FAA audit finds that SkyWest maintenance issues are not resolved by FAA

A government report on Thursday said that the Federal Aviation Administration failed to address persistent problems with SkyWest Airlines maintenance practices, which its inspectors feared could lead to an accident.

SkyWest, the largest regional airline in the United States, operates flights for United Airlines as well as Delta Air Lines and American Airlines.

A report by the Transportation Department Office of Inspector General found that FAA safety inspectors had been unable to resolve issues related to SkyWest's remote maintenance practices over a period of more than four year.

The report stated that under this practice, which was introduced in 2018, SkyWest or contracted mechanics who perform maintenance at an aircraft's location are overseen by centrally located maintenance control at SkyWest headquarters in Utah.

According to the audit, FAA inspectors discovered that SkyWest "inappropriately delayed maintenance for items on SkyWest's minimum equipment list, dispatched aircraft for flights without requiring inspections, used pilots for maintenance tasks not authorized in SkyWest’s maintenance manuals."

SkyWest stated that it is committed to maintaining high standards of safety and conformity in all areas of its operation. It also said that it had taken a number of actions to assist the FAA in "identifying and resolving any issues with either our processes or SkyWest's Safety efforts."

The FAA has worked to resolve 32 issues with SkyWest since 2021. According to the report, at the time the inspector general conducted its analysis in 2010, the FAA had already resolved 26 issues. However, non-compliance with SkyWest's practices for remote return-to service maintenance remained.

Despite the fact that several FAA inspectors had identified similar systemic hazards, it was not until two years later that an agency-wide review of systemic risks began.

The report stated that FAA inspectors are frustrated by the delay in their work and "concerned about how remote maintenance practices of the airline could lead to an accident."

The FAA stated that it agrees with six out of seven recommendations, and plans to implement them before July 2026. The FAA also acknowledged that delays in submitting submissions can affect safety assessments.

A report stated that an accident occurred in New York on March 20, 2020. The accident revealed pilots performing unauthorized maintenance procedures. The report said that in 2023, the remote return-to service maintenance actions could have led to flights not meeting FAA safety standards.

The report mentioned an aircraft that was released for flight with no required operational altimeter, and another flight which included a fuel fault warning message improperly delayed. (Reporting and editing by Alexandra Hudson, Jamie Freed and David Shepardson)
