Is AD 99-25932 a recurring Airworthiness Directive?

Yes — AD 99-25932 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 99-25932 apply to?

AD 99-25932 applies to Mcdonnell Douglas — models KC-10A. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; McDonnell Douglas Model DC-10-10, -15, and -30 Airplanes, and KC-10A (Military) Airplanes

What this AD requires

This amendment revises an existing airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-10-10, -15, and -30 airplanes, and KC-10A (military) airplanes, that currently requires inspections to determine the condition of the lockwires on the forward engine mount bolts and correction of any discrepancies found. That amendment also provides for termination of the inspections for some airplanes by installing retainers on the bolts. That AD was prompted by reports of stretched or broken lockwires on the forward engine mount bolts. The actions specified by that AD are intended to prevent broken lockwires, which could result in loosening of the engine mount bolts, and subsequent separation of the engine from the airplane. This amendment provides an additional optional terminating modification and clarification of the requirements of the previous optional terminating modification, and removes the reporting requirements for the repetitive inspections.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Whether AD 99-25932 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.

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.
