## Probable cause

An inconsistency between the engines' two N2 sensor signals caused the fuel control to enter a fixed mode, which limited the power available.  Contributing to the accident was the lack of altitude and airspeed available to give the pilot time to select a landing zone, disengage the flight notch, and exercise manual control of the engine after the illumination of the red 'GOV' light.
