FAA investigat­ing new claims of design flaws in Boeing aircraft

Engineer says company has fuselage concerns with its 787 Dreamliner.

WASHINGTON — The Federal Aviation Administra­tion is investigat­ing claims made by a Boeing engineer who says that sections of the fuselage of the 787 Dreamliner are improperly fastened together and could break apart mid-flight after thousands of trips.

The engineer, Sam Salehpour, who worked on the plane, detailed his allegation­s in interviews with The New York Times and in documents sent to the FAA. A spokespers­on for the agency confirmed that it was investigat­ing the allegation­s but declined to comment on them.

Salehpour, who has worked at Boeing for more than a decade, said the problems stemmed from changes in how the enormous sections were fitted and fastened together in the assembly line. The plane’s fuselage comes in several pieces, all from different manufactur­ers, and they are not exactly the same shape where they fit together, he said.

Boeing conceded those manufactur­ing changes were made, but a spokespers­on for the company, Paul Lewis, said there was “no impact on durability or safe longevity of the airframe.”

Lewis said Boeing had done extensive testing on the Dreamliner and “determined that this is not an immediate safety of flight issue.”

“Our engineers are completing complex analysis to determine if there may be a long-term fatigue concern for the fleet in any area of the airplane,” Lewis said. “This would not become an issue for the in-service fleet for many years to come, if ever, and we are not rushing the team so that we can ensure that analysis is comprehens­ive.”

In a subsequent statement, Boeing said it was “fully confident in the 787 Dreamliner,” adding that “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.”

Salehpour’s allegation­s add another element to the intense scrutiny that Boeing has been facing since a door panel blew off a 737 Max jet during an Alaska Airlines flight in early January, raising questions about the company’s manufactur­ing practices. Since then, the plane-maker has announced a leadership overhaul, and the Justice Department has begun a criminal investigat­ion.

Salehpour’s concerns are set to receive an airing on Capitol Hill. Sen. Richard Blumenthal, D-Conn., the chair of the Senate Homeland Security and Government­al Affairs Committee’s investigat­ions subcommitt­ee, is planning to hold a hearing with Salehpour on April 17. Blumenthal said he wanted the public to hear from the engineer firsthand.

“Repeated, shocking allegation­s about Boeing’s manufactur­ing failings point to an appalling absence of safety culture and practices — where profit is prioritize­d over everything else,” Blumenthal said in a statement.

Dreamliner issues

The Dreamliner is a wide-body jet that is more fuel-efficient than many other aircraft used for long trips, in part because of its lightweigh­t composite constructi­on. First delivered in 2011, the twinaisle plane has racked up orders for Boeing but also has created headaches for the company.

For years, the plane-maker has dealt with a succession of issues involving the jet, including battery problems that led to the temporary grounding of 787s around the world and quality concerns that more recently caused an extended halt in deliveries.

Boeing also has confronted a slew of problems at its plant in South Carolina where the Dreamliner is built. A prominent Boeing whistleblo­wer who raised concerns about manufactur­ing practices at the plant, John Barnett, was found dead last month with what appeared to be a selfinflic­ted gunshot wound.

The Dreamliner was a pioneer in using large amounts of so-called composite materials rather than traditiona­l metal to build the plane, including major sections such as the fuselage, as the aircraft’s body is known. Often made by combining materials such as carbon and glass fibers, composites are lighter than metals, but, as comparativ­ely newer materials, less is known about how they hold up to the long-term stresses of flight. Those stresses create what engineers call fatigue, which can compromise safety if it causes the material to fail.

Shortcuts alleged

Salehpour said he was repeatedly retaliated against for raising concerns about shortcuts he believed that Boeing was taking in joining together the pieces of the Dreamliner’s fuselage.

Debra S. Katz, a lawyer for Salehpour, said her client raised his concerns with supervisor­s and tried to discuss them in safety meetings — but, she said, company officials did not listen.

Instead, she said, Salehpour was silenced and transferre­d to work on another wide-body aircraft, the 777.

Salehpour said that after his transfer, he found additional problems with how Boeing was assembling the fuselage of the 777.

“This is the culture that Boeing has allowed to exist,” Katz said. “This is a culture that prioritize­s production of planes and pushes them off the line even when there are serious concerns about the structural integrity of those planes and their production process.”

In its statement, Boeing said it has encouraged its workers “to speak up when issues arise” and that retaliatio­n was “strictly prohibited.”

The FAA interviewe­d Salehpour last week, Katz said. In response to questions about the Dreamliner, Mike Whitaker, the agency’s administra­tor, reiterated that the regulator was taking a hard line against Boeing after the Alaska Airlines episode.

“This won’t be back to business as usual for Boeing,” Whitaker said in a statement. “They must commit to real and profound improvemen­ts. Making foundation­al change will require a sustained effort from Boeing’s leadership, and we are going to hold them accountabl­e every step of the way.”

John Cox, a former airline pilot who runs a safety consulting firm, said that while composites are more tolerant of excess force than metals, it is harder to see that composites have been stressed to the point that they would fail. “They just snap,” he said. “The catastroph­ic in-flight breakup, yes, that’s a theoretica­l possibilit­y,” Cox said. “That’s why you’d want to have the testing done to preclude that.”

Boeing’s tests are an appropriat­e step, Cox said, because “if the degradatio­n goes far enough, that could potentiall­y lead to a catastroph­ic failure.”
