What was found
FOUND BAD CONDENSOR ON MAGNETO, SN 14020225 IN JULY 2014. PART TT APPROXIMATELY 16 HOURS. ON OCTOBER 9, 2015 FOUND BAD CONDENSOR ON WARRANTY REPLACEMENT MAGNETO, SN 14020227, PART TT 184. FAILURES AT 16 AND 184 HOURS ARE UNUSUAL. BECAUSE MAGNETOS ARE OFTEN SOLD IN PAIRS. IT IS POSSIBLE THAT 2 MAGNETOS WITH BAD CONDENSORS COULD BE INSTALLED ON THE SAME AIRPLANE. WITH THIS FAILURE RATE IT IS POSSIBLE THAT BOTH MAGS COULD FAIL ON THE SAME FLIGHT.
