## Discrepancy

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.
