Boeing mounted a vociferous protection of its 777 and 787 Dreamliner wide-body applications Monday, days after a whistleblower alleged that the plane-maker had taken manufacturing shortcuts that launched potential structural flaws to each plane varieties.
On Monday, Boeing held an uncommon media briefing from its Dreamliner meeting plant in North Charleston, South Carolina, the place it detailed the specifics of the way it assembles the 787 from a number of elements which can be constructed and delivered disassembled, such because the fuselage, wings and tail part, and the structural testing every element undergoes.
In refuting the allegations and characterizations introduced by the whistleblower, Boeing provided a pointy distinction from the conciliatory and concessional tone it is introduced this 12 months by the continuing 737 MAX disaster, which in the end led to the ousting of the corporate’s CEO.

The whistleblower, a Boeing engineer named Sam Salehpour, alleged final week that a whole bunch of 787 and 777 jets had been liable to structural failure from injury attributable to fatigue. The allegations had been detailed in The Seattle Times.
He additionally mentioned that he was harassed by Boeing in consequence.
Salehpour’s 787 allegations surrounded tiny gaps between fuselage sections that stay after Boeing joined them collectively.
The areas had been first found in 2020, which led Boeing to halt deliveries of the long-haul jet for almost two years. The Federal Aviation Administration investigated Boeing’s manufacturing program and authorised a repair, and at present inspects every particular person 787 earlier than approving it for supply to an airline buyer.
Salehpour alleged, nonetheless, that the issue was not truly mounted, and that Boeing used extreme pressure to push the items collectively, making it seem as if the gaps had been gone, relatively than utilizing small items of filler materials to fill them — a observe referred to as “shimming.”

Shimming is used to fill gaps bigger than five-thousandths of an inch, which prevents items from shifting round throughout flight and bearing extra stress.
On the 777, Salehpour alleged that fuselage panels had been delivered from a vendor that didn’t match correctly, and mentioned that manufacturing unit employees jumped on items of the fuselage to jam them into place, doubtlessly deforming them. He claimed that he was moved to the 777 program as retaliation after elevating considerations concerning the 787.
Boeing final week was fast to refute Salehpour’s claims by arguing that every one of its 787s meet specs required for certification.
“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,” Boeing mentioned in a press release final week offered to TPG. “The issues raised have been subject to rigorous engineering examination under FAA oversight. This analysis has validated that these issues do not present any safety concerns and the aircraft will maintain its service life over several decades.”
On Monday, Boeing engineers outlined the manufacturing course of in specifics, together with the stress testing that it says proves every little thing on the 787 is inside its specified parameters.
“Extensive design analysis and testing that validates all of the decisions we’ve made,” mentioned Steve Chisholm, a vice chairman and useful chief engineer of mechanical and structural engineering at Boeing.
Chisholm additionally mentioned that Boeing encourages staff to talk up about issues or considerations they observe, and mentioned that such reporting is essential to the corporate’s security processes.
“Having the voices of our employees heard is of utmost importance,” he mentioned. “We do believe this makes us stronger. And it’s something we’ve really been leveraging and emphasizing.”
In addition to an ethics hotline, Boeing staff can use a system known as “Speak Up” to report points anonymously, Lisa Fahl, a Boeing vice chairman of airplane applications engineering, mentioned Monday.
“You have full visibility to the FAA, and that’s a system where we go through and we do an investigation and an evaluation must be performed and documented to support anything that’s brought forward,” she mentioned.
The FAA is investigating Salehpour’s claims, in keeping with The New York Times.
In response to questions from TPG, an FAA spokesperson mentioned that the company continued to implement its prescribed fixes for the shimming concern, which incorporates issuing ongoing Airworthiness Directives (ADs) concerning inspection and repairs, together with inspecting all newly constructed plane earlier than they’re delivered.
“Every aircraft flying is in compliance with the ADs. Boeing has either completed or is working on long-term corrective actions. The FAA continues to issue Airworthiness Certificates for every Boeing 787 before they enter service.”
An FAA spokesperson additionally famous that Boeing investigates all whistleblower experiences.
“Voluntary reporting without fear of reprisal is a critical component in aviation safety,” the spokesperson mentioned. “We strongly encourage everyone in the aviation industry to share information.”
The background: What to know concerning the Boeing 737 MAX 9 and the MAX collection
The report comes amid a mounting disaster surrounding Boeing’s high quality management on its narrow-body 737 program, stemming from a Jan. 5 incident through which a physique panel go off an Alaska Airlines 737 MAX 9 throughout a flight a couple of minutes after it departed from Portland International Airport (PDX) in Oregon.
Boeing CEO Dave Calhoun mentioned he would step down by the top of the 12 months, whereas business airplane chief Stan Deal resigned final month.
