What was found
T-BAR ON CYCLIC CONTROL IS RETAINED WITH A NUT AND COTTER PIN. THE NUT, WASHER AND COTTER PIN WERE NEVER INSTALLED AT THE FACTORY. THE THREADED PORTION STILL HAD MASKING TAPE ON THE THREADS. THE T-BAR PULLED OUT OF THE CYCLIC IN-FLIGHT AND COULD VERY EASILY HAVE RESULTED IN CATASTROPHE.
