(NEW YORK) — The Senate Permanent Subcommittee on Investigations published a memo Wednesday including new details about Boeing safety failings relating to the Alaska Airlines door plug incident in January.

The memo — released ahead of Federal Aviation Administration Administrator Michael Whitaker’s planned testimony before the subcommittee on Wednesday — suggested Boeing had failed to ensure adequate standards in multiple areas.

Boeing personnel, the memo said, “continue to feel pressure to prioritize speed of production over quality.”

The Jan. 5 Alaska Airlines incident saw a door plug on flight 1282 blow out minutes after takeoff from Portland, Oregon, leaving a large hole in the side of the Boeing 737 Max 9 plane. The plane safely made an emergency landing and no one was seriously injured.

The memo noted the results of a May 2024 employee survey that found only 47% of workers answered favorably to the statement, “Schedule pressures do not cause my team to lower our standards.”

Training also remains a problem, the memo said. 

“Boeing is failing to ensure many of their employees have the appropriate education, training, skills or experience to effectively perform their assigned tasks,” it read.

The subcommittee said Boeing failed to ensure that nonconforming parts are appropriately documented, stored and dispositioned so that they are not installed on aircraft.

Quality inspection procedures — and FAA review of those procedures — also raised questions as to the qualifications and independence of inspectors, the memo said.

“Boeing personnel are allowed to inspect the quality of their own work,” it read.

“These troubling and recurring safety deficiencies raise questions about the FAA’s ability to oversee the quality and safety of Boeing aircraft through effective and lasting enforcement,” the memo said.

Wednesday’s memo and Whitaker’s testimony are part of a wider inquiry that began on March 19, investigating Boeing’s safety and culture practices following whistleblower allegations.
