More recently, a third whistleblower made headlines when testifying before a senate committee last year.
Sam Salehpour, a current Boeing employee, told US lawmakers he had come forward because “the safety problems I have observed at Boeing, if not addressed could result in a catastrophic failure of a commercial aeroplane that would lead to the loss of hundreds of lives”.
The quality engineer said that while working on the 787 in late 2020, he had seen the company introduce shortcuts in assembly processes, in order to speed up production and delivery of the aircraft. These, he said, “had allowed potentially defective parts and defective installations in 787 fleets”.
He also noted that on the majority of aircraft he looked at, tiny gaps in the joints between sections of fuselage had not been properly rectified. This, he said, meant those joints would be prone to “premature fatigue failure over time” and created “extremely unsafe conditions for the aircraft” with “potentially catastrophic” consequences.
He suggested that more than 1,000 aircraft – the bulk of the 787 fleet – could be affected.
Boeing insists that “claims about the structural integrity of the 787 are inaccurate”. It says: “The issues raised have been subject to rigorous examination under US Federal Aviation Administration oversight. This analysis has validated that the aircraft will maintain its durability and service life over several decades, and these issues do not present any safety concerns.”
