Airworthiness Directive · Amendment 39-13706 · Airbus Model A310 Series Airplanes
Airbus Model A310 Series Airplanes
All Model A310 series airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to all Airbus Model A310 series airplanes, that requires inspecting the pressure-off brakes (POBs) installed on the power control units of the slats and flaps to determine their serial numbers; and replacing any POBs having affected serial numbers with new, serviceable, or modified POBs. This action is necessary to prevent failure of the retaining ring on the POBs, which could result in slat or flap blowback or runaway, with consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
To prevent failure of the retaining ring on the pressure-off brakes (POBs) of the power control units of the slats and flaps, which could result in slat or flap blowback or runaway, with consequent reduced controllability of the airplane, accomplish the following:
(a) Within 18 months after the effective date of this AD: Inspect the identification plates of the POBs installed on the power control units of the slats and flaps to determine the serial numbers of the POBs, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A310-27-2096, Revision 01, dated September 19, 2001.
Note 1: Airbus Service Bulletin A310-27-2096, Revision 01, dated September 19, 2001, refers to Liebherr-Aerospace Lindenberg Service Bulletin 511A0100-27-03, dated November 16, 2000, as the appropriate source for identifying affected serial numbers of POBs, and as an additional source of service information for replacing affected POBs.
(b) For any POB with an affected serial number, as identified in Airbus Service Bulletin A310-27-2096, Revision 01, dated September 19, 2001: Before further flight, replace the POB with a new or serviceable POB that does not have an affected serial number, or with a POB that has been modified per the Accomplishment Instructions of Airbus Service Bulletin A310-27-2096, Revision 01, dated September 19, 2001. Replace the POB per the Accomplishment Instructions of Airbus Service Bulletin A310-27-2096, Revision 01, dated September 19, 2001.
(c) Inspections and replacements accomplished before the effective date of this AD per Airbus Service Bulletin A310-27-2096, dated March 21, 2001, are acceptable for compliance with the corresponding actions required by this AD.
(d) As of the effective date of this AD, no person may install, on any airplane, a POB with a part number and serial number listed in Airbus Service Bulletin A310-27-2096, Revision 01, dated September 19, 2001.
(e) Although the service bulletins referenced in this AD specify to submit certain information and return POBs with affected serial numbers to the POB manufacturer, this AD does not include such a requirement.
(f) In accordance with 14 CFR 39.19, the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, is authorized to approve alternative methods of compliance for this AD.
(g) Unless otherwise specified in this AD, the actions shall be done in accordance with Airbus Service Bulletin A310-27-2096, Revision 01, dated September 19, 2001. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.
