Is AD 05-17607 a recurring Airworthiness Directive?

No — AD 05-17607 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 05-17607 apply to?

AD 05-17607 applies to Boeing — models 767. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Boeing Model 757-200 and -300 Series Airplanes and Model 767 Series Airplanes

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757-200 and -300 series airplanes and Model 767 series airplanes. This AD requires replacing the existing operational software of the Pegasus flight management computer (FMC) system with new, improved operational software. This AD results from reports of "old" or expired air traffic control (ATC) clearance messages being displayed on the control display unit (CDU) of the FMC system during subsequent flights. We are issuing this AD to prevent display of "old" or expired ATC clearance messages on the CDU of subsequent flights, which could result in the airplane entering unauthorized airspace or following a flight path that does not provide minimum separation requirements between aircraft, and a consequent near miss or a mid-air collision.

Whether AD 05-17607 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 05-17607 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.
