Is AD 96-591 a recurring Airworthiness Directive?

Yes — AD 96-591 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 96-591 apply to?

AD 96-591 applies to Airbus — models A300-600. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) T96-01-52 that was sent previously to all known U.S. owners and operators of Airbus Model A310 and A300-600 series airplanes by individual telegrams. Among other things, this AD requires repetitive inspections to ensure correct synchronization of the hydraulic control valves of the trimmable horizontal stabilizer (THS) actuator; replacement of the horizontal stabilizer actuator motors with new or serviceable motors and resynchronization of the valves, or adjustment of the synchronization, if necessary; and a functional test of the THS. This amendment is prompted by a report of desynchronization of the hydraulic control valves that direct fluid to the horizontal stabilizer actuator motors, which resulted in uncommanded movement of the THS. The actions specified by this AD are intended to prevent such desynchronization, which could lead to runaway of the horizontal stabilizer to its full up or down position, subsequent reduced maneuvering capability, and potential pitch upset.

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.

applicability derived from the AD summary — confirm the model/serial from the records

Whether AD 96-591 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.

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.
