h?article=4df6e01b&opt=0 Photo: NTSB NTSB: No obvious cause of fatal 2019 air ambulance crash Federal investigators say they’re baffled over what caused an air ambulance over Southeast Alaska to rapidly plunge into the water in January of last year, killing all three aboard. The recovery of the Guardian Flight’s voice recorder failed to capture the flight’s final moments that might have explained what caused the fatal crash about 22 miles west of Kake. Audio recorded nearly two years ago by air traffic control the evening the Guardian flight disappeared sheds no new information on what caused the fatal crash. It was released by the National Transportation Safety Board on Wednesday as part of its factual report. Pilot Patrick Coyle is heard preparing to land the King Air 200 in Kake to pick up a patient. NTSB’s chief investigator Clint Johnson says everything in those final moments are routine as the pilot moved to make his approach on January 29, 2019. “There’s no indications of any problems before before he’s he switched over to basically a local frequency that announces his intentions,” he told CoastAlaska on Thursday. Then something went terribly wrong. Flight data logged by radar shows the twin-engine Beechcraft suddenly veered to the right at about 6:10 p.m. “Has medevac N13LY checked with you at all? Looks like was a little bit low,” an air traffic controller is heard saying. “And then, unfortunately, at the end of the recording is when they started looking for him,” Johnson said. Investigators later determined that the plane dropped about 2,575 feet in 14 seconds. An intense search for wreckage followed around Frederick Sound. Initially, the Coast Guard sent a cutter after its Sitka-based helicopters were grounded with a maintenance problem — and later, a helicopter from Air Station Kodiak arrived. But it’s unlikely that the delay in the air search made any difference. The Guardian plane was heavily damaged and had sunk in deep water. “The only reason we were able to find the wreckage in the 500 to 600 feet (of water) was because of the acoustical pinger that was attached to the cockpit voice recorder — so that was at least one win,” Johnson said. “However, once we recovered that cockpit voice recorder, we sent it to our vehicle recorder lab in Washington, DC, they noted that unfortunately, the cockpit voice recorder must have stopped working sometime back in 2015.” A cockpit voice recorder captures pilot interactions that are not radioed to air traffic control — in a 30-minute loop. But not in this case. After drying and cleaning the unit, all investigators discovered was a recording of a May 15, 2015 flight into Fort Yukon. Investigators were able to pinpoint that date because the crew was listening to Game 6 of the NBA playoffs. An announcer gave the score of Golden State Warriors leading the Memphis Grizzlies 58-49 at halftime. There was no useful information on the recorder beyond that day. After recovering pieces of the aircraft, investigators didn’t find any mechanical faults. The only thing out of the ordinary was that the three crew seats recovered were unbuckled. Investigators aren’t speculating over what significance that could have. The NTSB found there appears to have been a sudden and unexplained loss of control that, Johnson says, led the Guardian Flight air ambulance to crash into the water at high speed. “Beyond that, we really don’t know,” Johnson said. “Unfortunately, every road that we took every lead that we got ran pretty much to a dead end.” The bodies of 63-year-old pilot Patrick Coyle; 43-year-old paramedic Margaret Langston and 30-year-old nurse Stacie Rae Morse were never found. Morse was more than six months pregnant when the plane crashed. The loss of the three-member air ambulance crew was a tragedy felt in Alaska’s medical community, especially Juneau where they lived. A company spokesman wrote in a statement that Guardian Flight went to great lengths to try and recover the missing crew member’s bodies. “We await the Final Report from the NTSB with the results of its analysis, findings, and probable cause of this accident, which is expected in a number of months,” wrote Guardian spokesman Jim Gregory on Thursday. NTSB’s Clint Johnson says the mystery of the cause of the crash has been frustrating for the air ambulance company, the crew member’s family and friends and for federal investigators seeking answers or lessons learned. https://www.alaskapublic.org/2020/11/19/ntsb-no-obvious-cause-of-fatal-2019-air-ambulance-crash/ Europe, Canada, Brazil have additional requirements to unground 737 MAX The U.S. FAA lifted the grounding of the Boeing 737 MAX on November 18. In the days that followed, other regulators stated that they will not fully follow the FAA requirements. EASA stated that “sufficient reason exists to require certain additional actions, deemed necessary to ensure safe operation of the affected aeroplanes, including pilot training.” A proposed AD will be published for public consultation. Transport Canada stated: “These differences will include additional procedures on the flight deck and pre-flight, as well as differences in training.” Brazilian regulator ANAC reported: “ANAC recognizes the decision of the FAA and works on final adjustments of the validation process for returning the model to the country.” https://news.aviation-safety.net/2020/11/22/europe-canada-brazil-have-additional-requirements-to-unground-737-max/ Boeing 737 MAX jets undergo round-the-clock effort to clear inventory MOSES LAKE, Wash. (Reuters) - The future of Boeing Co's freshly approved 737 MAX is in the hands of nearly 700 workers toiling behind the gray doors of a three-bay hangar at a desert airport in Washington state. Inside, over an endless 24-hour loop, 737 MAX planes are rolled in for maintenance, and upgrades of software and systems as mandated by the U.S. Federal Aviation Administration in this week's order lifting a flight ban imposed after two crashes, the airport's director said. In front, workers in bright yellow vests inspect the roughly 240 jets stored in giant grids at Grant County International Airport in Moses Lake - more than half of an inventory worth about $16 billion, according to investment firm Jefferies. Analysts say clearing the logjam of up to 450 stored jets in total is crucial before Boeing can resume meaningful production of its traditional cash cow - a task complicated by the fact that buyers have in some cases walked away during the grounding. While parked on the tarmac, each jet is fitted with red engine and wheel covers, a windshield screen to block out the sun, and a small generator powering cycles of fresh air and electricity through its systems - the aviation equivalent of life support. "It's an enormous undertaking," the airport's director, Rich Muller, told Reuters. "But this go-ahead from the FAA has given them a real shot in the arm. It's really energized everyone." The work at Moses Lake is a cornerstone of a global logistical and financial strategy under way at Boeing to clear a backlog of more than 800 mothballed 737 MAX jets. About 450 are Boeing property, and a further 387 were in airline service before the FAA's grounding order in March 2019. Across the globe, Boeing teams are hammering out delivery schedules - and financial terms - with airlines who last year had to scale back schedules and fly aging jetliners because they lacked the aircraft to meet strong demand as the MAX grounding dragged on longer than airline and Boeing executives expected. But the jet is returning at a time when the coronavirus pandemic has hammered demand for air travel and new jets. Boeing also faces new European trade tariffs and palpable mistrust of one of the most scrutinized brands in aviation. "Airlines and the supply chain do not see major deliveries until 2022," said Arndt Schoenemann, managing director of supplier Liebherr-Aerospace Lindenberg. "Right now, COVID is the biggest problem for the industry." A Boeing spokesman declined to comment beyond listing preparation steps before 737 MAXs go to customers, which include installing a flight control software upgrade to deal with a system tied to both crashes, separating wiring bundles that posed a potential safety hazard, and multiple tests including a test flight before a final FAA inspection. WHITE TAILS Airlines say it will take about two weeks to ready each plane for service with maintenance and software upgrades factored in, though Boeing has already deployed teams around the world to help companies get ready. In a visual display of the jet demand slump, workers at Moses Lake on Thursday rolled a 737 MAX "white tail" - a jet without a buyer, or whose buyer has been changed - out of a long row of aircraft awash in the bright liveries of airline customers, ranging from customers American Airlines to Norwegian Air. This week, Norwegian sought bankruptcy protection in Ireland. Reuters counted 12 white tails at Moses Lake on Thursday, though sources say Boeing is worried about 100 such aircraft in inventory, or more. Boeing declined to comment. Jets are also stored at Boeing property in the Seattle area and in San Antonio, Texas. Boeing is in discussions with several airlines, including Southwest, Delta and Alaska, hoping to stimulate demand for the jet. Deals are expected to include significant discounts, industry sources have said. But analysts caution cutting prices too far could upset other customers. A fire sale could also depress resale values of such single-aisle jets - the cornerstone of a complex system of financing that has attracted capital to the industry, powered by relatively strong returns on planes which are seen as mobile real estate. To kickstart the recovery of the MAX and contain any fallout to the jet's valuation while offering aggressive discounts to find new homes, Boeing is expected to line up a handful of large deals with marquee customers who will put them in long service. The 737 MAX 8 has a list price of $122 million but the market long ago abandoned published prices as competition heated up. Most jets are privately sold well over 50% below the list price and the new MAX discount may be more, jet traders said. Slowing the recovery, the FAA, which has faced accusations of being too close to Boeing in the past, has said it plans in-person inspections of each of the 450 planes, which could take at least a year to complete, prolonging the jets' deliveries. Grant County International has been a strategically important asset for Boeing at least since the 1960s, and every MAX built in the Seattle area is flown there for touch-and-go landings or other tests. The airport and abutting Boeing property has absorbed nearly 700 employees and contractors to aid the ungrounding effort, up from only a handful, Muller said. Meanwhile, Boeing is paying some $51,000 per plane a month to park its MAXs, he added. https://www.yahoo.com/finance/news/boeing-737-max-jets-undergo-120539627.html European regulator to lift Boeing 737 MAX grounding in January PARIS (Reuters) - Europe is set to lift its flight ban on the Boeing 737 MAX passenger jetliner in January after U.S. regulators last week ended a 20-month grounding triggered by two fatal crashes. The head of the European Union Aviation Safety Agency (EASA) said in remarks aired on Saturday that the 737 MAX was safe to fly after changes to the design of the jet that crashed twice in five months in 2018 and 2019, killing 346 people. “We wanted to carry out a totally independent analysis of the safety of this aircraft, so we performed our own checks and flight tests,” Executive Director Patrick Ky told the Paris Air Forum, an online aviation conference hosted by La Tribune. “All these studies tell us that the 737 MAX can return to service. We have started to put in place all the measures,” he said. “It is likely that in our case we will adopt the decisions, allowing it to return to service, some time in January.” EASA’s decision is seen as the most important milestone after the FAA’s approval since, as the watchdog responsible for Airbus, it too carries significant weight in the industry. Officials confirmed a draft EASA directive proposing to end the grounding in Europe will be published next week, followed by a 30-day comment period. After finishing touches, that would lead to an ungrounding decision in January. How long it takes for flights to resume in Europe depends on pilot training and the amount of time it takes airlines to upgrade software and carry out other actions mandated by EASA. In the United States, commercial flights are scheduled to start on Dec. 29, just under six weeks after the FAA order was published on Nov 18. EASA represents the 27 European Union countries plus four other nations including Norway, which has 92 of the aircraft on order. Until Dec 31, it also represents the United Kingdom, which left the EU bloc in January. FAA LESSONS The crashes in Indonesia and Ethiopia triggered a slew of investigations faulting Boeing for poor design and the FAA for lax oversight. They also placed tight-knit FAA relations with Boeing under scrutiny. “It is clear that there were a number of dysfunctions in (FAA) actions and their relations with Boeing,” Ky said. “I won’t go into details as it is not up to me to do that. The FAA is in the process of putting in place corrective measures.” He said EASA would change some of its own methods and take a more detailed role in analysing critical features in foreign jets. It would also be “more intransigent” about ensuring that key safety reviews are completed before moving on to the next steps, Ky said. Until now, one primary regulator certifies a plane and others mainly follow suit after varying degrees of independent checks. “What will change is the way in which we validate and certify Boeing aircraft, that’s clear, but will it have an impact on (certification) timings? No, I don’t think so; we will do things differently,” Ky said. Boeing is developing the 777X, a larger version of its 777. EASA is widely seen as emerging strengthened from the Boeing crisis and some regulators are waiting for its decisions on the MAX rather than immediately following the FAA as in the past. FAA chief Steve Dickson played down any differences last week, saying there was “very little daylight” between regulators and that the FAA worked closely with Europe, Canada and Brazil. https://www.reuters.com/article/us-boeing-737max-easa/european-regulator-to-lift-boeing-737-max-grounding-in-january-idUSKBN2810KU Wyvern Awards Sun Air First 'Flight Leader' Certificate California-based charter operator Sun Air Jets has achieved Wyvern’s first Flight Leader certificate, which the aviation safety risk management firm said is a step above its Wingman certification and focuses less on regular auditing and more on SMS effectiveness, as well as human factors and organizational culture. “It requires discipline and professionalism to become a Wingman, and it takes sound leadership and effective management of human and organizational factors to be a Flight Leader,” said Wyvern CEO Sonnie Bates. “A Flight Leader inspires other Wingman operators to reach higher and attain new levels of excellence.” According to Wyvern, Flight Leader focuses on continual soft-skills training and monitoring of safety performance indicators related to human and organizational factors, through quarterly self-assessments and recommendations for the achievement of 90-day goals. In the past 12 months, a number of operators have joined the program and Wyvern expects additional Flight Leader certificates to be issued in the coming weeks. “Sun Air Jets takes great pride in being the first operator to receive this distinctive award and we are grateful to Wyvern for the opportunity,” said Sun Air safety director and v-p of business strategy Andreas Mauritzson. “We feel that it is essential to continue to put safety as our utmost priority.” https://www.ainonline.com/aviation-news/business-aviation/2020-11-19/wyvern-awards-sun-air-first-flight-leader-certificate Greece Wants F-35s So Quickly It’s Willing to Accept Used Aircraft Greece has formally asked the U.S. to purchase 18-24 F-35s, and it wants them so quickly it’s willing to accept ex-USAF airplanes, according to Pentagon officials and Greek press reports. The official Letter of Request was transmitted to the Pentagon by the Greek defense ministry on Nov. 6. The request asks for the “immediate” purchase of aircraft, such that the first ones could be delivered in 2021; the document said this timeline is “crucial.” While it’s not clear why Greece views the timing of the purchase as so critical, industry officials said it likely has to do with European Union loan guarantees that will expire in the coming months. The financing is also viewed as the reason Greece may be willing to accept used, ex-Air Force F-35s. The LOR said the sale would be affected by the speed of delivery, configuration of the aircraft, and “the repayment plan.” Greece has publicly indicated a desire to buy F-35s since early 2019, but ongoing fiscal problems prevented a formal request. The Greek defense ministry initially said it was contemplating the purchase of 25-30 F-35s. A defense official, speaking on background, said the Air Force has “not identified any F-35s that are excess to need,” so it’s not certain that there are any aircraft that could be made available for sale to Greece secondhand. However, the Air Force has wrestled in recent years with whether it wants to spend the money to modify its oldest training F-35s up to the current production standard. Selling the older jets and replacing them with newer models might meet the Air Force’s needs. USAF has indicated, however, that it will use some older F-35s as Aggressor aircraft. Defense officials said the U.S. has urged Greece to buy the F-16V Block 70, the most advanced version of the F-16 now available for export. With an extensive F-16 support enterprise already in place, Greece could easily absorb that airplane at a much lower cost, but one official said there’s “a prestige factor” involved. A small batch of F-35s could also be a “force multiplier” for Greece’s other F-16s, he observed. Turkey, an original partner on the F-35, has been drummed out of the program by the U.S. and NATO allies because of Turkey’s insistence on ordering and deploying the Russian S-400 air defense system. Industry officials speculated that F-35s completed for Turkey–but not delivered–could be offered to Greece. While the U.S. Air Force is getting some of those aircraft, others could be made available for Greece. “You could think of them as ‘pre-owned,’ but not necessarily ‘used,’” a defense official said. If Greece is permitted to order brand-new F-35s, it would have to get in line: Lockheed Martin’s production capacity is spoken for through at least 2024, an industry official reported. The request to buy the F-35 follows Greece’s recent order of Rafale fighters from France. That sale includes six new aircraft and 12 previously flown by the French air force. France has indicated it will replace the 12 airplanes with new-build examples. The first Rafales are set to be delivered to Greece early next year. The F-35s and Rafales would buttress a fleet of some 154 F-16s already serving in the Hellenic Air Force. While the bulk of those aircraft—about 84 airplanes—are of the Block 52 configuration, about 70 are older Block 30 and 40 models. In 2018, Lockheed Martin received a nearly $1 billion contract, along with partner Hellenic Aerospace Industries, to upgrade Greece’s F-16s with an array of new gear by 2027. https://www.airforcemag.com/greece-wants-f-35s-so-quickly-its-willing-to-accept-used-aircraft/ Etihad Tells Pilots to Move into Cheaper Company Accommodation or Face Being Axed Etihad Airways has told pilots to move into smaller company-provided accommodation close to its headquarters near Abu Dhabi International Airport or face being sacked according to internal company sources who claim to be familiar with the matter. The latest cost-cutting move comes nearly two weeks after the heavily indebted airline warned pilots of more imminent job losses in the face of a slower than expected recovery from the COVID-19 pandemic. Like many airlines in the Middle East, Etihad provides accommodation for most of its workers including cabin crew and pilots. Most employees live in shared apartments with the majority of bills covered by the airline but pilots are afforded the opportunity to live in accommodation of their choosing with rent and bills heavily subsidised. Sources claim pilots have now been given an ultimatum to move into apartments within Etihad Plaza, part of the airline’s head office. Pilots who decline the move will reportedly have their contracts terminated. As of February 2020, Etihad employed 1,969 pilots although the airline has not updated these figures since Coronavirus related lay-offs were initiated. Etihad has declined to say exactly how many pilots it has made redundant since February but the airline’s chief executive Tony Douglas has admitted that “thousands” of employees have been laid-off. Sources claim a further 240 foreign expat pilots were made jobless in the last couple of weeks, along with a further 680 cabin crew. Last week, the airline told staffers that it had “indefinitely” grounded its fleet of 10 Airbus A380s citing a slower than expected recovery in the demand for air travel. Unlike neighbouring Dubai, the emirate of Abu Dhabi is still shut to international tourists and a resurgence of COVID-19 in Europe, the United States and elsewhere is continuing to pummel demand. Douglas told reporters last month that no decision had yet been made whether to scrap the A380’s but a spokesperson for the airline said the double-deck aircraft would remain grounded unless demand increased sufficiently. Etihad has confirmed plans to significantly downsize the airline, labelling itself as a mid-sized carrier. The company has already jettisoned some of its senior management team in an attempt to reduce costs, while further cabin crew redundancies are expected early next year. Cabin crew on older, better-paid contracts are expected to be firing line. A spokesperson for Etihad said the airline does “not comment on rumour or speculation”. https://www.paddleyourownkanoo.com/2020/11/22/etihad-tells-pilots-to-move-into-cheaper-company-accommodation-or-face-being-axed/ China to launch moon probe, seeking first lunar rock retrieval since 1970s BEIJING (Reuters) - China plans to launch an unmanned spacecraft to the moon this week to bring back lunar rocks in the first attempt by any nation to retrieve samples from Earth's natural satellite since the 1970s. The Chang'e-5 probe, named after the ancient Chinese goddess of the moon, will seek to collect material that can help scientists understand more about the moon's origins and formation. The mission will test China's ability to remotely acquire samples from space, ahead of more complex missions. If successful, the mission will make China only the third country to have retrieved lunar samples, following the United States and the Soviet Union decades ago. Since the Soviet Union crash-landed the Luna 2 on the moon in 1959, the first human-made object to reach another celestial body, a handful of other countries including Japan and India have launched moon missions. In the Apollo programme, which first put men on the moon, the United States landed 12 astronauts over six flights from 1969 to 1972, bringing back 382 kg (842 pounds) of rocks and soil. The Soviet Union deployed three successful robotic sample return missions in the 1970s. The last, the Luna 24, retrieved 170.1 grams (6 ounces) of samples in 1976 from Mare Crisium, or "Sea of Crises". China's probe, scheduled to launch in coming days, will attempt to collect 2 kg (4 1/2 pounds) of samples in a previously unvisited area in a massive lava plain known as Oceanus Procellarum, or "Ocean of Storms". "The Apollo-Luna sample zone of the moon, while critical to our understanding, was undertaken in an area that comprises far less than half the lunar surface," said James Head, a planetary scientist at Brown University. Subsequent data from orbital remote sensing missions have shown a wider diversity of rock types, mineralogies and ages than represented in the Apollo-Luna sample collections, he said. "Lunar scientists have been advocating for robotic sample return missions to these many different critical areas in order to address a host of fundamental questions remaining from earlier exploration," Head said. The Chang'e-5 mission may help answer questions such as how long the moon remained volcanically active in its interior and when its magnetic field - key to protecting any form of life from the sun's radiation - dissipated. THE MISSION Once in the moon's orbit, the probe will aim to deploy a pair of vehicles to the surface: a lander will drill into the ground, then transfer its soil and rock samples to an ascender that will lift off and dock with an orbiting module. If this is successful, the samples will be transferred to a return capsule that will return them to Earth. China made its first lunar landing in 2013. In January 2019, the Chang'e-4 probe touched down on the far side of the moon, the first by any nation's space probe. Within the next decade, China plans to establish a robotic base station to conduct unmanned exploration in the south polar region. It is to be developed through the Chang'e-6,7 and 8 missions through the 2020s and expanded through the 2030s ahead of manned landings. China plans to retrieve samples from Mars by 2030. In July, China launched an unmanned probe to Mars in its first independent mission to another planet. https://www.yahoo.com/finance/news/china-launch-moon-probe-seeking-043042985.html RTCA Free Technical Webinar 11/30: Interference Risk on Radar Altimeters from Planned 5G Telecommunication Systems Join RTCA and leaders of Special Committee 239 (SC-239) for a discussion on the planned 5G telecommunications system implementation that could interfere with radar altimeters.
