## Discrepancy

THE ACFT FAILED TO START.  UPON INSP, FOUND THE REAR STARTER HSG HAD TWISTED IN RELATION TO THE FRONT HALF OF THE ASSEMBLY.  WE'VE SEEN THIS HAPPEN BEFORE AND IT IS POSSIBLE FOR THE POWER WIRE TO BREAK AND SHORT AGAINST THE STARTER HSG IF THE MOTOR HOUSING TWISTS FAR ENOUGH.  THIS DID NOT HAPPEN IN THIS CASE BUT THE WIRE DID HAVE TENSION ON IT.  CONTACTED THE OPERATOR AND LEARNED THE STARTER WE INSTALLED (S/N FN-160915) HAD FAILED A SHORT TIME LATER AND THAT THEY ALSO HAD ANOTHER ACFT EXPERIENCE THE SAME FAILURE.
