Is AD 01-21105 a recurring Airworthiness Directive?

No — AD 01-21105 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 01-21105 apply to?

AD 01-21105 applies to Airbus — models A340. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Airbus Model A330 and A340 Series Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to all Airbus Model A330 and A340 series airplanes. This action requires a one-time inspection to detect cracking of the bogie beams of the main landing gear (MLG), and follow-on actions, if necessary. This action is necessary to detect and correct cracking of the MLG bogie beams, which could result in failure of the beams and consequent loss of the landing gear wheels and brakes, and structural damage to the MLG strut and airframe. This action is intended to address the identified unsafe condition.

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

Whether AD 01-21105 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 01-21105 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.
