Table 1 to Paragraph ( c ) of this AD—Affected Airplane Models and Serial Numbers (S/Ns) Cessna aircraft company airplane models S/Ns Model 500 and 501 airplanes 0001 through 0689 inclusive. Model 550 and 551 airplanes 0002 through 0733 inclusive, and 0801 through 1136 inclusive. Model S550 airplanes 0001 through 0160 inclusive. Model 560 airplanes 0001 through 0707 inclusive, and 0751 through 0815 inclusive. Model 650 airplanes 0200 through 0241 inclusive, and 7001 through 7119 inclusive.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within 30 days or 10 flight hours after the effective date of this AD, whichever occurs first: Inspect the A/C compressor motor to determine whether P/N FWA1134104-1 or P/N FWA1134104-5 is installed. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the A/C compressor motor can be conclusively determined from that review.
Unsafe condition
This AD was prompted by reports of smoke and/or fire in the tailcone caused by sparking due to excessive wear of the brushes in the A/C motor. 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.
Affected ADs
None.

You just looked this one up by hand
TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
