A whistleblower has raised concerns about potential safety issues with Boeing's 787 Dreamliner planes, alleging that parts were built in an unsafe manner. Richard Cuevas, a mechanic at Strom, a contractor for Boeing's manufacturing partner Spirit Aerosystems, witnessed improperly drilled holes in the forward pressure bulkheads of the planes. Despite Cuevas filing a complaint in October 2023 and subsequently being fired, Boeing claims they investigated and found no safety concerns. However, Cuevas believed the holes could compromise the planes' structure and air pressure, posing risks to passengers. This adds to a growing list of problems for Boeing, including previous whistleblower reports and recent safety failures. The FAA and US Department of Justice are investigating these claims, while Boeing's CEO has apologized for the company's shortcomings. The situation underscores challenges in Boeing's production practices and safety culture, raising doubts about regaining public trust.
