## Discrepancy

TCM/BENDIX MAGNETO IMPULSE COUPLING SPRING. P/N 10-51324, PART TSN 11.6 HOURS INSTALLED ON: MAGNETO P/N 10-349350-5. S/N E189909FR M/N S6RN-1225 MAGNETO TSN   11.6 HOURS. THIS SPRING BROKE APPROXIMATELY 6 INCHES FROM THE OUTER DIAMETER END.  THE MECHANIC REMOVED THE MAG BECAUSE HE HEARD NO COUPLING ENGAGEMENT.  I DO NOT KNOW THE RESULTS OF THE MAG DROP TEST, PERHAPS THEY NEVER GOT THAT FAR.  I WOULD GUESS IT WAS ROUGH.  THE BREAK IN THE SPRING LOOKS LIKE A METALLURGY PROBLEM.  IT IS A CLEAN BREAK WITH A BIT OF A FLASHING ON ONE SIDE.
