Is AD 2008-05-03 a recurring Airworthiness Directive?

Yes — AD 2008-05-03 requires a repetitive inspection every 6 months. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2008-05-03 apply to?

AD 2008-05-03 applies to Boeing — models 100, 100B, 100B SUD, 200B, 200C, 200F, 300, SP. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Boeing Model 747-100, -100B, -100B SUD, -200B, -200C, -200F, -300, 747SP, and 747SR Series Airplanes Powered by General Electric (GE) CF6-45/50 and Pratt & Whitney (P&W) JT9D-70, JT9D-3 or JT9D-7 Series Engines

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Boeing Model 747-100, -100B, -100B SUD, -200B, -200C, -200F, -300, 747SP, and 747SR series airplanes powered by General Electric (GE) CF6- 45/50 and Pratt & Whitney (P&W) JT9D-70, JT9D-3, or JT9D-7 series engines. This AD requires repetitive inspections to find cracks and broken fasteners of the rear engine mount bulkhead of the inboard and outboard nacelle struts, and repair if necessary. For certain airplanes, this AD mandates a terminating modification for certain inspections of the inboard and outboard nacelle struts. This AD results from reports of web and frame cracks and sheared attachment fasteners on the inboard and outboard nacelle struts. We are issuing this AD to detect and correct cracks and broken fasteners of the inboard and outboard nacelle struts, which could result in possible loss of the rear engine mount bulkhead load path and consequent separation of the engine from the airplane.

Repetitive inspection. Re-inspect every 6 months. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Applies to 747-100/-100B/-100B SUD/-200B/-200C/-200F/-300/747SP/747SR series airplanes powered by General Electric CF6-45/50 or Pratt & Whitney JT9D-70, JT9D-3, or JT9D-7 series engines, as identified in Boeing Alert Service Bulletin 747-54A2202, Revision 1, dated June 22, 2006.

Whether AD 2008-05-03 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 2008-05-03 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.
