This assembly is a Chassis Connector Assembly from a Slat & Flap Electronic Control Unit (SECU). It holds the main LRU connectors, the Motherboard and some circuitry and the given size is with the two flexi-circuits extended flat.
Also referred to as high lift or secondary flight controls, Slat & Flap Electronic Control Units (SFECUs) enable optimum take-off and landing speeds by increasing wing lift.
The SFECU is installed in the equipment bays in the body of the aircraft and it controls the Slats and Flaps (on the wings) utilized during take-offs and landings. When the Slats and Flaps are extended, they make the area of the wing bigger; they increase lift which enables the pilot to control the speed and enables the aircraft to fly more slowly.
