Irreversible engine failure caused the crash of an MQ-1B Predator April 14, 2012, into an unpopulated mountainside in Afghanistan, according to an Air Combat Command Abbreviated Accident Investigation Board report released today.

The mishap crew was assigned to the 162nd Reconnaissance Squadron, Springfield Air National Guard Base, Ohio. When the accident occurred, the mishap crew was flying a mission in support of Operation Enduring Freedom.

According to the report, the mishap remotely piloted aircraft experienced a single-point failure that simultaneously caused both ignition circuits to lose the ability to control engine ignitions. Based on mission data logs, the AAIB Board President believes a substantially contributing factor to the failure of the ignition control system was a failure of the power cable that was the only point on this particular MQ-1B that joined the two ignition circuits.
