Broken AOA sensor in Lion Air 737 MAX 8 crash linked to a Florida-based aerospace company

Jakarta - A faulty AOA (Angle of attack) sensor that caused a Lion Air Boeing 737 MAX 8 to crash in Jakarta last year was linked to a Florida-based aerospace company in the investigation report.

Indonesian investigators and Boeing have been researching for a while if the repair work implemented to the faulty AOA sensor had a role in the accident.

According to the reports presented to the Indonesian parliament, a Florida-based aerospace company performed the repair of the faulty AOA sensor.

On Oct. 29, false AOA data transmitted from one of the two sensors triggered the anti-stall system of a Lion Air Boeing 737 MAX 8 known as MCAS (Maneuvering Characteristics Augmentation System) and pushed the nose of the aircraft down until it crashed.

Five months later, another Boeing 737 MAX 8 jet from Ethiopian airline plunged to the ground during takeoff as it was the case in the Lion Air crash as well.

Investigators have focused on the role of these sensors in both disasters.

Documents obtained by Bloomberg revealed a Miramar, Florida-based aerospace company, XTRA Aerospace Inc., had repaired the faulty sensor before Flight 610 crashed in Jakarta on Oct. 29.

The sensor was installed on the Lion Air 737 MAX 8 on Oct. 28 in Bali, the report says.
