What was found
DURING A AIRWORTHNESS CHECK, THE MECHANIC INSPECTED THE TAIL ROTOR AND WHEN HE MOVED THE TAIL ROTOR IN ANY WAY (FLEXING THE SPAR), HE HEARD A CRACKLING NOISE THAT WARRANTED FURTHER INSPECTION. AFTER DISASSEMBING THE TAIL ROTOR TO INSPECT THE SPAR, A CRACK WAS FOUND ON THE SPAR. THE TAIL ROTOR/BLADE ASSEMBLY WAS REMOVED AND REPLACED WITH A SERVICEABLE ASSEMBLY. THIS AIRCRAFT HAS NOW RETURNED TO SERVICE.
