Models named: CN-235, CN-235-100, CN-235-200, CN-235-300, C-295. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Airbus Defense and Space S.A. (formerly known as Construcciones Aeronauticas, S.A.) Model CN-235, CN-235-100, CN-235-200, and CN-235-300 airplanes; and Model C-295 airplanes; certificated in any category, all manufacturer serial numbers.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within the applicable compliance time defined in paragraph (g)(1) or (g)(2) of this AD: Do an initial general visual inspection of each motorized fuel valve having part number (P/N) 7923227F for the presence of fuel on the electrical connectors and inside the receptacles, in accordance with the instructions of Airbus Defense and Space Alert Operators Transmission (AOT) AOT-CN235-28-0001, Revision 1; or Airbus Defense and Space AOT AOT-C295-28-0001, Revision 1, both dated September 27, 2016, as applicable. Repeat the inspection thereafter at intervals not to exceed 300 flight hours. (1) For airplanes that, as of the effective date of this AD, have accumulated 6,000 flight cycles or more since first flight of the airplane: Do the inspection within 30 flight cycles or 30 days after the effective date of this AD, whichever occurs first. (2) For airplanes that, as of the effective date of this AD, have accumulated less than 6,000 flight cycles since first flight of the airplane: Do the inspection within 300 flight hours or 30 days after the effective date of this AD, whichever occurs later.
Unsafe condition
This AD was prompted by leakage of a motorized cross-feed fuel valve, which was detected during accomplishment of a functional check. We are issuing this AD to detect and correct leaks in a motorized fuel valve, which could lead to failure of the fuel valve and consequent improper fuel system functioning or, in case of the presence of an ignition source, an airplane fire.
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.
