Airbus A300B4-605R, G-MAJS
The co-pilot inadvertently retracted the slats and flaps after takeoff instead of raising the landing gear. The aircraft continued to climb but the stall warning system operated twice before the aircraft accelerated to the normal climb speed. A slat technical issue after engine start had required the co-pilot to operate the slats/flap lever several times to clear the fault. These actions, coupled with a mental rehearsal of the procedure that the pilots would need to action should the fault recur on takeoff, had mentally predisposed the co-pilot to operate the slats and flaps lever after takeoff despite his intention to operate the landing gear lever.
