A report by Indonesian investigators states that Xtra Aerospace had miscalibrated a sensor on Lion Air 737 which gave erroneous readings and led to the activation of an anti-stall system which pushed the plane’s nose downwards and led to the crash of the aircraft.
The U.S. Federal Aviation Administration (FAA) has issued an order which revokes the repair station certificate of Xtra Aerospace LLC.
Xtra Aerospace LLC had repaired a sensor suspected of contributing to the crash of a Lion Air 737 MAX a year ago.
“Xtra failed to comply with requirements to repair only aircraft parts on list of parts acceptable to the FAA that it was capable of repairing,” said the FAA.
The final report into the Lion Air 737 MAX crash by Indonesian investigators had recommended that the FAA improve oversight of maintenance organizations.
The report states, Xtra Aerospace had conducted a repair on a Lion Air sensor that was miscalibrated and gave erroneous readings that led to the activation of an anti-stall system that pushed down the plane’s nose.
