Airworthiness Directive · Amendment 39-17372 · Equipment/furnishings
Airbus Airplanes
This AD applies to Airbus Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, F4-605R, F4-622R, and C4-605R Variant F airplanes; and Model A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes; certificated in any category; all manufacturer serial numbers.
We are adopting a new airworthiness directive (AD) for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300- 600 series airplanes); and Model A310 series airplanes. This AD was prompted by a report of an uncommanded slide back of the co-pilot seat to the end stop position. This AD requires a one-time inspection for a part number, a tensile test of the affected seats, and corrective actions if necessary. We are issuing this AD to detect and prevent unwanted movement of a pilot or co-pilot seat in the horizontal direction, which could lead to inadvertent input on the flight control commands and possibly result in loss of controllability 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 6 months after the effective date of this AD, except as provided by paragraph (h) of this AD: Do an inspection to determine the part number of each SOGERMA pilot and co-pilot seat installed on the airplane. As an alternative, a review of the maintenance or delivery records may be used to determine the part number of the pilot and co-pilot seat if the part number can be positively determined from that review.
SOGERMA pilot and co-pilot seats having P/N 2510112 series (all suffixes) or P/N 2510113 series (all suffixes) that, before the effective date of this AD, have already passed the tensile test specified in paragraph (i) of this AD, or have been modified as specified in the Operating Instructions of EADS SOGERMA Inspection Service Bulletin 2510112-25-898, dated April 25, 2012, are not required to be tested, and are considered to be compliant with the requirements of this AD.
If, during the inspection required by paragraph (g) of this AD, the part number of a seat is identified as P/N 2510112 series (all suffixes), or P/N 2510113 series (all suffixes): Within 6 months after the effective date of this AD, do a tensile test on that seat, in accordance with Airbus Alert Operators Transmission (AOT) A25W001-12, dated June 6, 2012.
If the tensile test sample does not break off while performing the test required by paragraph (i) of this AD, before further flight, do one of the actions specified in paragraph (j)(1) or (j)(2) of this AD.
(1) Replace the affected seat with a new or serviceable seat that has passed the tensile test specified in paragraph (i) of this AD. Do the replacement in accordance with Airbus AOT A25W001-12, dated June 6, 2012.
(2) Modify the seat by replacing actuator P/N RT19H4FX of the affected seat, in accordance with the Operating Instructions of EADS SOGERMA Inspection Service Bulletin 2510112-25-898, dated April 25, 2012; or Airbus AOT A25W001-12, dated June 6, 2012.
As of the effective date of this AD, no person may install a SOGERMA pilot or co-pilot seat having P/N 2510112 series, or P/N 2510113 series, on any airplane unless it has passed the tensile test required by paragraph (i) of this AD, or has been replaced or modified as required by paragraph (j) of this AD.
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.
