What this AD requires

We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 900EX and FALCON 2000EX airplanes. This AD was prompted by a report of significant fuel leakage at the middle position of the left outboard slat. This AD would require modifying the assembly of the slat extension mechanical stop. We are issuing this AD to prevent failure of the assembly of the slat extension mechanical stop, which if not corrected, could lead to a significant fuel leak and result in an uncontained fire.

FALCON 900EX: serial numbers on which Modification M5281 has been embodied, except those on which Modification M5870 has been embodied in production. FALCON 2000EX: serial numbers on which Modification M2846 has been embodied, except those on which Modification M3678 has been embodied in production.

Whether AD 2016-04-09 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 2016-04-09 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.
