That NPRM proposed to 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 and also require reporting of aircraft information related to the replacement of the brushes. That NPRM was prompted by reports of smoke and/or fire in the tailcone caused by brushes wearing beyond their limits on the A/C motor.

That NPRM proposed to 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 and also require reporting of aircraft information related to the replacement of the brushes.

We must receive comments on this supplemental NPRM by January 22, 2013.
