The United States Air Force (USAF) Air Combat Command (ACC) grounded the F-35A Lightning II fleet during Martin-Baker Ejection Seat Device (CAD) testing.
On July 29, ACC grounded its F-35 aircraft “out of an abundance of caution,” according to a statement to Janes July 29. ACC began a 90-day inspection period on July 19 and shut down the park to expedite the process.
According to Martin-Baker’s Aug. 1 statement, the CAD problem was discovered during a “routine inspection” at Hill Air Force Base in Utah in April 2022.
