Boeing executive Ted Colbert is out as head of the troubled firm’s defense sector, effective immediately, the company announced Friday.

Kelly Ortberg, Boeing’s chief executive, said in a memo to employees that Steve Parker will temporarily lead Boeing Defense, Space and Security until a permanent replacement for Colbert is named. Parker is the chief operating officer for Boeing’s $32.7 billion defense sector.

In the memo, Ortberg thanked Colbert for 15 years of service to Boeing. But he also spoke about the need for Boeing — which has had a series of prominent failures over the last year — to do better.

“At this critical juncture, our priority is to restore the trust of our customers and meet the high standards they expect of us to enable their critical missions around the world,” Ortberg said. “Working together we can and will improve our performance and ensure we deliver on our commitments.”

Colbert took over Boeing’s defense sector in March 2022 after running Boeing Global Services. Later that year, he reorganized it amid steep revenue losses and quality concerns.

Colbert also stuck firm to the company’s commitment to no longer agree to fixed-price contracts with the Pentagon. Such contracts have led to billions of dollars in losses for Boeing, leading the company to swear them off, even if it meant passing on some major programs like the Survivable Airborne Operations Center, or SAOC.

At the Farnborough Air Show in England in July, Colbert told reporters that the Air Force’s plan for SAOC would have required Boeing to agree to fixed-price elements and other components it felt were unacceptable. He said if the Air Force were to require fixed-price deals for its new collaborative combat aircraft autonomous drones, Boeing would similarly steer clear of that program.

“If it’s a fixed-price development program that requires a ton of maturity … that is a recipe for failure,” Colbert said.

But losses at Boeing Defense continued during Colbert’s tenure. The sector lost $1.8 billion in 2023 and is down $762 million so far in the first half of 2024.

Colbert’s removal marks Ortberg’s first major management change since taking the reins of Boeing last month.

And it comes nearly two weeks after Boeing’s Starliner space capsule returned to Earth from the International Space Station without its crew amid safety concerns.

During Starliner’s June 5 flight to the space station, engineers observed several helium leaks and problems with its thrusters, according to NASA. NASA and Boeing engineers spent nearly three months testing thrusters and reviewing data to try to figure out how to fix the problems. But on Aug. 24, NASA determined it was too risky to fly the two astronauts home on Starliner and opted to instead bring them home on a planned SpaceX mission next February.

Ortberg is trying to put Boeing back on course after years of quality and safety troubles with aircraft such as the Max airliners, the KC-46 Pegasus refueling tanker and the new Air Force One presidential transport planes, which upended the company’s once-strong reputation as an aerospace giant.

Boeing is also reeling from a massive strike declared Sept. 13 by tens of thousands of its machinists, which is also impacting the firm’s defense programs like the KC-46. Ortberg has been speaking directly with workers to try to find a way to resolve the disagreement over issues such as pay and end the strike, the company said. A lengthy strike would harm its production, deliveries and operations.

In July, Boeing pleaded guilty to conspiracy to defraud the United States over charges stemming from the crashes of two 737 Max aircraft. In January, the door plug of another 737 Max blew out midflight, with videos of the frightening scene aboard going viral. The incidents prompted congressional hearings into Boeing’s safety problems.

NATIONAL HARBOR, Maryland — Air Force Special Operations Command has returned about 60% of its CV-22 Osprey fleet to fully operational flight status and expects to once again deploy the tilt-rotor aircraft to support combatant commands in a matter of weeks.

In a roundtable with reporters at the Air and Space Forces Association’s Air Space Cyber conference, AFSOC commander Lt. Gen. Michael Conley said the command is clearing about three Ospreys for flight operations every 10 days as it gradually lifts the fleet’s grounding.

AFSOC has roughly 50 CV-22s, and expects to have all its Ospreys back to normal flying operations by late 2024 or early 2025. Conley would not say where Ospreys are likely to deploy.

The military in December 2023 grounded all its V-22s, which are flown by AFSOC, the Navy and the Marine Corps, following the fatal crash of an Air Force Osprey off the coast of Japan a week earlier. That crash killed all eight crew members aboard.

An Air Force investigation later found the crash was caused in part by cracks in a crucial gear driving the tilt-rotor aircraft’s proprotors, and also by the pilot’s decision not to land the aircraft after multiple alerts known as “chip burn warnings” sounded in the aircraft. Those alerts let Osprey air crews know when metal flakes are starting to come off of its gears, which can be a sign the aircraft is stressed.

After a three-month grounding, the Pentagon announced it would start to return its Osprey fleet to flight operations, after revising training for troops flying them and changing maintenance procedures. There were no equipment modifications instituted as a prerequisite for returning the aircraft to flight.

AFSOC put new operating guidance in place earlier this year to require Osprey pilots to land sooner when chip burn warnings go off, Conley said. Now, Osprey air crews are instructed to land as soon as practical after the first warning sounds, and after a second, land as soon as possible.

Pilots always have discretion to fly their aircraft the way they think it requires, Conley said, since each flight has its own unique circumstances. But the tighter guidance on landing is meant to “make it less ambiguous to the crews” to decide what they should do in dangerous situations.

AFSOC had to quickly requalify its Osprey instructors and evaluators before it could start retraining air crew members, Conley said.

And Conley said AFSOC has been “very deliberate and slow and methodical” as it goes through its Osprey fleet one by one, and paying particular attention to aircraft parts.

Naval Air Systems Command Boss Vice Adm. Carl Chebi, who oversees the military’s Osprey program, told lawmakers in June that the entire V-22 fleet would likely not be back to normal flight operations until at least mid-2025.
