What was found
DURING 100 HUR INSPECTION, FOUND A RETAINING RING MISSING. THE RING SECURES A BELLCRANK TO THE CYCLIC SHAFT ASSEMBLY. THIS ALLOWED THE BELLCRANK TO SHIFT UP AND DOWN ON THE SHAFT APPROX 0.5 INCH. WHEN THE BELLCRANK SHIFTS UP IT CONTACTS BRACKET PN L671M 1005240 WHICH PREVENTS THE BELLCRANK FROM COMMING OFF OF THE SHAFT.
