## Discrepancy

DURING A 100 HOUR INSPECTION, LEAK WAS NOTED ON ACCESSORY DRIVE UNIT.  FURTHER INSPECTION REVEALED THAT THE FEMALE SPLINES IN THE ENGINE WERE WORN TO APPROX 80 PERCENT, SAME AS THE MALE END.  SUGGEST AN ON TIME INSPECTION TO DETERMINE AMOUNT OF WEAR SINCE THERE IS NO SET INSPECTION TIME TO CHECK THIS DRIVE.
