## Discrepancy

DURING ROUTINE MX, ONE OF OUR TECHNICIANS WAS TASKED TO TAKE A SOAP SAMPLE FROM THE ACFT APU.  WHILE TAKING THE SAMPLE HE NOTICED THE APU STARTER GEN WAS LOOSE.  AFTER FURTHER INVESTIGATION HE FOUND THE CLAMP THAT SECURES THE STARTER GEN TO THE APU WAS SAFETIED, BUT DID NOT ENGAGE THE FLANGE OF THE STARTER GEN.  THE CLAMP WAS ENGAGED TO THE ADAPTER FLANGE ON THE APU ONLY.  THIS RESULTED IN DAMAGE TO THE STARTER GEN DRIVE SHAFT SPLINES & APU INTERNAL GEARS.
