This proposed AD was prompted by reports of smoke and/or fire in the tailcone caused by brushes wearing beyond their limits on the A/C motor. This proposed AD would require inspection of the number of hours on the A/C compressor hour meter, inspection of the logbook, and replacement of the brushes on certain P/N A/C compressor motors or deactivation of the A/C system until replacement of the brushes.
