Is AD 00-2403 a recurring Airworthiness Directive?

No — AD 00-2403 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 00-2403 apply to?

AD 00-2403 applies to Airbus — models A320, A321. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Airbus Model A319, A320, and A321 Series Airplanes

What this AD requires

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A319, A320, and A321 series airplanes, that currently requires relocation of the engine/master 1 relay from relay box 103VU to shelf 95VU in the avionics bay. This amendment continues to require the relocation using new electrical contacts, and, for certain airplanes, adds a requirement to replace certain contacts installed in shelf 95VU during relocation of the relay with new contacts. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent a simultaneous cutoff of the fuel supply to both engines, which could result in a loss of engine power and consequent reduced controllability of the airplane.

Whether AD 00-2403 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 00-2403 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.
