Reported issues with Boeing ' 787 Dreamliner assembly line have been said to stem from the company ’s manufacturing process which allows workers to sign - off on their own work , according to Boeing workers . Gonzalez-Beltran, who has worked as an executive for Toyota and Ford Motor Co., had no experience in the aviation-manufacturing industry before arriving at Boeing and has expanded the self-inspect program, according to The Post and Courier. The errors were said to include debris in engines and planes , loose cabin seats , cut wires , untested gears and faulty hydraulics systems . Workers said that 90 % of the manufacturing process was self - checked to speed production , and that most of the issues were discovered by other workers prior to delivery to customers .
