Is AD E7-1204 a recurring Airworthiness Directive?

No — AD E7-1204 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD E7-1204 apply to?

AD E7-1204 applies to Dassault — models 900. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Dassault Model Mystere-Falcon 50 and 900, and Falcon 900EX airplanes; and Model Falcon 2000 and Falcon 2000EX airplanes. This AD requires an inspection of the identification plates of the outboard slats to determine the type of identification plates and the part numbers. For certain airplanes, this AD also requires a revision to the Limitations and Normal Procedures sections of the airplane flight manual to provide procedures for operation in icing conditions; and replacement of the anti-icing manifold with an anti-icing manifold of the correct type design if necessary. For certain airplanes, this AD also requires related investigative and corrective actions if necessary. This AD results from a finding that the outboard slats for Model Mystere-Falcon 50 airplanes have been erroneously authorized, in limited cases, as interchangeable for use on Model Mystere-Falcon 900 and Falcon 900EX airplanes; and Model Falcon 2000 and Falcon 2000EX airplanes. We are issuing this AD to prevent failure of the anti-icing manifold of the outboard slats, which could result in loss of control of the airplane.

Whether AD E7-1204 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 E7-1204 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.
