Lion Air jet crash: Search for bodies extended

"The Indonesian National Transportation Safety Committee has indicated that Lion Air flight 610 experienced erroneous input from one of its AOA (Angle of Attack) sensors", Boeing said.

The problem with the planes is in the "angle of attack" sensor which calculates the position of the plane relative to the air current.

The "black box" data recorder from the jet shows its airspeed indicator malfunctioned on its last four flights, investigators said Monday. "Is this fatal? NTSC wants to explore this", he is reported as saying.

"We are formulating, with NTSB and Boeing, detailed inspections regarding the airspeed indicator", he said, referring to the U.S. National Transportation Safety Board.

Aerospace giant Boeing is preparing to alert pilots of its new 737 Max line of passenger jets warning that inaccurate readings in an onboard flight-monitoring system can cause the planes "to abruptly dive", Bloomberg reported on Tuesday, citing a source with knowledge of the matter. If it proves true that the AoA sensor was indeed at fault, the investigation will reveal much about what the pilots knew and suspected when confronted with the situation, what their training was like, and what their responses to the incident not only were, but also should have been.

Flight crews should follow a separate protocol to halt the plane's potentially unsafe action, according to the bulletin. A spokesman for Chicago-based Boeing couldn't immediately be reached for comment. Of course, this is something they already overwhelmingly do, as we can see from the generally incredible recent safety record in global aviation, but clearly something went very wrong here that shouldn't have.

Aircraft and engine manufacturers routinely send bulletins to operators noting safety measures and maintenance actions they should take, majority relatively routine.

US aviation regulators said they are drafting an order requiring that airlines follow Boeing's instructions.

The JT610 flight sped up as it suddenly lost altitude and then vanished from radar just minutes after take-off.

Divers have pulled the plane's flight data recorder from the water, but are still hunting for the cockpit voice recorder- a key device that could provide clues to what caused the nearly brand-new plane to plunge into the sea.

"If there are urgent findings to be delivered, we will convey them to the operators and to the manufacturer", he said.

"Lion Air said the problem was fixed, is it true the problem was cleared?" asked Bambang Sukandar, whose son was on the flight.

The bulletin says: "In the event of erroneous AOA data, the pitch trim system can trim the stabilizer nose down in increments lasting up to 10 seconds".

The Boeing 737 MAX is a more fuel-efficient version of the manufacturer's popular single-aisle jet.

Indonesian officials said on Wednesday they would extend by three days the search for bodies.

Meanwhile, Lion Air Corporate Strategic Communications Danang Mandala Prihantoro said that its company always adheres to the standard operation periodic checks that include pre-flight check, transit check, and post-flight check which determines an aircraft's "safe to fly" status prior to taking off.

Last Monday's crash is the worst airline disaster to happen in Indonesia since 1997 when 234 people died on a Garuda flight.
