What was found
PILOTS ASSUMED THAT THE PITCH TRIM SYSTEM WAS IN A FAILED STATE WHEN PITCH TRIM INDICATION STARTED TO INDICATE NO MOVEMENT. THE STICKING SECTION OF THE INDICATION CAUSED MORE CONFUSION DUE TO THE FACT THAT THE YOKE COMING OVER CENTER AND FALLING INTO THE PILOTS LAP HAPPENS AT THE SAME TIME THAT THE INDICATION JUMPED ONCE COMING FREE. PILOTS CONCLUDED THAT THE SYSTEM WAS FAILED IN PRIMARY AND SECONDARY MOTORS BECAUSE THE INDICATION ACTED THE SAME IN BOTH PRI AND SEC MODES.
