Airworthiness Directives; Dornier Model 328 Series Airplanes Equipped With Honeywell GP-300 Guidance and Display Controller

What this AD requires

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Dornier Model 328 series airplanes, that currently requires modification of certain Honeywell GP-300 guidance and display controllers. That AD was prompted by reports of smoke and fumes emitting from the Honeywell GP-300 guidance and display controller due to a defective light bulb; and a report of failure of the autopilot to disconnect manually. The actions specified by this AD are intended to prevent a defective light bulb from causing a short circuit that emits smoke and fumes into the cockpit; or causing damage to the circuit cards and various components, which may lock the autopilot into the engaged mode. Locking of the autopilot into the engaged mode could lead to the inability of the pilot to disconnect the autopilot, which could result in reduced controllability of the airplane. This amendment requires verification of proper installation of the modification, and repair, if necessary.

Part-conditional — 7015327-901, 7015327-902.

Applies to airplanes equipped with a Honeywell GP-300 guidance and display controller having P/N 7015327-901 or -902; requires wiring re-test/repair per Honeywell SB 7015327-22-4 (restates modification requirement of AD 96-12-13 via SB 7015327-22-2).

Whether AD 2001-26-14 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 2001-26-14 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.
