Airworthiness Directive · Amendment 39-14936 · Airbus Model A300 Airplanes
Airbus Model A300 Airplanes
This AD applies to Airbus A300 airplanes, all certified models and all serial numbers, certificated in any category, except for:
(1) Airbus Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes, Model A300 B4-605R and B4-622R airplanes, A300 F4-605R and F4-622R airplanes, and Model A300 C4-605R Variant F airplanes.
(2) Airbus Models A300 B4-220, A300 B4-203, and A300 B2-203 airplanes in forward facing crew cockpit certified configuration.
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A300 B2 and B4 series airplanes. That AD currently requires modifying the wiring of the autopilot pitch torque limiter switch. This new AD adds repetitive operational tests of the autopilot disconnection upon pitch override, and related investigative/corrective actions if necessary. This AD results from the determination that such operational tests are necessary following the modification. We are issuing this AD to prevent possible trim loss when the flightcrew tries to override the autopilot pitch control, which could result in uncontrolled flight of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 20 months after August 1, 2005 (the effective date of AD 2005-13-33), modify the wiring of the autopilot pitch torque limiter switch, by doing all of the applicable actions specified in the Accomplishment Instructions of Airbus Service Bulletin A300-22-0117, dated September 7, 2004; Revision 01, dated April 20, 2005; or Revision 02, dated September 14, 2005. After the effective date of this AD, only Revision 02 may be used.
At the applicable time specified in paragraph (g)(1) or (g)(2) of this AD: Do an operational test of the autopilot disconnection upon pitch override, and do all applicable related investigative and corrective actions. Do the actions in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-22-0118, excluding Appendix 01, dated May 18, 2005; except that this AD does not require a report of the inspection results. Do all applicable related investigative and corrective actions before further flight. Repeat the test thereafter at intervals not to exceed 2,000 flight hours.
(1) For airplanes modified before the effective date of this AD in accordance with Airbus Service Bulletin A300-22-0117, dated September 7, 2004: Do the initial test within 2,000 flight hours after the effective date of this AD.
(2) For airplanes modified in accordance with Airbus Service Bulletin A300-22-0117, Revision 01, dated April 20, 2005; or Revision 02, dated September 14, 2005: Do the initial test within 2,000 flight hours after the modification required by paragraph (f) of this AD, or within 2,000 flight hours after the effective date of this AD, whichever occurs later.
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.
