Boeing is in the spotlight as Congress subpoenas a whistleblower to testify about flaws in the planes

Boeing will be in the spotlight during back-to-back hearings on Wednesday, as Congress weighs allegations Major security failures At the besieged aircraft manufacturer.

The first session will include members of an expert panel that found serious flaws in Boeing's safety culture.

The main event will be a second hearing Boeing engineer Who claims that parts of the skin on the 787 Dreamliner planes were not installed properly and could eventually break. The whistleblower's lawyer says Boeing ignored the engineer's concerns and prevented him from speaking to experts about fixing the defects.

The whistleblower, Sam Salehpour, sent documents to the Federal Aviation Administration, which is investigating the quality and safety of Boeing's manufacturing.

Salehpour is scheduled to testify on Wednesday before the Senate Investigations Subcommittee. There is also another Boeing whistleblower — Ed Pearson, the former director of the Boeing 737 program — and two other aviation technical experts on the witness list.

The Democrat who chairs the committee and senior Republicans have asked Boeing to do so Collections of documents Go back six years.

Lawmakers are seeking all records related to the manufacturing of Boeing's 787 and 777 planes, including any safety concerns or complaints raised by Boeing employees, contractors or airlines. Some of the questions seek information about Salehpour's allegations of poor fitment of the carbon composite panels on the Dreamliner.

A Boeing spokesman said the company was cooperating with lawmakers' investigation and offered to provide documents and briefings.

The company says claims about the structural integrity of the 787 are untrue. Two Boeing engineering executives said this week that it's in both Design testing and inspection Of the planes – some of which were 12 years old – no signs of fatigue or cracking were found in the composite panels. They suggested that the material, composed of carbon fiber and resin, is almost resistant to fatigue, which is a constant concern with traditional aluminum airframes.

Boeing officials also denied another claim by Salihpour: that he saw factory workers jumping on parts of the fuselage of 777 planes to get them upright.

Salehpour is the latest whistleblower to emerge with allegations about manufacturing problems at Boeing. The company has been in crisis mode since a door connection panel on a 737 MAX exploded during an Alaska Airlines flight in January. Investigators are focusing on Four screws Which were removed and apparently not replaced during the repair job at the Boeing factory.

The company faces a criminal investigation by the Department of Justice and separate investigations by the Federal Aviation Administration (FAA) and the National Transportation Safety Board.

CEO David Calhoun, who will get down At the end of the year, I stated several times that Boeing was taking steps to improve its manufacturing quality and safety culture. He described the Alaska plane explosion as a “defining moment” from which Boeing would emerge better.

There is a lot of skepticism about such comments.

“We need to look at what Boeing does, not just what it says it does,” said Senator Tammy Duckworth, a member of the Senate Commerce Committee, which will hold its first hearings on Wednesday.

The FAA is also likely to take some hits. Until recently, the agency “passed over a lot of Boeing's repeated bad behavior,” especially when it certified the 737 MAX nearly a decade ago, Duckworth said. Two Max planes crashed in 2018 and 2019, killing 346 people, after faulty activation of a flight control system that the FAA did not fully understand.

As requested by leaders of the Senate Investigations Subcommittee FAA documents Regarding its supervision of Boeing.

The subcommittee hearing on Wednesday will be followed by a Senate Commerce Committee hearing, which is scheduled to hear from members of the expert panel that examined safety at Boeing. The group said that despite the improvements made after the two MAX crashes, Boeing Safety culture remains flawed Employees who raise concerns may face pressure and retaliation.

One witness, MIT aviation lecturer Javier de Luis, lost his sister in the Max II crash.
