“The fact that this aeroplane requires such jury paraphernalia to fly is a red flag,” that captain — who is not identified by name — wrote in a news to a sovereign Aviation Safety Reporting System. The captain added that partial of a plane’s moody complement is “not described in a Flight Manual.”

Records uncover that sovereign aviation authorities perceived during slightest 11 reports concerning a Boeing 737 MAX 8 from veteran aviators logged between Apr 2018 and Dec 2018.

Sunday’s pile-up in Ethiopia followed an Oct. 29, 2018, crash of Lion Air Flight 610, in that 189 passengers and organisation died when it plunged into a Java Sea outward Indonesia. Both flights crashed after experiencing extreme speed fluctuations during ascent, with their pilots perplexing to lapse to ground after takeoff.

Regulators and attention experts suspect that MAX 8’s Maneuvering Characteristics Augmentation System, or MCAS, might have caused a jets to make neglected dives.

Flight information recovered from a Indonesia crash indicated pilots regularly attempted to get a plane’s nose adult before impact. After a crash, Boeing released a use circular warning pilots that erring moody information fed into a MCAS could force a aircraft into a dive for adult to 10 seconds.

Following a pile-up in Ethiopia, a association pronounced it had no new guidance. 

The commander complaints, first reported Tuesday by a Dallas Morning News, emerged as aviation regulators around a universe were hustling to respond to a dual crashes in 5 months.

In one documented complaint, a commander pronounced a plane’s downturn triggered the belligerent vicinity warning system, that is designed to warning pilots when their planes are in evident danger. The censure states an alarm sounded “don’t sink, don’t sink” before a captain away a autopilot and manually practiced a craft to climb.

This week, a European Union, United Kingdom, China, Australia, Ethiopia, Indonesia and Malaysia grounded a MAX 8 over reserve concerns. Airline officials in a United States have so distant resisted vigour to follow suit, nonetheless regulators have concurred that there were reports of identical issues in both cursed flights.

FAA mouthpiece Lynn Lunsford declined to criticism on a specific commander censure reports, that are logged by a Aviation Safety Reporting System. Lunsford remarkable a reports do not plead MCAS, a feature suspected to have played a purpose in both crashes.

Kristy Kiernan, an partner highbrow during Embry-Riddle Aeronautical University’s college of aeronautics in Daytona Beach, Florida, cautioned opposite sketch conclusions from a MAX 8 aircraft censure reports, that she reviewed for USA TODAY.

“There’s zero that unequivocally struck me as a pattern,” Kiernan said. “I only don’t consider there’s anything we can pull from it during all.”

Although a reports involve the MAX 8, a issues are opposite than those flagged about a MCAS complement in a Lion Air crash, Kiernan said. For example, two pilots lifted concerns about issues after engaging a plane’s autopilot, though Kiernan noted that a MCAS system is unattached when a autopilot is incited on. Another of a reports focused on a opposite system, the aircraft’s automobile throttles.

The anonymous reports are submitted by pilots on a intentional basement to constraint reserve concerns and are used by regulators to support policies directed during dwindling a odds of accidents.

Opinion: Why FAA and NTSB are not caving to domestic and open pressure

As aviation regulators around a universe this week dangling a MAX 8, a FAA settled that a “investigation has only begun and to date we have not been supposing information to pull any conclusions or take any actions.”

Boeing has sole scarcely 400 of a airliners, including 74 to domestic carriers, and has taken orders for thousands more. A association orator stressed “full certainty in a safety” of a planes Tuesday.

“The Federal Aviation Administration is not mandating any serve movement during this time, and formed on a information now available, we do not have any basement to emanate new superintendence to operators,” Boeing pronounced in a statement.
