A former Boeing quality control engineer has claimed that passengers on its 787 Dreamliner could be left without oxygen if the cabin were suffered a sudden decompression.
Mr Barnett, a former quality control engineer, worked for Boeing for 32 years, until his retirement on health grounds in March 2017 and he made an interview with BBC claiming that quarter of the oxygen systems could be faulty and might not work when needed.
Boeing is under increasing pressure after two catastrophic crashes in Lion Air and Ethiopian Airlines of Boeing 737 Max and they came under scrutiny after improper work has been done with MCAS system.
However, now new doubts have been raised for their other popular model – 787 Dreamliner. Mr Barnett also claims that faulty parts were deliberately fitted to planes on the production line at one Boeing factory to speed up the process of production in order to gain more profit thus compromising safety.
Boeing denies his accusations and says all its aircraft are built to the highest levels of safety and quality.
