Boeing is said to be warning its 737 Max customers about erroneous cockpit readings that could make the passenger jet ‘aggressively dive’ – Finance

  • Boeing is preparing to send a warning to all the operators that have taken delivery of its new 737 Max aircraft, according to an anonymous source cited by Bloomberg.
  • Exhibiting similar problems, a recently delivered Lion Air Boeing 737 Max 8 passenger plane crashed into the sea off Jakarta, Indonesia almost two weeks ago with 189 people onboard.
  • The warning comes as Indonesia’s transport ministry has scheduled a briefing to share the latest information on the Lion Air tragedy.

Boeing is reportedly preparing a bulletin to all operators of the new 737 model warning that erroneous readings from a flight-monitoring system can cause the planes to aggressively dive, Bloomberg quoted a person familiar with the matter.

Boeing will caution its customers of “erroneous readings” from a flight-monitoring system can cause the planes to abruptly dive, Bloomberg quoted an anonymous source as saying.

Boeing will also warn pilots to follow an existing procedure to handle the problem.

The bulletin is being prepared based on preliminary findings from the crash of one of the planes off the coast of Indonesia, said the person, who asked not to be named discussing the inquiry.

According to a company statement as of September 30, Boeing had 4,783 firm orders from 98 identified customers for the 737 Max.

According to Bloomberg there are over 200 737 Max jets already in use in commercial aviation.

Aviation expert Geoffrey Thomas told Business Insider that Boeing has around 9,000 737s in the sky at any given time.

Representatives of 737 Max operators, Singapore Airlines offshoot SilkAir, Garuda Indonesia and Canada’s WestJet, said they had not yet received a bulletin from Boeing, Reuters reports.

Data from the black box of the Lion Air 737 Max that fell into the sea with 189 people onboard has confirmed there was an issue with the plane’s airspeed indicator.

Soerjanto Tjahjono, the head of Indonesia’s National Transportation Safety Committee, said on Monday that the flight data recorder from the crashed plane shows that the problem occurred in its last four flights, including the fatal flight on October 29.

Without an accurate airspeed reading, planes are at serious risk of crashing. Jets flying too slowly can stall, and ones accelerating too much can tear themselves apart from the force.

A faulty airspeed instrument was a factor in the loss of Air France Flight 447, which crashed into the Atlantic Ocean on its way from Brazil to Paris in 2009.

The Lion Air 737 Max 8 speared into the coastal waters off Java on Oct. 29, just 13 minutes after takeoff.

Bloomberg says the plane’s velocity was uncharacteristically high, possibly touching speeds of 600 miles an hour as it hit the water.

Certainly, Indonesian search and rescue officials had trouble locating the wreck, despite encountering a large amount of wreckage in the four days leading up to the discovery of the fuselage.

Flight JT610 radioed a request to return to Jakarta to land, but never turned back toward the airport, according to Indonesia’s National Transportation Safety Committee.

The committee has said they were dealing with an “erroneous airspeed indication.”

Indonesia’s transport ministry has scheduled a briefing at 12:30 p.m. in Jakarta on Wednesday to share updated information on the Lion Air accident, Bloomberg reports.
