## Discrepancy

FOUND DURING A 500HR MAG AND IMPULSE COUPLING INSPECTION, A DEFECTIVE DISTRIBUTOR GEAR FINGER.  THIS FINGER HAD WORKED LOOSE FROM ITS PLASTIC SEAT ALLOWING SOME MOVEMENT BOTH SIDE TO SIDE AS WELL AS UP AND DOWN THE SHAFT.  PARTS WERE STILL FUNCTIONING WHEN DISCOVERED.  THIS WAS A PROBLEM FOR BOTH THE LT AND RT MAGS OF THE SAME ENGINE.
