Senators Call for 'Detailed' Investigation Into Boeing

Senators are calling for a broader investigation into Boeing’s safety and manufacturing practices after a whistleblower alleged issues with the structural integrity of the 787 Dreamliner and 777. 

“There are mounting serious allegations that Boeing has a broken safety culture and a set of practices that are unacceptable,” said Senator Richard Blumenthal, the chair of the Senate Homeland Security and Governmental Affairs subcommittee on investigations, during a hearing Wednesday on Boeing’s safety culture. 

The hearing featured testimony from Boeing engineer Sam Salehpour, who came out last week with allegations that the 787 and 777 were not assembled to code. 

Salehpour, who has worked at Boeing for more than a decade, claimed the plane maker took shortcuts in manufacturing the 787, saying he saw “people jumping on pieces of the airplane” to close the gaps on the fuselage. Gaps in the fuselage are supposed to be closed through a process known as shimming, where small pieces of material are used to fill in those gaps. 

Salehpour’s testimony came on the heels of an interview with NBC News Tuesday in which  he called for the 787 to be grounded. 

At the Senate hearing, Salehpour doubled down on his claims. 

“I have analyzed Boeing’s own data to conclude that the company is taking manufacturing shortcuts on the 787 program that may significantly reduce the airplane safety and the life cycle,” he said at the hearing. 

Boeing previously halted deliveries of the 787 Dreamliner in 2021 due to issues with the gaps in the fuselage. Salehpour is claiming that these issues still exist. 

“When you are operating at 35,000 feet, details that are the size of a human hair can be a matter of life and death,” Salehpour said. 

Boeing has refuted Salehpour’s claims, saying that it is fully confident in the 787 Dreamliner and 777.

“In 13 years of service, the global 787 fleet has safely transported more than 850 million passengers on more than 4.2 million flights,” Boeing said in a statement. “A 787 can safely operate for at least 30 years before needing expanded airframe maintenance routines. Extensive and rigorous testing of the fuselage and heavy maintenance checks of nearly 700 in-service airplanes to date have found zero evidence of airframe fatigue.”

The U.S. plane maker held a two-hour long press conference earlier this week where it defended the production process of the 787 and 777. Boeing said that it has made changes to the manufacturing process of the 787, but they didn’t affect the durability or structural integrity of the aircraft. 

Salehpour said after raising concerns about the 787 with his manager, he was moved to the 777 program, where he observed that parts were not installed properly. 

Boeing said it has
