## Discrepancy

DURING POST FLIGHT,  MECHANIC FOUND A DING IN THE LEADING EDGE OF 1 TAIL ROTOR BLADE. FURTHER INSPECTION REVEALED A BROKEN STABILIZER BOLT HEAD. TRB WAS REPLACED. AIRCRAFT MANUFACTURE WAS CONTACTED FOR AN DER APPROVED REPAIR. AFTER AUTHORIZED REPAIR WAS PERFORMED AIRCRAFT WAS FLOWN ON A FERRY PERMIT TO MAINTENANCE BASE. AIRCRAFT MANUFACTURE IS CONDUCTING AN INVESTIGATION AS TO WHY THE BOLT BROKE. FURTHER INFO WILL BE SUPPLIED AS IT BECOMES AVAILABLE. A SEPARATE REPORT WILL BE MADE TO THE NTSB FOR SECONDARY TRB DAMAGE.
