Airworthiness Directives; Airbus Model A340-541 and -642 Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: * * * * * * * * [S]ome Allowable Damage Limits and Repairs published in SRM Chapters 57-61-12 PB101 and 57-61-12 PB201 were de-validated starting from the SRM revision issued on January 2009. The terminology "De-validated SRM" used in this AD text refers to the SRM chapters mentioned above. In order to prevent complete inner aileron split due to possible failure or disbonding of the repairs on the inner aileron panels performed as per "devalidated SRM", which may result in flutter coupling of the free aileron part, this AD requires a one time inspection of the inner aileron panels to identify the presence of "de-validated SRM" repairs and, if necessary, to apply the associated corrective actions [repair].

Whether AD 2011-09-01 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:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 2011-09-01 complied with on your aircraft?

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
