A whistleblower claims that Boeing’s 787 Dreamliner is flawed. The FAA is investigating

(CNN) — Federal authorities say they’re investigating after a whistleblower repeatedly raised concerns with two models of Boeing widebody jets, and claimed the company retaliated against him.

Whistleblower Sam Salehpour, a Boeing engineer, alleges that Boeing took shortcuts when manufacturing its 777 and 787 Dreamliner jets, and that the risks could become catastrophic as the airplanes age.

His formal complaint to the Federal Aviation Administration, filed in January and made public on Tuesday, is not specific to the newer 737 Max jet that has been grounded twice by the Federal Aviation Administration.

In response to the complaint, the FAA said it investigates all whistleblower complaints.

“Voluntary reporting without fear of reprisal is a critical component in aviation safety,” the FAA said.  “We strongly encourage everyone in the aviation industry to share information.”

Boeing did not immediately comment on the claims about the 777, but disputed Salehpour’s concerns about the 787.

“These claims about the structural integrity of the 787 are inaccurate and do not represent the comprehensive work Boeing has done to ensure the quality and long-term safety of the aircraft,” the company said in a statement.
