The U.S. planemaker said investigators probing the Lion Air crash off the coast of Indonesia, in which all 189 on board were killed, had found that one of the "angle of attack" sensors on the brand-new Boeing 737 MAX jet had provided erroneous data.
"Data from the black box showed that the two flights before Denpasar-Jakarta also experienced the same problem".
The new details revealing an air speed indicator problem - gleaned from a recovered flight data recorder - come after the government said it was launching a "special audit" of the budget carrier's operations.
Boeing Co. said on Wednesday it had issued a safety bulletin reminding pilots how to handle erroneous data from a key sensor in the wake of last week's crash in Indonesia.
Analysts say finding the cockpit voice recorder is imperative if investigators are to determine whether the crash has implications for other airlines collectively operating thousands of Boeing 737 flights around the world each day.
"We are formulating, with NTSB and Boeing, detailed inspections regarding the airspeed indicator", he said, according to Reuters. The 2-month-old plane went into a sudden dive minutes after takeoff, which the pilots were able to recover from.
In a statement, the FAA said it plans to mandate the use of Boeing's instructions about sensors.
But he stood and bowed his head after angry and distraught family members demanded that Mr. Kirana, who with his brother Kusnan Kirana founded Lion Air in 1999, identify himself. Lion Air said at its website on Tuesday that the remains of 27 of the 189 missing have been positively identified.
The FAA, which regulates the USA aviation industry, has not received any reports of airspeed issues with the model in the United States, said a person familiar with its reviews, who asked not to be named as he was not authorised to speak. "Is this fatal? NTSC wants to explore this", he said.
The warning comes as Indonesia's transport ministry has scheduled a briefing to share the latest information on the Lion Air tragedy.
The glitch had been repeatedly serviced and Lion Air's technical team declared the plane to be airworthy.
The grieving families of the victims of flight JT-610 may have to wait for a long time before they receive confirmation of the identities of their loved ones.
At least 105 body bags containing body parts of the passengers have been handed to the disaster victim identification unit of the national police hospital in Jakarta.
That included three flights that landed safely, as well as the deadly crash on October 29, when flight JT610 crashed minutes after takeoff from Jakarta, Indonesia, with 189 people on board.
As per reports, the pilots had requested to return to Jakarta, before losing contact with the air traffic controller, 13 minutes after it took off at 6.20am and after it had reached an altitude of 5,400 feet. Kirana and brother Kusnan Kirana founded Lion Air in 1999.
Boeing said it is cooperating fully and providing technical assistance as the investigation continues.
