Summary
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
An A300-600 operator reported a recent event which occurred during the take-off roll, where a SOGERMA co-pilot seat slid back uncommanded to the end position. The seat horizontal movement actuator was replaced on the affected co-pilot seat. At the following take-off roll the same event occurred, the co-pilot seat sliding back uncommanded again. * * *
An unwanted movement of pilot or co-pilot seat in the horizontal direction is considered as potentially unsafe, especially during the take-off phase when the speed of the aeroplane is greater than 100 knots and until landing gear retraction.
The airworthiness directive
2009-11-09 Airbus: Amendment 39-15919. Docket No. FAA-2009-0486; Directorate Identifier 2009-NM-064-AD.
(a) Effective Date
PDF page 2(a) This airworthiness directive (AD) becomes effective June 12, 2009.
(b) Affected ADs
PDF page 2(b) None.
(c) Applicability
PDF page 2(c) This AD applies to Airbus Model A310-203, A310-204, A310-221, A310-222, A310-304, A310-322, A310-324, and A310-325 airplanes; and Airbus Model A300 B4-601, A300 B4-603, A300 B4-605R, A300 B4-620, A300 B4-622, A300 B4-622R, A300 C4-605R Variant F, A300 F4-605R and A300 F4-622R airplanes; certificated in any category; all serial numbers having SOGERMA 2510112 series pilot electrical seats or SOGERMA 2510113 series co-pilot electrical seats installed.
(d) Subject
PDF page 3(d) Air Transport Association (ATA) of America Code 25: Equipment/Furnishings.
(e) Reason
PDF page 3(e) The mandatory continued airworthiness information (MCAI) states:
An A300-600 operator reported a recent event which occurred during the take-off roll, where a SOGERMA co-pilot seat slid back uncommanded to the end position. The seat horizontal movement actuator was replaced on the affected co-pilot seat. At the following take-off roll the same event occurred, the co-pilot seat sliding back uncommanded again. Further to these events, the inspection carried out on the two removed actuators ARTUS Part Number (P/N) RT19H4FX, revealed that the clutch was broken inside the shaft, thus unlocking the seat horizontal movement.
An unwanted movement of pilot or co-pilot seat in the horizontal direction is considered as potentially unsafe, especially during the take-off phase when the speed of the aeroplane is greater than 100 knots and until landing gear retraction.
For the reasons described above and pending the development of a permanent solution, this AD requires the deactivation of the electrical powered SOGERMA pilot seats 2510112 series and co-pilot seats 2510113 series.
In addition, this AD provides two (optional) interim solutions in order to restore a partial seat electrical adjustment (vertical only) or a full seat electrical adjustment (vertical and horizontal) by accomplishment of intermediate actions.
Uncommanded movement of the pilot and co-pilot seats during takeoff or landing could interfere with the operation of the airplane and, as a result, could cause consequent loss of control of the airplane.
(f) Actions and Compliance
PDF page 3(f) Unless already done, do the following actions.
(1) Within 15 days after the effective date of this AD: Deactivate the electrical supply of SOGERMA 2510112 series pilot seats and SOGERMA 2510113 series co-pilot seats, in accordance with the instructions of Airbus All Operators Telex (AOT) A310-25A2203, Revision 02, dated March 2, 2009; or AOT A300-25A6215, Revision 02, dated March 2, 2009; as applicable.
(2) For optional intermediate action for restoration of the electrical adjustment of the vertical seat movement only: Deactivating the electrical powered horizontal movement of SOGERMA 2510112 series pilot seats or SOGERMA 2510113 series co-pilot seats, in accordance with the instructions of EADS SOGERMA Alert Service Bulletin A2510112-25-764, Revision 1, dated February 17, 2009, allows restoration of the vertical adjustment only.
(3) For optional intermediate action for restoration of the electrical adjustment of the vertical seat and horizontal seat movement: Inspecting the position of switch ‘S4' and the related shim of SOGERMA 2510112 series pilot seats or SOGERMA 2510113 series co-pilot seats, in accordance with EADS SOGERMA Inspection Service Bulletin 2510112-25-807, dated February 20, 2009, allows reactivation of both horizontal and vertical electrical movements, provided the measurement results of the inspection are within the acceptable value indicated in the service bulletin, and provided that the inspection is repeated thereafter at intervals not to exceed 2 months. If the measurement result of any inspection is not within the acceptable value indicated in the EADS SOGERMA Inspection Service Bulletin 2510112-25-807, dated February 20, 2009, the horizontal movement must be deactivated before further flight.
(4) At the applicable time specified in paragraph (f)(4)(i) or (f)(4)(ii) of this AD: Submit a report of the findings for the first inspection done in accordance with paragraph (f)(3) of this AD to Airbus SAS—EAW (Airworthiness Office), 1 Rond Point Maurice Bellonte, 31707 Blagnac Cedex, France. The report must include a detailed fleet inspection report, including measurement values, and pin and serial numbers for each seat.
(i) If the inspection was done on or after the effective date of this AD: Submit the report within 30 days after the inspection.
(ii) If the inspection was accomplished prior to the effective date of this AD: Submit the report within 30 days after the effective date of this AD.
(5) Modifications made prior to the effective date of this AD in accordance with EADS SOGERMA Alert Service Bulletin A2510112-25-764, dated December 19, 2008, are considered acceptable for compliance with the applicable action specified in this AD.

DiscussionPage 1
The European Aviation Safety Agency, which is the aviation authority for the Technical Agent for the Member States of the European Community, has issued Airworthiness Directive 2009-0084, dated April 9, 2009 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:
An A300-600 operator reported a recent event which occurred during the take-off roll, where a SOGERMA co-pilot seat slid back uncommanded to the end position. The seat horizontal movement actuator was replaced on the affected co-pilot seat. At the following take-off roll the same event occurred, the co-pilot seat sliding back uncommanded again. Further to these events, the inspection carried out on the two removed actuators ARTUS Part Number (P/N) RT19H4FX, revealed that the clutch was broken inside the shaft, thus unlocking the seat horizontal movement.
An unwanted movement of pilot or co-pilot seat in the horizontal direction is considered as potentially unsafe, especially during the take-off phase when the speed of the aeroplane is greater than 100 knots and until landing gear retraction.
For the reasons described above and pending the development of a permanent solution, this AD requires the deactivation of the electrical powered SOGERMA pilot seats 2510112 series and co-pilot seats 2510113 series.
In addition, this AD provides two (optional) interim solutions in order to restore a partial seat electrical adjustment (vertical only) or a full seat electrical adjustment (vertical and horizontal) by accomplishment of intermediate actions.
Uncommanded movement of the pilot and co-pilot seats during takeoff or landing could interfere with the operation of the airplane and, as a result, could cause consequent loss of control of the airplane. You may obtain further information by examining the MCAI in the AD docket.
Relevant service informationPage 2
Airbus has issued All Operators Telex (AOT) A310-25A2203, Revision 02, dated March 2, 2009; and AOT A300-25A6215, Revision 02, dated March 2, 2009. EADS SOGERMA has issued Alert Service Bulletin A2510112-25-764, Revision 1, dated February 17, 2009; and Inspection Service Bulletin 2510112-25-807, dated February 20, 2009. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.
FAA's Determination and Requirements of This ADPage 2
This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.
Differences Between the AD and the MCAI or Service InformationPage 2
We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information.
We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a Note within the AD.
FAA's Determination of the Effective DatePage 2
An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because an uncommanded movement of the pilot and co-pilot seats during takeoff or landing could cause consequent loss of control of the airplane. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days.
Comments invitedPage 2
This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2009-0486; Directorate Identifier 2009-NM-064-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.
Authority for This RulemakingPage 2
Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. “Subtitle VII: Aviation Programs,” describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in “Subtitle VII, Part A, Subpart III, Section 44701: General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.
Regulatory findingsPage 2
We determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify this AD:
1. Is not a “significant regulatory action” under Executive Order 12866;
2. Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket.
Adoption of the amendmentPage 2
Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:
1. The authority citation for part 39 continues to read as follows:
2. The FAA amends § 39.13 by adding the following new AD:
Affected TCDS · 1
The type certificate data sheets for the models this AD names, matched by model and maker.
Registered aircraft · 124
Registered aircraft whose airframe or engine model this AD names. Matched by model only, so check each against the AD’s applicability.
