Airworthiness Directive 96-12-13
one-timeAirworthiness Directives; Dornier Model 328 Series Airplanes Equipped with Honeywell GP-300 Guidance and Display Controller
What this AD requires
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Dornier Model 328 series airplanes. This action requires modification of certain Honeywell GP-300 guidance and display controllers. This amendment is prompted by reports of smoke and fumes, due to a defective light bulb, emitting from the Honeywell GP- 300 guidance and display controller; and a report of failure of the autopilot to disconnect manually. The actions specified in 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.
Which aircraft AD 96-12-13 applies to
Extracted text begins at the standard 'preceding applicability provision' boilerplate; the AD's actual airplane model list precedes this excerpt and was not captured by extraction. Applies to Honeywell GP-300 guidance and display controllers having P/N 7015327-901 or -902, to be modified per Honeywell Service Bulletin 7015327-22-2 dated March 4, 1996.
Whether AD 96-12-13 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:
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.
