Is AD 98-6333 a recurring Airworthiness Directive?

No — AD 98-6333 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 98-6333 apply to?

AD 98-6333 applies to Airbus — models A300-600, A310. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Airbus Model A300, A310, and A300-600 Series Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300, A310, and A300-600 series airplanes, that requires inspections to detect defects of the flanges of the bleed air ducts of the auxiliary power unit (APU), and to measure the material thickness of the flanges; and repair, replacement of the duct with a new or serviceable duct, or operation of the airplane with the bleed air system of the APU inoperative, if necessary. For certain airplanes, the amendment also requires an inspection to detect cracks of the flanges, and follow-on actions. This amendment is prompted by issuance of mandatory continued airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent rupturing and cracking of the flanges of the bleed air ducts, which could damage the elevator control system and consequently reduce the controllability of the airplane.

Whether AD 98-6333 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 98-6333 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.
