Airworthiness Directive · Amendment 39-11522 · Airbus Model A300, A300-600, and A310 Series Airplanes
Airbus Model A300, A300-600, and A310 Series Airplanes
Superseded. A later AD replaced this one: AD 2000-23-07. Comply with the one in force.
Airbus Model A300 series airplanes, having manufacturer's serial number 159, 168, 188, 202, 205, 213, 299, or 302; and all Model A300-600 and A310 series airplanes; certificated in any category.
Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (c) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Airbus Model A300 and all Model A300-600 and A310 series airplanes. This action requires performing a pitch trim system test to detect any continuity defect in the autotrim function, and follow-on corrective actions, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent a sudden change in pitch due to an out- of-trim condition combined with an autopilot disconnect, which could result in reduced controllability of the airplane.
To prevent a sudden change in pitch due to an out-of-trim condition combined with an autopilot disconnect, which could result in reduced controllability of the airplane, accomplish the following:
(a) Within 20 days after the effective date of this AD: Perform a pitch trim system test to detect any continuity defect in the autotrim function, in accordance with All Operators Telex (AOT) A300-22A0115 (for Model A300 series airplanes), A300-600-22A6042 (for Model A300-600 series airplanes), or A310-22A2053 (for Model A310 series airplanes), all dated December 23, 1999, as applicable.
(1) If no continuity defect is found, no further action is required by this paragraph.
(2) If any continuity defect is found, prior to further flight, accomplish the actions required by paragraphs (a)(2)(i) and (a)(2)(ii) of this AD, in accordance with the applicable AOT.
(i) Repair any discrepant wiring found in the pitch trim system.
(ii) Repeat the initial pitch trim system test required by paragraph (a) of this AD.
Note 2: All Operators Telexes (AOT) A300-22A0115, A300-600-22A6042, and A310-22A2053, all dated December 23, 1999, reference Aircraft Schematic Manual (ASM) 22-27-00 as an additional source of service information to accomplish the repair.
(b) Within 10 days after accomplishing the pitch trim system test required by this AD, or within 10 days after the effective date of this AD, whichever occurs later: Submit a report of the inspection results (both positive and negative findings) to Airbus Customer Services, Engineering and Technical Support, Attention Mr. Vincent Frayssinet, AI/SE-E43; phone number 33 (0)5.62.11.04.96; Sita Code TLSBQ7X.
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.
