Is AD 98-1970 a recurring Airworthiness Directive?

No — AD 98-1970 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 98-1970 apply to?

AD 98-1970 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), applicable to certain Airbus Model A330 and A340 series airplanes. This action requires revising the Airplane Flight Manual (AFM) to prohibit use of the autobrake during landing on contaminated runways. This action also requires replacement of the brake and steering control unit (BSCU) with a new BSCU, which eliminates the need for the AFM revision. For certain airplanes, this action also requires installation of new brakes. This amendment is prompted by the issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent insufficient braking capability, which could increase the potential for landing overrun.

Whether AD 98-1970 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 98-1970 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.
