Indonesia's National Transportation Safety Committee (NTSC) said it had agreed with Boeing on procedures that the airplane manufacturer should distribute globally on how flight crews can deal with "angle of attack" sensor problems following the October 29 crash that killed all 189 people on board.
The left wing of the Lion Air Boeing 737-900 plane collided with the metal post as the aircraft was heading to the runway at the Fatmawati airport in Bengkulu, Indonesia.
Boeing has issued a warning to airlines using the company's 737 MAX that some models may issue "erroneous data" to pilots that could cause the plane to nosedive.
CBS News reported on Wednesday that Boeing's 737 Max 8 planes are used across the US, including by Southwest Airlines, American Airlines and United Airlines. Under some circumstances, such as when pilots are manually flying, the Max jets will automatically try to push down the nose if they detect that an aerodynamic stall is possible, the person said.
The issue only occurs when a plane's autopilot is switched off, Boeing said. "We continue to monitor all developments and will respond accordingly to any recommendations that enhance safety".
US aviation regulators said they are drafting an order requiring that airlines follow Boeing's instructions.
More than a week ago, a Lion Air plane crashed into the sea 15 minutes after taking off from Jakarta.
"This is a tragedy, but (the safety bulletin) says absolutely nothing about the design of the plane and its major subsystems", TEAL Group aviation analyst Richard Aboulafia told Business Insider. It is believed the plane plunged at over 600mph, but the cause of the accident is still under investigation.Читайте также: Pixel 3 memory management issue to be fixed soon
Safety investigators said that pilots on the plane were dealing with inaccurate airspeed readings and asked to return to the airport just before the crash.
On Tuesday, Indonesian investigators found that the Lion Air flight had a malfunctioning air speed indicator for its last four flights and crucially, at the time of the crash.
This affects almost 250 aircraft flown by U.S. airlines like Southwest, American and United, the FAA said.
He said the pilot had landed the plane safely on that occasion.
American said it was issuing similar communications to its pilots to emphasize the existing protocols.
The Indonesian Ministry of Transportation has begun an audit of Lion Air (JT, Jakarta Soekarno-Hatta) and has also started impromptu checks of various other Indonesian carriers following the crash of one of the low-priced carrier's B737-8s on October 29.
Meanwhile, the search operation to recover the passengers, crew and the airplane's cockpit voice recorder is ongoing.При любом использовании материалов сайта и дочерних проектов, гиперссылка на обязательна.
