## Discrepancy

(CAN) PROPELLER WAS RECEIVED BY SHOP BECAUSE OF GREASE LEAKAGE AROUND BLADE CLAMPS. UPON DISASSEMBLY TO PERFORM REPAIRS IT WAS NOTICED THAT THE DUST SEAL WAS MISSING FROM THE PROPELLER PISTON ASSEMBLY. SINCE THIS ITEM CAN`T PHYSICALLY FALL OUT IT IS ASSUMED THAT IT WAS INADVERTENTLY LEFT OUT AT A PREVIOUS REPAIR. (TC NR 20070815002)
