Pratt & Whitney says all new F135 engines it is now delivering come with the vibration fix already installed. The affected F-35s could be back in the air in one to two weeks. As of Sunday, 24 of the 90 KC-135s that were inspected had noncompliant pins, the Air Force said. A faulty fan disk failed during ground maintenance, investigators said. What if you could predict the effects of one deployment three years into the future? Officials estimate those initiatives have saved hundreds of millions of dollars, increased vehicle availability and cut time at work. “Ultimately, the [Lightning Technician Program] concept did not meet the needs of the Air Force enterprise,” the service said. Col. Jay Bertsch lasted four months as commander of the 8th Maintenance Group at Kunsan Air Base, South Korea. The Air Force is finding workarounds to keep carrying out mobility missions while many C-130Hs are grounded due to concerns over propeller assembly cracks. It's uncertain how long it will take Air Mobility Command to replace all the defective propeller assemblies that have grounded most C-130H planes. Load More
