AD 2017-01-05 Airworthiness Directives; Airbus Defense and Space S.A. (Formerly Known as Construcciones Aeronauticas, S.A.) Airplanes
Models named: CN-235, CN-235-100, CN-235-200, CN-235-300. 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, 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 compliance time specified in table 1 to paragraph (g) of this AD, and thereafter at intervals not to exceed the values specified in table 2 to paragraph (g) of this AD, as applicable to airplane model, accomplish the inspections as specified in paragraphs (g)(1) and (g)(2) of this AD, in accordance with the instructions of Airbus Defense and Space Alert Operators Transmission (AOT) AOT-CN235-53-0002, Revision 1, dated September 17, 2015. (1) A special detailed inspection for cracks and other discrepancies with a borescope of the rear fuselage lateral beam between frame (FR) 31 and FR 45, left-hand (LH) and right-hand (RH) side. (2) A detailed visual inspection for cracks and other discrepancies of the external area of the rear fuselage lateral beam, LH and RH side. Table 1 to Paragraph ( g ) of This AD—Initial Inspection Compliance Time A or B, whichever occurs later A Before exceeding 15,000 flight cycles or 15,000 flight hours, whichever occurs first since airplane first flight. B Within 50 flight cycles or 50 flight hours, whichever occurs first after the effective date of this AD. Table 2 to Paragraph ( g ) of This AD—Repetitive Inspection Intervals Airplane models Repetitive interval (whichever occurs first, flight cycles or flight hours) Model CN-235 and CN-235-100 airplanes 3,600 flight cycles or 3,100 flight hours. Model CN-235-200 airplanes 3,600 flight cycles or 2,800 flight hours. Model CN-235-300 airplanes 15,000 flight cycles or 15,000 flight hours.
Unsafe condition
This AD was prompted by reports of cracks in certain areas of the rear fuselage. We are issuing this AD to detect and correct cracks in the rear fuselage lateral beam and its external area; such cracking could lead to failure of the affected components, and result in reduced structural integrity of the fuselage.
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.
