History of the Flight
The pilot, holding a Private Pilot's Licence with 216 total flying hours (15 on type), completed a full pre-flight check and performed a successful full-stop circuit. For the second circuit, during the downwind leg, he selected the first stage of flap. On final approach, he selected full flap. The approach, flare, and initial touchdown were normal, but shortly after touchdown, the aircraft became airborne again due to the undulating and bumpy airstrip. The pilot initiated a go-around, applied full power, and selected the first stage of flap. The aircraft did not climb, and the stall warning sounded. Shortly thereafter, the right wing dropped, and the aircraft struck the ground with the right main landing gear wheel, followed by the nosewheel. After coming to rest, the pilot switched off all systems and exited through the pilot's door. No injuries were sustained.
Damage
The accident caused damage to both wings, the right main landing gear, the nosewheel, the propeller, the engine mountings, and the windscreen.
Probable Cause
The pilot assessed that the probable cause of the accident was that he inadvertently retracted all of the flap, instead of retracting it to the first stage, and this allowed the aircraft to enter a stall.
