A MECHANIC who worked on Boeing’s 787 Dreamliner alleged he was retaliated against after raising concerns about a subcontractor’s work, according to a statement from attorneys representing him as a whistleblower.
Mechanic Richard Cuevas claimed he observed “substandard manufacturing and maintenance practices” on the 787’s forward pressure bulkhead – a dome shaped piece located in the jet’s nose that’s critical to maintaining cabin pressure, according to a statement by attorneys Debra Katz and Lisa Banks.
In 2023, Cuevas was contracted by an aviation staffing company to do repair work for Spirit AeroSystems Holdings at a Boeing hangar in Everett, Washington, and later at a Spirit supplier. He alleged that he witnessed holes being improperly drilled on the 787 bulkhead in a way that deviated from Boeing’s manufacturing specifications. The changes were made without Boeing’s permission, according to the statement.
The “unauthorised change” caused fasteners to not fit properly into those holes, “seriously undermining the integrity of the aircraft”, his attorneys said in a whistleblower complaint filed with the US Occupational Safety and Health Administration that was made public on Wednesday (Jun 26). His allegations were also laid out in a separate complaint filed with the Federal Aviation Administration (FAA).
Cuevas claimed Spirit fired him in March 2024 after he reported the issues internally, first with Spirit and then with Boeing.
Boeing said that the claims were reported previously and thoroughly investigated. Analysis showed the issues raised posed no safety concerns and were addressed, the company said, adding that it isn’t involved in the personnel decisions of subcontractors.

“Our leadership is aware of the allegations and looking into the matter,” Spirit spokesperson Joe Buccino said. “We encourage all Spirit employees with concerns to come forward, safe in knowing they will be protected.”
Cuevas estimated the alleged problems he observed may impact as many as a dozen planes, according to his attorneys’ statement.
The claims are the latest in a series of allegations flagging concerns about the manufacturing practices of Boeing or its suppliers. Earlier this month, a Boeing quality inspector alleged the company mishandled and lost hundreds of faulty 737 Max parts.
The FAA has received more than 11 times as many Boeing whistleblower reports in the first five months of this year compared to all of 2023. The increase came after a fuselage panel blew off a Boeing jet mid-flight in January.
Boeing has also encouraged employees to submit safety concerns to an internal programme called “Speak Up”. BLOOMBERG
