What was found
DURING ANNUAL INSPECTION, IT WAS FOUND THAT FEATHERING PIN ASSY MOUNTED ON THIS PROPELLER IS WRONG PART. PART AS INSTALLED IS MOUNTED ON TOP OF TWO RIVETS IN SPINNER BULKHEAD, CAUSING PART TO BE BENT OVER THE RIVETS AND WEARING ON BLADE CLAMPS. LEFT UNREPAIRED IT COULD SERIOUSLY COMPROMISE INTEGRITY OF THE BLADE CLAMP OR LATCH ASSY COULD FINALLY BREAK DUE TO STRESS. LATCH ASSY SHOULD HAVE CAST INTO ASSY, STAND-OFFS ON BOTTOM TO GIVE CLEARANCE FOR RIVETS. CORRECT ASSY SHOULD ALSO HAVE INDENTIONS CAST INTO MOUNTING POINTS TO GIVE CLEARANCE FOR PROP FLANGE MOUNTING BOLTS. ASSY AS MOUNTED HAS BEEN FORCED INTO POSITION AND PROP MOUNTING BOLTS HAVE LEFT THREAD GOUGES WHERE BOLT WAS FORCED PAST ASSY.
