Incident Overview
An amateur-built Vans RV-7 was involved in a landing accident on an unimproved turf airstrip. The pilot, during the landing approach, attempted to extend the flaps using the electric flap switch. When no flap movement was observed, the pilot cycled the switch again. The flaps still did not extend, prompting the pilot to decide on a no-flap landing.
Approach and Touchdown
The pilot described making a "low approach to limit glide slope" and maintaining approximately 90 knots indicated airspeed (KIAS). The aircraft touched down within the first third of the runway, with the main landing gear contacting the ground first. Subsequently, the pilot pulled the control stick aft, allowing the tailwheel to make contact with the ground, and applied full brakes in an effort to slow the airplane.
Post-Touchdown Sequence
Upon braking, the airplane began sliding on the damp grass surface. The slide continued until the aircraft impacted trees located at the end of the runway. The impact resulted in substantial damage to the left wing.
Examination Findings
A Federal Aviation Administration (FAA) inspector examined the airplane following the accident. The inspection did not reveal any evidence of preimpact failures or malfunctions with the aircraft. No specific cause for the flap malfunction was identified in the source.
