A former senior manager at Boeing said he repeatedly warned company executives about production issues at the factory where the 737 Max jets were being built, but his recommendations to shut down production were rebuffed.
Edward Pierson, who was a senior manager at Boeing’s Renton, Wash., factory, said a push to increase production of the 737 Max from 47 a month to 52, created a “factory in chaos.”


Employees were working seven days. Overtime had more than doubled and in some cases, Pierson said, employees were doing jobs for which they had no training.
“The factory did not have enough skilled employees, specifically mechanics, electricians and technicians to keep up with the backlog of work,” Pierson said in remarks prepared for a hearing Wednesday before the House Transportation Committee. “I witnessed numerous instances where manufacturing employees failed to communicate effectively between shifts, often leaving crews to wonder what work was properly completed.”
