Investigation Docket - National Transportation Safety Board:


Location: Minneapolis, Minnesota 
Accident Number: CEN20CA251
Date & Time: June 25, 2020, 11:45 Local
Registration: N951X
Aircraft: SONEX ONEX
Aircraft Damage: Substantial
Defining Event: Hard landing
Injuries: 1 None
Flight Conducted Under: Part 91: General aviation - Personal

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

Personnel issues Aircraft control - Pilot
Aircraft Landing flare - Incorrect use/operation

Flight Conducted Under: Part 91: General aviation - Personal

Analysis

The pilot of the helicopter was flying over mountainous terrain, about 500 ft agl, with moderate wind and turbulence conditions. After he slowed the helicopter to 60-70 knots it suddenly and uncontrollably descended at a rapid rate in a severe downdraft. The pilot maneuvered toward lower terrain to accelerate but was unable to arrest the descent before the helicopter collided with the ground tail first. The helicopter fuselage was substantially damaged. The pilot reported that there were no preaccident malfunctions or failures with the helicopter that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain directional control of the airplane during an aborted landing, which resulted in a ground loop, runway excursion, and subsequent nose over.

Findings

Personnel issues Aircraft control - Pilot
Aircraft Altitude - Not attained/maintained
Environmental issues Downdraft - Effect on operation
