Boeing factory workers say they were pressured to work too fast and asked to perform jobs that they weren't qualified for, including opening and closing the door plug that later blew off an Alaska Airlines jet.
Those accounts from inside the company were disclosed Tuesday, as federal investigators opened a two-day hearing into the blowout, which further tarnished Boeing's safety reputation and left it facing new legal jeopardy.
A Boeing door installer said he was never told to take any shortcuts but everyone faced pressure to keep the assembly line moving.
''That's how mistakes are made. People try to work too fast,'' he told investigators for the National Transportation Safety Board. The installer, along with other workers, was not named in probe documents.
The panel that blew off the Boeing 737 Max in January was made and installed by a supplier, Spirit AeroSystems. It was removed at a Boeing factory so that workers could repair damaged rivets, but bolts that help secure the door plug weren't replaced. It's not clear who removed the panel.
Another member of the Boeing door crew said workers got no special training for door plugs and should not have been asked to open or close the panels.
Boeing workers at the factory in Renton, Washington, have ''been put in uncharted waters to do everybody's dirty work because no one wants to touch it,'' the second worker told investigators. He said Boeing's safety culture is ''garbage. Nobody's accountable.''
The workers' accounts were among more than 3,000 pages of documents released by the NTSB as it began a two-day hearing into the Jan. 5 accident, which left a gaping hole in the plane and created decompression so violent that it blew open the cockpit door and tore off the co-pilot's headset.
