Last month, the Federal Aviation Administration began to ever so slowly ease its strict oversight of Boeing.

Certification of the 777X requires a series of flight tests specific to what’s called Type Inspection Authorization (TIA), issued by the Federal Aviation Administration. Typically, TIA is a one-step authorization. The FAA is granting this in stages, to the frustration of Boeing and CEO Kelly Ortberg.

Certification of the 737 MAX 7 and MAX 10 derivatives was paused during the 21-month grounding of the MAX 8 and MAX 9 following the March 10, 2019, crash of the second MAX 8 within five months. The two accidents killed 346 people; the root cause was traced to a design flaw within software that pushed the nose of the MAX down in the event a potential stall was detected.

During the lengthy investigation of the MAX crashes, further flaws of a less serious nature were identified. The FAA required these to be fixed before the 7s and 10s are certified. This process has not gone smoothly. According to information provided to LNA, the unintended consequences of new legislation adopted by Congress during the MAX investigation appear to be causing repeated delays in certifying the MAX in addition to some nettlesome technical issues.

Additionally, action by the Trump Administration to eliminate jobs across the government, including the FAA, as part of its Department of Government Efficiency (DOGE) killed some jobs tied to aircraft certification.
