## Discrepancy

(CAN) THE INPUT GEARBOX CAN BE USED ON NR 1 OR NR 2 POSITION.  WHEN USED ON NR 2 POSITION THE CHIP DETECTOR LOCATION IS PLUGGED.  THE PLUG WAS FITTED WITH AN O-RING. DURING GROUND RUNS, A SMALL WEEP WAS NOTED BUT NOTHING SERIOUS OR ALARMING.  AFTER TEST FLIGHTS THE O-RING WAS SCHEDULE TO BE REPLACED AND DURING RE-ASSEMBLY IT WAS NOTICED THAT THE HOUSING ITSELF WAS CRACKED. MFG WAS NOTIFIED AND UNIT SCHEDULED FOR REPLACEMENT.
