The U.S Federal Aviation Administration (FAA) has shut down Xtra Aerospace, the company that supplied a faulty Boeing 737MAX Angle of Attack sensor to Lion Air that triggered the deadly 2018 crash.
The Federal Aviation Administration (FAA) issued an order on 25 Oct, revoking the repair station certificate of Xtra Aerospace, LLC, of Miramar, Fla.
Xtra Aerospace repaired and certified a secondhand angle of attack sensor that was installed on the Lion Air jet to replace a faulty one. According to the final KNKT investigation report, the replacement sensor was mis-calibrated so that the angle it registered was 21 degrees too high, and triggered the uncontrollability of the Aircraft.
According to the order, Xtra failed to comply with requirements to repair only aircraft parts on its list of parts acceptable to the FAA that it was capable of repairing. The company also failed to comply with procedures in its repair station manual for implementing a capability list in accordance with the Federal Aviation Regulations.
Xtra is a repair station certificated under part 145 of the Federal Aviation Regulations.
The FAA began its investigation in November 2018. Investigators looked specifically at the company’s compliance with regulatory requirements that apply to its capability list, and records and work orders for aircraft parts it approved for return to service.
The investigation determined that from November 2009 until May 2019, Xtra failed to complete and retain records in accordance with procedures in its repair station manual to support parts on its capability list.
The company also did not substantiate that it had adequate facilities, tools, test equipment, technical publications, and trained and qualified employees to repair parts on its capability list.
The agency issued the order as part of a settlement agreement with the company. Under the agreement, Xtra waives its right to appeal the revocation to the National Transportation Safety Board or any court.
