NTSB Identification: WPR11CA022
14 CFR Part 91: General Aviation
Accident occurred Thursday, October 21, 2010 in Colville, WA
Probable Cause Approval Date: 03/16/2011
Aircraft: Rotherwick Glasair III, registration: N471B
Injuries: 2 Minor.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot reported that he was landing the airplane in calm wind conditions. The airplane touched down midway down the runway at stall speed. Upon touchdown, the pilot retracted the flaps and applied brake pressure, including full aft elevator, in an attempt to bring the airplane to a stop. With the end of the runway approaching, the pilot applied left brake in an effort to turn the airplane to the left and the airplane nosed over off the end of the runway. The pilot stated that he checked the brakes prior to flight, but felt that they did not function normally during the landing. A witness reported that when the airplane was landing, it floated in ground effect until about 100 feet beyond midfield. The landing gear contacted the runway and the airplane continued to decelerate until disappearing over the end of the runway. According to a Federal Aviation Administration (FAA) inspector that responded to the accident, skid marks led from the runway to the location where the airplane came to rest. The FAA inspector examined the braking system following the accident and found no mechanical anomalies. At the time of this writing, the pilot had not submitted NTSB Form 6120.1, the Pilot/Operator Aircraft Accident/Incident Report.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's misjudged approach and failure to attain the proper touchdown point, which resulted in a runway overrun.
