He noted no extension of the flaps and re-cycled the switch. The flaps did not extend and the pilot decided to conduct a no-flap landing. The pilot stated that he made a "low approach to limit glide slope and maintained about 90 kias [knots indicated airspeed]." The airplane touched down in the first 1/3 of the runway, with the main landing gear contacting the ground first. The pilot pulled the control stick aft, allowing the tailwheel to contact the ground, and applied full brakes to slow the airplane. The airplane began sliding on the damp grass and impacted trees at the end of the runway, substantially damaging the left wing. Examination of the airplane by a Federal Aviation Administration inspector did not reveal evidence of any preimpact failures or malfunctions with the airplane. ## Factual narrative While landing on an unimproved turf airstrip, the pilot of the amateur-built Vans RV-7 attempted to lower the flaps using the electric flap switch.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
