Accident Number:GAA19CA359
Date & Time: 06/18/2019, 2020 MDT
Registration: N882M
Aircraft: AUTOGYRO GMBH Cavalon
Aircraft Damage: Substantial
Defining Event: Loss of control in flight
Injuries: 1 Minor
Flight Conducted Under: Part 91: General Aviation - Flight Test


The pilot reported that, during takeoff, he rotated around 55 knots and that the gyroplane instantly yawed left about 45°. The pilot reported that he was "behind the power curve" and that the gyroplane could not climb or gain airspeed. The gyroplane began to descend, the pilot turned left, and the gyroplane landed hard and rolled to the right side.

The pilot added that he believed that the gyroplane initially yawed left during the climb because of the "P-factor due to [a newly installed] more powerful engine" and that he failed to add right rudder input to correct. He added that it was his first test flight with the new engine.

The gyroplane sustained substantial damage to the tailboom.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the gyroplane 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 insufficient rudder input during takeoff, which resulted in a loss of yaw control and a hard landing. 


Rudder control system - Not used/operated (Cause)
Yaw control - Not attained/maintained (Cause)

Personnel issues
Aircraft control - Pilot (Cause)
Total experience w/ equipment - Pilot

NEPHI, Utah, June 19, 2019 (Gephardt Daily) — A Davis County man was transported to the hospital Tuesday evening after a gyrocopter crash at the Nephi Municipal Airport.

Brent Pulver, chief deputy of the Nephi City Police Department, told Gephardt Daily that the call came to dispatch at about 8:45 p.m.

“It was a small gyrocopter,” Pulver said. “The pilot said he was out practicing touch-and-go, and was 60 to 80 feet in the air when he lost power. He had issues with the gyrocopter, and he landed hard. The gyrocopter went onto its side.

Pulver said the man “is doing OK.”

“He was out there alone, and was able to get out and walk to the hanger. He ended up finding someone to give him a ride to the hospital. His injuries were non life-threatening.”

The man in the single person crash was a 66-year-old Kaysville resident, Pulver said. His name has not been released.

Pulver said the gyrocopter, a single-person craft, was still in place as of 1 p.m. Wednesday, awaiting a crash investigation by officials from the Federal Aviation Administration and the National Transportation Safety Board.
