Accident Details
Probable Cause and Findings
The pilot's loss of directional control during landing. Contributing to the accident was the pilot's failure to attain a proper touchdown point, which required his use of heavy braking to stop on the remaining runway and exacerbated the uneven braking effectiveness of the main wheels.

Analysis
On March 11, 2018, about 1545 Pacific daylight time, an experimental Navajo HKS weight-shift-control aircraft, N1762C, was substantially damaged when it was involved in an accident near Arlington, Washington. The sport pilot sustained minor injuries. The aircraft was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.
The pilot reported that he was landing when, shortly after the aircraft touched down on the main landing gear, he lowered the nose wheel and applied the brakes. The aircraft skidded to the right and came to rest on its right side opposite the direction of landing.
An onboard camera revealed that the aircraft touched down left of the runway centerline about 2,800 ft along the 3,431-ft-long runway; shortly thereafter, it veered to the right and nosed over on the right side of the runway, resulting in substantial damage to the wing and its supporting structure. (see Figure 1.)

The ground steering system comprised a left and right foot peg attached to each side of the nose landing gear strut. Both left and right main landing gear were equipped with hydraulic disc brakes, which operated simultaneously by means of a foot-controlled lever located above the left foot steering peg. The pilot performed an examination of the brakes after the accident and reported that the right wheel brake "had more stopping power" than the left wheel brake. He also stated that his long landing resulted in his application of heavier braking than usual.
