Boeing to Issue Alert Its Planes Can Abruptly Dive During Flight - Report

Exhibiting similar problems, a recently delivered Lion Air Boeing 737 Max 8 passenger plane crashed into the sea off Jakarta, Indonesia nearly two weeks ago with 189 people onboard.

Boeing said in a statement received at China's largest air show in Zhuhai that its bulletin to airlines underscored "existing flight crew procedures" created to address circumstances where information coming into the cockpit from the sensors was wrong.

The US Federal Aviation Administration issued an emergency airworthiness directive on how to handle erroneous data from a sensor that investigators believe malfunctioned on a new Boeing jet that plunged into the sea in Indonesia, killing all 189 people on board.

Boeing's newly issued bulletin focuses on the 737 MAX's angle-of-attack sensors, or AOA sensors, which are supposed to provide data about the angle at which wind is passing over the airplane's wings. If the flow is disrupted by a plane going too slowly or climbing too steeply, that can cause the plane to lose the lift required for flight and plummet.

United said: "We are in receipt of a Flight Crew Operations Manual Bulletin, issued by Boeing, which applies to the 16 737 Max 8 aircraft now in our fleet".

"But it is quite straightforward and we train for this all the time", the captain said.

Boeing has sent 219 737 MAX jets to customers globally, with 4,564 orders for jets yet to be delivered.

However, Bloomberg wrote that the pilots in the Lion Air crash reported an "erroneous airspeed indication" after taking off from Jakarta airport and before they slammed into the water at around 966km per hour, according to Indonesia's National Transportation Safety Committee.

Boeing issues an operational update for 737.

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.

The DGCA had reviewed the performance of Boeing 737 MAX 8 planes operated by Jet Airways and SpiceJet.

A source said on condition of anonymity that the Boeing bulletin related only to the 737 MAX, of which there are just over 200 in service.

Problems were reported on a Lion Air jet that crashed into the sea off Jakarta even after technicians replaced a sensor on board the aircraft, investigators said.

"When there was a problem, the pilot would write it down and the mechanic would do (a repair).Then the plane would be declared airworthy".

Visitors watch as a Boeing 737 Max lands after an air display during the Farnborough Airshow, southwest of London, on July 16, 2018. They are now combing the seas for the voice recorder.
