Probable cause

The pilot's excessive braking during landing roll. Contributing factors to this accident were the pilot's lack of experience in the accident airplane.

Analysis

The experimental airplane nosed over during landing roll after a brake application to correct from a drift. When the airplane began to drift to the right, the pilot applied left brake. The airplane then started to rotate to the left, and the pilot applied right brake. The airplane then nosed over. The airplane's brakes and rudder pedals were collocated with each other instead of having a toe brake configuration. The pilot had a total time of 4 hours in the make and model of the accident airplane.

Factual narrative

On June 13, 2003, at 1238 central daylight time, an experimental New Standard D-25, N930V, operated by the EAA Aviation Foundation Inc. (EAA), sustained substantial damage when it nosed over while landing on runway 31 (4,494 feet by 75 feet, asphalt) at West Bend Municipal Airport, West Bend, Wisconsin. Visual meteorological conditions prevailed at the time of the accident. The commercial pilot and passenger reported no injuries. The 14 CFR Part 91 personal flight was not operating on a flight plan. The flight departed Wittman Regional Airport, Oshkosh, Wisconsin, about 1200.

The pilot reported the airplane drifted to the right of the runway centerline while landing. The pilot indicated he increased rudder to compensate for the drift. The pilot noted he applied left brake to keep the airplane on the runway centerline. The pilot stated the airplane started to rotate to the left so he subsequently applied right brake. The airplane then nosed over.

The pilot reported the brake pedal configuration of the airplane was unusual to him. The pilot stated that the brake and rudder pedals were located next to each other instead of the usual toe brake configuration. The pilot stated that because of the unusually large upper wing and its separate brake and rudder peddles, a low crosswind limit of 10 mph had been designated.

The pilot reported a total flight time of 4 hours in the accident airplane make and model, of which 4 hours were in the past 90 days and 3 hours were in the past 30 days.

The winds at the accident site were recorded at 1237 as light and variable.
