Is AD 2004-14-17 a recurring Airworthiness Directive?

No — AD 2004-14-17 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2004-14-17 apply to?

AD 2004-14-17 applies to Airbus — models A310, A300-600, A300. Serial/part conditions may narrow it to specific aircraft.

Official AD 2004-14-17 · FR doc 04-15514 · 2004-07-13 · airframe

Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and F4-600R (Collectively Called A300-600) Series Airplanes; and Model A310 Series Airplanes; Equipped With Pratt & Whitney JT9D-7R4 or 4000 Series Engines

What this AD requires

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A300-600 and A310 series airplanes, that currently requires deactivating both thrust reversers and revising the airplane flight manual (AFM) to ensure safe and appropriate performance during certain takeoff conditions. This amendment requires installing modifications that will add an independent third line of defense on the thrust reversers, which would enhance their redundancy and terminate the requirements of the existing AD. The actions specified by this AD are intended to prevent in-flight deployment of the thrust reversers, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.

ModelsA310, A300-600, A300

Restates/supersedes AD 98-25-51 requiring deactivation of both thrust reversers (per Airbus AOT 78-08) on A310 and A300-600 series airplanes; new requirement in this AD adds installation of an independent third line of defense (synchronous shaft lock system plus a new electrical circuit) per applicable Airbus service bulletin, after which thrust reversers may be reactivated and the AFM limitation removed.

Whether AD 2004-14-17 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 2004-14-17 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.
