Is AD 2007-07-12 a recurring Airworthiness Directive?

No — AD 2007-07-12 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2007-07-12 apply to?

AD 2007-07-12 applies to Honeywell — models NZ-2000, IC-800. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directive 2007-07-12

one-time

Official AD 2007-07-12 · FR doc E7-5896 · 2007-04-03 · appliance

Airworthiness Directives; Honeywell Flight Management Systems (FMSs) Served by Honeywell NZ-2000 Navigation Computers Approved Under Technical Standard Order (TSO) TSO-C115a, and IC-800 Integrated Avionics Computers Approved Under TSOs C9c, C52a, and C115a; as Installed on Various Transport Category Airplanes

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for all Honeywell FMSs served by Honeywell NZ-2000 navigation computers and IC- 800 integrated avionics computers. This AD requires identifying affected computers by part number and software modification level and revising the Limitations section of applicable airplane flight manuals to provide procedures for retaining optimum position determination and intended navigation. This AD results from reports of in-flight unannunciated shifts of computed position in airplanes with the subject flight management system (FMS) computers. We are issuing this AD to prevent a shift in the FMS computed position, which could result in uncommanded deviations from the intended flight path of the airplane and, if those deviations are undetected by the flight crew, compromised terrain/traffic avoidance.

ModelsNZ-2000, IC-800

Applies to Honeywell NZ-2000 navigation computers (TSO-C115a) and IC-800 integrated avionics computers (TSO-C9c, C52a, C115a) as installed on transport category airplanes, including but not limited to Bombardier CL-600-2B16 (CL-601-3A, CL-601-3R, CL-604), Dassault Mystere-Falcon 900, Gulfstream G-1159A/G-IV/GV, Lockheed 382G series, and Raytheon BAe.125 Series 800A (incl. C-29A, U-125) and Hawker 800XP/1000 airplanes.

Whether AD 2007-07-12 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 2007-07-12 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.
