Airworthiness Directive 97-13-04

What this AD requires
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A300-B2 and -B4 series airplanes, that currently requires an inspection to detect discrepancies of a certain thrust reverser control lever spring; an operational test to verify the integrity of the flight inhibition circuit of the thrust reverser system; and either the correction of discrepancies or deactivation of the associated thrust reverser. That AD also provides for an optional terminating action. That AD was prompted by a report that, due to broken and deformed thrust reverser control lever springs, an uncommanded movement of the thrust reverser lever to the unlock position and a ``reverser unlock'' amber warning occurred on one airplane. The actions specified by that AD are intended to detect such broken or deformed control lever springs before they lead to uncommanded deployment of a thrust reverser and consequent reduced controllability of the airplane. This amendment requires installation of the previously optional terminating action in accordance with the latest service information.
Which aircraft AD 97-13-04 applies to
Applies to airplanes identified in the preceding applicability provision equipped with thrust reverser control lever spring P/N A2791294520000; restates AD 96-04-05 inspection/replacement (spring, relay P/N 125GB or 124GB, wiring) per Airbus All Operators Telex 78-03, Revision 1, and adds a new requirement to replace the control levers with new springs per Airbus Service Bulletin A300-78-0015, Revision 2.
Whether AD 97-13-04 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.
