Airworthiness Directive · Amendment 39-14299 · Airbus Model A300 B2 and A300 B4 Series Airplanes; Model A300 B4-600, B4-600R and F4-600R Series Airplanes, and Model A300 C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and Model A310-200 and -300 Series Airplanes
Airbus Model A300 B2 and A300 B4 Series Airplanes; Model A300 B4-600, B4-600R and F4-600R Series Airplanes, and Model A300 C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and Model A310-200 and -300 Series Airplanes
This AD applies to all Airbus Model A300 B2-1A, B2-1C, B2K-3C, and B2-203 and A300 B4-2C, B4-103, and B4-203 airplanes; Model A300 B4-601, B4-603, B4-620, and B4-622, A300 B4-605R and B4-622R, A300 F4-605R and F4-622R, and A300 C4-605R Variant F airplanes; and Model A310-203, -204, -221, and -222 and -304, -322, -324, and -325 airplanes; certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all the Airbus models identified above. This AD requires modifying the electrical power supply logic for the integral lighting of the standby horizon indicator in the cockpit, accomplishing repetitive operational tests of the integral lighting logic system, and performing corrective action if necessary. This AD is prompted by a report of temporary loss of six cathode ray tube (CRT) flight displays and the integral lighting of the standby horizon indicator backlight in the cockpit during takeoff, due to failure of the normal electrical power circuit. That power circuit supplies power to both the CRTs and the standby horizon indicator backlight. We are issuing this AD to prevent loss of the integral lighting due to failure of the normal electrical power circuit, which could result in inability of the pilot to read the backup attitude information during takeoff, and possible deviation from the intended flight path.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Unless otherwise specified in this AD, the term “service bulletin,” as used in this AD, means the Accomplishment Instructions of the applicable service bulletin identified in Table 1 of this AD. Airbus Service Bulletins A300-33-0126, A300-33-6049, and A310-33-2047 specify to submit certain information to the manufacturer, but this AD does not include that requirement.

For airplanes on which Airbus Modifications 12513 and 12730 have not been accomplished: Within 18 months after the effective date of this AD, modify the electrical power supply logic of the integral lighting for the standby horizon indicator in the cockpit in accordance with the service bulletin.
For all airplanes: Within 700 flight hours after accomplishing the modification required by paragraph (g) of this AD, or within 700 flight hours after the effective date of this AD, whichever is later, accomplish the operational test of the integral lighting logic system in accordance with the service bulletin. Repeat the test thereafter at intervals not to exceed 700 flight hours.
(i) If any operational test required by paragraph (h) of this AD fails: Before further flight, accomplish any applicable repair per a method approved by either the Manager, International Branch, ANM-116, FAA, Transport Airplane Directorate; or the Direction Générale de l'Aviation Civile (DGAC) (or its delegated agent). Airbus A300-600 and A310 Trouble Shooting Manuals; Airbus A300-600 and A310 Aircraft Wiring Manuals; and Airbus A300-600 and A310 Aircraft Maintenance Manuals, are approved methods for accomplishing the repair, as applicable. Except, in the case of a failed test in which standard maintenance practices do not solve the problem, a repair approved by the FAA or the DGAC is required.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
