The accident investigation board report on the November 2012 crash of an F-22 Raptor at Tyndall AFB, Florida, was released by Air Combat Command on 9 August 2013. The cause of the accident was a chaffed wire that arced, burned through a hydraulic line, and caused the generator to go offline. When the pilot attempted to restart the generator, the ensuing arc ignited misting hydraulic fluid and started a fire. The fire compromised systems that control the flight control surfaces, which led to an unrecoverable situation. Weather was cited as a contributing cause. The aircraft (Air Force serial number 00-4013) was assigned to the 43rd Fighter Squadron at Tyndall, the F-22 training unit. The pilot ejected safely.
