USAF grounds B-1B fleet again

Fri Mar 29, 2019 2:56 am

The new issue appears to be related to the drogue chute system associated with the ejection seats.

According to a release from Global Strike Command, an inspection crew found a potential problem with the drogue chute system, which corrects the seat’s angle to allow an airman to safely depart the bomber.

“During a routine inspection of the B-1B drogue chute system, potentially fleet-wide issues were identified with the rigging of the drogue chute,” the Air Force said.

“It appears to be a procedural issue and is unrelated to the previous problem with egress system components. As a precautionary measure, the commander directed a holistic inspection of the entire egress system," the release said.

It's unclear how long the bombers will be grounded.

B-1Bs are back in the air again.

First B-1Bs resume flying after nearly month-long grounding

The first B-1B Lancer bombers are back in the air after concerns over its ejection seats grounded the entire fleet nearly a month ago, Air Force Global Strike Command said Tuesday.

The B-1B fleet was grounded by Gen. Timothy Ray, commander of Global Strike Command, March 28 over concerns with the drogue chute system, which corrects the seat’s angle to allow an airman to safely eject from the bomber. It was the second time in a year the Air Force grounded the Lancer over an ejection seat issue.

B-1Bs will be returned to flight status individually, as inspections and maintenance are finished on them, the command said in Tuesday’s news release.

Maintenance personnel and aircrew flight equipment technicians inspected the entire ejection system during the stand-down, before clearing each aircraft to fly again.

“We are proud of the tremendous efforts of our maintainers and aircrew flight equipment technicians in identifying, inspecting and remediating any potential issues with the B-1B egress system,” Maj. Gen. James Dawkins Jr., commander of the 8th Air Force, said in the release. “The aircraft are still safe to fly and we are confident that this stand-down has resulted in increased safety within the B-1B fleet.”

The B-1 hasn't had a great year, looks like the fleet is struggling through some big inspections. Given the extended duration the fleet had been deployed over the last 18 years it is no surprise that they are now struggling to keep a majority of the fleet available.

Only a Handful of the Air Force's B-1 Bombers Are Ready to Deploy

Despite high demand, there are only a handful of B-1B Lancer bombers available to take off at a moment's notice.

The head of U.S. Strategic Command (STRATCOM), Air Force Gen. John Hyten, told Senate Armed Services Committee members this week that the service has only six bombers that are ready to deploy.

"We have B-1B bombers; this is the workhorse of the Air Force today," Hyten said during his tense confirmation hearing to become vice chairman of the Joint Chiefs of Staff.

"Right now, of all of our B-1 bombers, we have six of them that are fully mission capable: five split between Ellsworth Air Force Base [South Dakota] and Dyess Air Force Base [Texas], one is a test aircraft, 15 B-1s are in depot," he said. "The remaining 39 of 44 B-1s at Ellsworth and at Dyess are down for a variety of discrepancies and inspections."

Looks like the B-21 Raider can't come soon enough.
