Transportation and Infrastructure Committee Leaders Request OIG Review of FAA's Boeing 787 Oversight

WASHINGTON, D.C. - Chair of the House Committee on Transportation and Infrastructure Peter DeFazio (D-OR), Ranking Member Sam Graves (R-MO), Chair of the Subcommittee on Aviation Rick Larsen (D-WA) and Subcommittee Ranking Member Garret Graves (R-LA) requested the U.S. Department of Transportation's Office of Inspector General (OIG) conduct a review of the FAA's oversight of the manufacture and production of the Boeing 787.

The Members highlighted several concerns in their letter: "In October 2020, Boeing halted delivery of new 787s to customers for multiple months due to production issues. During 2021, Boeing restarted deliveries in March, but Boeing identified additional production issues and halted deliveries in May. Production was again halted in July, and deliveries currently remain paused."

The Members concluded by requesting the OIG evaluate whether the FAA's existing inspection program is sufficient to identify production issues, including whether FAA has enough inspectors, whether FAA performs enough inspections, and whether FAA has appropriate processes in place to identify production issues. They also asked the OIG to review and evaluate the effectiveness of the FAA's actions to resolve 787 production issues.

The full letter text can be found below and here.

Inspector General

Department of Transportation

1200 New Jersey Avenue S.E.

Dear Inspector General Soskin:

Over the past three years, there has been much attention on the design, development, and certification of the Boeing 737 MAX and its return to service following two fatal accidents. We appreciate the work your office has done to date to evaluate the actions of the Federal Aviation Administration (FAA) and Boeing related to the 737 MAX. We are writing to request that the Department of Transportation's Office of Inspector General (OIG) conduct a review of the FAA's oversight of the manufacture and production of the Boeing 787.

In October 2020, Boeing halted delivery of new 787s to customers for multiple months due to production issues.[1] During 2021, Boeing restarted deliveries in March, but Boeing identified additional production issues and halted deliveries in May.[2] Production was again halted in July, and deliveries currently remain paused.[3] Below are some production issues identified in news reports at Boeing's Charleston, South Carolina, 787 plant:

• August 2020: Boeing recommended airlines ground eight recently manufactured 787 aircraft to address a manufacturing flaw in the joining of two carbon fiber composite structures that seal the aircraft's pressurized cabin.[4] Around the same time Boeing also discovered that "shims" used to fill gaps when two fuselage panels are joined together during production assembly were being improperly manufactured.[5]

• September 2020: Boeing disclosed that during the assembly process of the 787 some aircraft had their horizontal stabilizers clamped together with too much force, violating a manufacturing requirement.[6]

• March 2021: Boeing announced it was inspecting flight-deck windows of some 787s for potential manufacturing flaws in a limited number of aircraft.[7]

Additionally, in February 2021, the FAA published an airworthiness directive (AD) requiring visual inspection of the decompression panels in the bilge barriers located in the forward and aft cargo compartments of approximately 222 Boeing 787 Dreamliner aircraft to look for damaged or disengaged decompression panels due to previous incidents with these panels.[8]

While the FAA continues to investigate, we request that your office:

1. Evaluate whether the FAA's existing inspection program is sufficient to identify production issues, including whether FAA has enough inspectors, whether FAA performs enough inspections, and whether FAA has appropriate processes in place to identify production issues; and
2. Review and evaluate the effectiveness of the FAA's actions to resolve 787 production issues.

We look forward to the results of your review into the FAA oversight processes related to the production of the Boeing 787. We appreciate your attention to this matter. If you or your staff have any questions, please contact Majority Aviation Subcommittee staff and Minority Aviation Subcommittee staff.

Sincerely,

PETER DeFAZIO
