Boeing 737 Max jets involved in several mid-air emergencies
Boeing 737 Max planes had at least six mid-air emergencies since the aircraft was cleared to fly again.
There were also pre-flight issues which led to groundings in the past year, according to US air safety data.
It included engine shutdowns and in an incident in December 2021, a United pilot declared a mayday when the altitude system of the plane started malfunctioning.
The US plans to conduct a new audit assessing Boeing’s production oversight of the planes.
It follows an investigation by ABC.
“The DOT Inspector-General’s office confirmed … that Congress requested an audit of Boeing’s production oversight and that the review of the production of the 737 MAX will be a part of this audit,” an NTSB email said.
Data showed the plane’s flight control system failed on 22 separate flights.
There were more than 40 occasions when flights were grounded due to initial equipment failure.
One Alaska Airlines Max had to be grounded seven times in five months due to recurring problems with its navigation equipment.
