Pilots unable to correct for faulty sensor that sent Indonesian flight plunging into the sea, report says
By Stanley Widianto, Ashley Halsey III and Aaron Gregg November 28 at 6:30 AM
JAKARTA, Indonesia A malfunctioning sensor and an automated response from the aircrafts software stymied pilots efforts to control a doomed Indonesian flight that went careening into the sea, according to a preliminary investigative report released Wednesday.
The report, which stops short of determining the cause of the crash or analyzing findings, chronicles the chaotic moments on the Lion Air flight before it crashed into the waters off the coast of Java last month, killing all 189 passengers and crew on board.
It details how sensors and other equipment were checked and fixed before the aircrafts final flight, but not the angle of attack sensor, which measures where the nose is pointing and was showing erroneous readings throughout the short time the plane was airborne.
With the sensor insisting the nose was too high, an automatic feature kicked in, sending the plane plummeting as the pilots wrestled to regain control. Unable to trust their readings, the pilots resorted to asking air traffic control what their speed and altitude were.

Lion Air crash: Investigators say plane was 'not airworthy'
28 November 2018
Indonesian investigators have said the Lion Air plane that crashed last month killing 189 people was not airworthy and should have been grounded.
The Boeing 737 Max plane crashed into the Java Sea shortly after departing from Jakarta on 29 October.
A preliminary report has found technical problems had been reported on previous flights.
The 737 Max is a new version of Boeing's original 737 and has become its fastest selling plane.
