Airworthiness Directives; Dornier Model 328-100 and Model 328-300 Series Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 and Model 328-300 series airplanes, that requires repetitive detailed inspections of all attach caps of the passenger seats for cracks or defects; and replacement of the caps with new caps, if necessary. This action is necessary to prevent failure due to cracking of the seat frame attach caps on the passenger seat assemblies, which could result in separation of the passenger seat from the supporting structure during an emergency landing, hard landing, or turbulence, and consequent injury to the seat occupant. This action is intended to address the identified unsafe condition.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Whether AD 04-9763 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 04-9763 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.
