Air Combat Command accident investigators found “clear and compelling evidence” that engine failure led to the crash of a Wisconsin Air National Guard F-16C on June 7 in New Chester, Wisc. “A failure of the power takeoff shaft forward main bearing assembly within the accessory gearbox” caused the crash, according to ACC’s accident investigation board report, issued Wednesday. The F-16, assigned to the 176th Fighter Squadron at Truax Field, took off on a training mission. Approximately one hour and 23 minutes after takeoff, the pilot experienced a sudden loss of thrust. Unable to restart the engine, the pilot ejected, sustaining only minor scratches and bruises. The F-16 impacted near an unoccupied private residence about 57 nautical miles northwest of Truax. Both the aircraft and residence were completely destroyed, according to the report. The aircraft’s value was pegged at $25.7 million. (AIB report; caution, large-sized file.)
The F-47 fighter will be run differently than previous fighter programs and share the same mission systems architecture as the Collaborative Combat Aircraft, Air Force Chief of Staff Gen. David Allvin told the Senate Armed Services Committee. That means advances in one will fuel advances in the other.
