The short circuit of the C321capacitor in the Electronic Control Unit (ECU) that resulted in a single-point failure of the ECU's -15V power supply which disengaged/reverted the Hydro-mechanical Unit (HMU) from automatic to manual fuel control. Factors contributing to the accident were the pilot's attempted remedial actions in the manual mode that resulted in the engine over temperature and loss of power, and the lack of suitable terrain for the forced landing.
