Aircraft Damage: Substantial
Defining Event: Hard landing

Analysis
According to the pilot, he departed in a single-seat homebuilt airplane; however, the airplane did not feel "stable", so he elected to abort the takeoff. During touchdown, the airplane's nose landing gear hit the runway first. After the nose landing gear struck the runway, the rudder was jammed, and the airplane departed the runway surface. The airplane struck a runway light before coming to a stop. Examination of the airplane found that firewall damage had impacted and jammed the nosewheel steering and rudder controls. Damage to the airplane's left-wing leading edge, and substantial damage to the left horizontal stabilizer, and elevator were also noted.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's hard landing on the airplane's nosewheel, which jammed the steering, and resulted in a runway excursion and impact with runway lights.
Findings
