(NewsNation) — Lawmakers on Tuesday will question Boeing CEO David Calhoun about plans to fix manufacturing issues on the heels of a 204-page report laying out new whistleblower allegations.
The Senate investigations subcommittee released the report hours before Calhoun was set to appear. It includes allegations from Sam Mohawk, a quality assurance investigator at a 737 assembly plant near Seattle. According to Mohwak, Boeing has used “nonconforming” parts in its 737 Max Jets build. Mohawk says the company hid evidence of the situation after it learned more than a year ago that the Federal Aviation Administration would inspect the plant, the Associated Press reported.
Tuesday’s hearing will be the first time since January that a high-ranking Boeing official has go before Congress.
The company has encountered a series of safety issues in the past year, starting in January when a door plug flew off an Alaska Airline plane. Later that month, a Boeing 747 was traveling to Luis Muñoz Marin International Airport in Puerto Rico when the crew reported an engine failure.
In April, a whistleblower who said all Boeing 787 Dreamliner jets should be grounded testified that no one listened when he previously brought up safety concerns to the aerospace company.
Calhoun is expected to step down by the end of the year as part of a broader management shakeup, Reuters reported.
