### TITLE: EQUIPMENT/FURNISHINGS - FLIGHT COMPARTMENT SEATS - INSTALL ENLARGED SHIM FOR HORIZONTAL SWITCH ACTUATION **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR 13500S22802 MINOR None NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics affecting the airworthiness of the product. All other changes are major changes. REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES Powered captain and first officer seats are equipped with an actuator for the horizontal displacement limited by an end switch, which detects the end seat displacement and stops the actuator thanks to a cam detecting device. An A300-600 aircraft operator reported that during take-off roll, the first officer seat PN 2510113-05-14, manufactured by SOGERMA, slid back by itself to the end stop position. Command was transferred to the captain and flight continued uneventful. As wide body model families can be installed with SOGERMA seats PN 2510113 and 2510112 series, the above conditions might also exist on the model family addressed in the Service Bulletin. This Service Bulletin is published to advise all operators of A310/A300-600 (or A300-600 ST) aircraft of the issue of SOGERMA-SOCEA Service Bulletin No. 2510112-25-813. This Service Bulletin requires to change the cam by a new larger one and the switch S4 bracket. The reason of the seat slippage is due to the misalignment of an electrical stop switch that causes the actuator failure. The reason of this misalignment is due to a bad adjustment of the seat pan.
