Data from the black box which was found on 1 November belonging to last month's ill-fated Lion Air plane crash revealed that its pilots had struggled to control the aircraft
An investigative preliminary report released today, 28 November, revealed that the ill-fated Lion Air plane's pilots had fought to maintain the aircraft from the moment it took off from the airport, reported AP News.
The struggle was apparently due to the Boeing 737's nose being repeatedly forced down because of a malfunctioning sensor. Bloomberg reported that the sensor had not been repaired despite it failing on the plane's previous flight.
The computerised system was installed to prevent the plane's nose from rising too high and causing a stall, but had instead forced the nose down due to the automatic system receiving incorrect sensor readings.
The plane's nose was reportedly forced downward 26 times during the 11-minute flight
The pilots were said to have managed to pull the plane back up multiple times before losing control of it, sending the Lion Air Flight 610 plummeting into the ocean with 189 people on board.
Following the report, Indonesia's transport safety committee (KNKT) explained that it is still "too early" to determine if the anti-stall system was a contributing factor to the crash.
Previous reports revealed that the pilots had not been trained to face such a situation
According to Reuters, Indonesian investigators said that the aircraft's manual had not covered how to handle a situation like the one that led to the crash.
However, the pilots did have access to a checklist which outlined how to turn off errant systems when the plane started nosing downwards at the wrong time, said Indonesian Lion Air instructor Soejono.
According to Quartz, a spokesman said that the pilots had requested to turn back about 19km out from take-off, but had not signalled that there was an emergency.
On 29 October, the Indonesian JT610 flight carrying 189 passengers and crew members crashed near Jakarta
