What was found
DURING ANNUAL INSPECTION, PROPELLER COUNTERWEIGHT ATTACH BOLTS FOUND UNSAFTIED POST OVERHAUL. HARTZELL MANUAL NR 117D REQUIRES THESE BOLTS TO BE REPLACED AT OVERHAUL AND RE-DRILLED FOR ROLL-PIN SAFETY. THESE BOLTS WERE RE-USED AFTER OVERHAUL SINCE THEY WERE DRILLED IN A LOCATION WHICH COULD NOT BE SAFTIED WITH A ROLL-PIN.
