Is AD 05-14684 a recurring Airworthiness Directive?

No — AD 05-14684 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 05-14684 apply to?

AD 05-14684 applies to Mcdonnell Douglas — models DC-8-12, DC-8-21, DC-8-31, DC-8-32, DC-8-33, DC-8-41, DC-8-42, DC-8-43. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; McDonnell Douglas Model DC-8-11, DC-8-12, DC-8-21, DC-8-31, DC-8-32, DC-8-33, DC-8-41, DC-8-42, DC-8-43, DC-8F-54, and DC-8F-55 Airplanes; and DC-8-50, DC-8-60, DC-8-60F, DC-8-70, and DC-8-70F Series Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas airplane models. This AD requires a one-time test to determine the material of the upper inboard spar cap of the wing, and corrective actions if necessary. This action is necessary to prevent stress corrosion cracking in the forward tang of the upper inboard spar cap of the wing, which could result in structural damage to adjacent components of the wing and consequent reduced structural integrity of the airplane. This action is intended to address the identified unsafe condition.

Whether AD 05-14684 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 05-14684 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.
