Jakarta - A new information revealed the Lion Air Boeing 737 MAX 8 had the same failure the day before the crash and was saved by an off-duty pilot on board who diagnosed the problem.
The off-duty pilot, who was also seated in the cockpit, correctly identified the problem and told the crew to cut the power of the motor trimming the horizontal stabilizer, Bloomberg news agency reports.
The next day, the aircraft crashed into the Java Sea near Jakarta because of erroneous Angle of Attack data under the command of a different crew.
The event was not mentioned in the report of Indonesia’s National Transportation Safety Committee dated November 28.
“All the data and information that we have on the flight and the aircraft have been submitted to the Indonesian NTSC. We can’t provide additional comment at this stage due to the ongoing investigation on the accident,” Lion Air spokesman Danang Prihantoro told Bloomberg.
The report of the Indonesian safety committee also indicated that the Lion Air's Boeing 737 MAX 8 had had the same failure on previous flights and hadn’t been correctly fixed.
