HE ALSO STATED THAT AFTER ABOUT 90 DEG THROUGH THE TURN, THE AIRCRAFT LOST POWER, STALLED AND CRASHED. DURING AN INVESTIGATION, THE MAIN FUEL CONTROL VALVE WAS FOUND TO BE ABOUT 75% CLOSED. THE CABLE ASSEMBLY, PN 65227-06, THAT CONNECTS THE CONTROL KNOB IN THE COCKPIT TO THE MAIN FUEL CONTROL VALVE WAS DISCONNECTED FROM THE FUEL CONTROL VALVE BRACKET, PN 64304-00.
