## Discrepancy

(CAN)  WHILE DOING A 100 HOUR INSPECTION ON THE BELL 205A-1, THE TAIL ROTOR DRIVE SHAFT ASSEMBLY WAS FOUND SCORED BEYOND LIMITS. THE INSPECTION IS A CLEARANCE CHECK BETWEEN THE T/R DRIVE SHAFT COVER AND THE T/R DRIVE SHAFT. THIS CLEARANCE CHECK IS DUE TO POSSIBLE DAMAGE TO THE T/R DRIVE SHAFT COVER (GETTING DENTED DUE TO THE WEIGHT OF THE T/R DRIVE SHAFT) BY THE INSTALLATION OR REMOVAL OF THE STARTER GENERATOR. THE STARTER GEN IS POSITIONED JUST ABOVE THE T/R DRIVE SHAFT COVER. THE STARTER GEN WAS REMOVED AND REINSTALLED 25 HOURS PREVIOUSLY TO THIS 100 HOUR INSPECTION. AD 92-27-21 REGARDING THIS SUBJECT WAS CARRIED OUT AT THE REMOVAL AND INSTALLATION OF THE STARTER GEN.
