DOT IG Again Auditing FAA B737 Max
Oversight
The
Department of Transportation Inspector General (IG) office has launched
another audit of the FAA’s certification process of the Boeing 737 Max. This
latest investigation will examine the agency's oversight of the aircraft's
maneuvering characteristics augmentation system (MCAS) and the angle-of-attack
disagree indicator. This is the fourth investigation since 2019 into the FAA's
initial certification of the aircraft in 2017.
MCAS was
cited by safety investigators as a contributing factor in two fatal Boeing 737
Max crashes in 2018 and 2019. In addition, in August 2017 Boeing conceded
that not all 737 Max aircraft were equipped with an AOA disagree alert despite intending
for it to be standard for the fleet. The FAA recertified the Boeing 737 Max 8
in late 2020 after the aircraft was grounded for nearly two years.
"During
the original certification process from 2012 to 2017, Boeing included limited
information on MCAS in its initial briefings to the FAA and presented it as a
modification to the existing speed trim system that would only activate under
certain limited conditions,” the IG said. "Our objectives will be to
evaluate FAA’s compliance with applicable statutes, regulations, and policies
in overseeing Boeing actions for (1) the inoperability of the AOA disagree
alert on the majority of the Max fleet in 2019 and (2) the inclusion of MCAS as
part of the speed trim in the 737 Max design."
