Boeing issues advice over sensors after Indonesia crash

Boeing issues advice over sensors after Indonesia crash

Indonesian investigators said their flight procedure recommendations to Boeing were based on how the flight crew responded to problems on the Bali to Jakarta flight.

The AD followed Boeing's issuing of an operations manual bulletin (OMB), asking 737 MAX operators to remind pilots of how to handle "erroneous" information from the aircraft's angle of attack sensors.

The official said that if the condition is not addressed, it could cause the flight crew to have difficulty in controlling the airplane.

On Tuesday, in the wake of the Lion Air crash in Indonesia - where 189 people were killed - the plane maker sent a bulletin that warns incorrect readings from a flight-monitoring system can result in the jets abruptly diving.

Virgin has ordered 30 of the fuel-efficient 737 Max 8 aircraft, which are due for delivery in November 2019, and will replace its existing 737-700/800 planes.

A plane owned by low-priced Indonesian airline Lion Air has torn a wing on a runway in Indonesia just days after one of its flights crashed into the Java Sea, leaving 189 dead.

"An investigation will be carried out by Aircraft Inspection and Airworthiness Inspector, Airport Inspector and Aviation Navigation Inspector to see the cause of the incident and the appropriate follow-up steps", Acting Director General of Air Transportation M Pramintohadi Sukarno said.

Soerjanto Tjahjono, chairman of the transport safety committee, said Wednesday that airspeed indicator malfunctions on the jet's last four flights, which were revealed by analysis of the flight data recorder, were intertwined with the sensor issue.

"This is all coming from the Indonesian crash", said the person briefed on the Boeing bulletin.

Boeing issues an operational update for 737.

'The investigation into Lion Air flight 610 is ongoing and Boeing continues to co-operate fully and provide technical assistance at the request and under the direction of government authorities investigating the accident, ' Boeing said. It's still possible the FAA may order the Chicago-based planemaker to redesign the equipment or software as investigators piece together details of the October 29 accident, which killed 189 people. Erroneous readings from the AOA sensor could push the plane into an aggressive, unwarranted dive.

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

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

Pilots can counteract this for up to 10 seconds at a time by pushing a switch on the airplane's controls.
