Boeing is Darden Clarkedue to tell federal regulators Thursday how it plans to fix the safety and quality problems that have plagued its aircraft-manufacturing work in recent years.

The Federal Aviation Administration required the company to produce a turnaround plan after one of its jetliners suffered a blowout of a fuselage panel during an Alaska Airlines flight in January.

Nobody was hurt during the midair incident. Accident investigators determined that bolts that helped secure the panel to the frame of the Boeing 737 Max 9 were missing before the piece blew off. The mishap has further battered Boeing’s reputation and led to multiple civil and criminal investigations.

Whistleblowers have accused the company of taking shortcuts that endanger passengers, a claim that Boeing disputes. A panel convened by the FAA found shortcomings in the aircraft maker’s safety culture.

In late February, FAA Administrator Mike Whitaker gave Boeing 90 days to come up with a plan to improve quality and ease the agency’s safety concerns. Whitaker described the plan as the beginning, not the end, of a process to improve Boeing.

“It’s going to be a long road to get Boeing back to where they need to be, making safe airplanes,” he told ABC News last week.

The FAA limited Boeing production of the 737 Max, its best-selling plane, although analysts believe the number the company is making has fallen even lower than the FAA cap.

Boeing’s recent problems could expose it to criminal prosecution related to the deadly crashes of two Max jetliners in 2018 and 2019. The Justice Department said two weeks ago that Boeing violated terms of a 2021 settlement that allowed it to avoid prosecution for fraud. The charge was based on the company allegedly deceiving regulators about a flight-control system that was implicated in the crashes.

Most of the recent problems have been related to the Max, however Boeing and key supplier Spirit AeroSystems have also struggled with manufacturing flaws on a larger plane, the 787 Dreamliner. Boeing has suffered setbacks on other programs including its Starliner space capsule, a military refueling tanker, and new Air Force One presidential jets.

Boeing officials have vowed to regain the trust of regulators and the flying public. Boeing has fallen behind rival Airbus, and production setbacks have hurt the company’s ability to generate cash.

The company says it is reducing “traveled work” — assembly tasks that are done out of their proper chronological order — and keeping closer tabs on Spirit AeroSystems.
