Airworthiness Directive 2013-09-11
recurringAirworthiness Directives; Cessna Aircraft Company Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company Model 500, 501, 550, 551, S550, 560, 560XL, and 650 airplanes. This AD was prompted by multiple reports of smoke and/or fire in the tailcone caused by sparking due to excessive wear of the brushes in the air conditioning (A/C) motor. This AD requires inspecting to determine if certain A/C compressor motors are installed and to determine the accumulated hours on certain A/C drive motor assemblies; repetitive replacement of the brushes in the drive motor assembly, or, as an option to the brush replacement, deactivation of the A/C system and placard installation; and return of replaced brushes to Cessna. We are issuing this AD to prevent the brushes in the A/C motor from wearing down beyond their limits, which could result in the rivet in the brush contacting the commutator causing sparks and consequent fire and/or smoke in the tailcone with no means to detect or extinguish the fire and/or smoke.
Which aircraft AD 2013-09-11 applies to
Serial ranges by model: 500 and 501 S/Ns 0001-0689; 550 and 551 S/Ns 0002-0733 and 0801-1136; S550 S/Ns 0001-0160; 560 S/Ns 0001-0707 and 0751-0815; 560XL S/Ns 5001-5300; 650 S/Ns 0200-0241 and 7001-7119.
Whether AD 2013-09-11 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
