Aviation Accident Final Report - National Transportation Safety Board

Additional Participating Entity: 
Federal Aviation Administration / Flight Standards District Office; Des Moines, Iowa

Investigation Docket - National Transportation Safety Board: 

Location: Pisgah, Iowa 
Accident Number: CEN20CA244
Date & Time: June 23, 2020, 14:19 Local
Registration: N7764W
Aircraft: COYOTE S-6ES
Aircraft Damage: Substantial
Defining Event: Aerodynamic stall/spin
Injuries: 1 Serious
Flight Conducted Under: Part 91: General aviation - Personal


The uncertificated pilot reported he had been studying an on-line course with the intent of pursuing a sport pilot certificate in the future. He purchased the airplane about a month prior to the accident, and the accident flight was his first flight in the airplane. He stated he was aware of a cross wind coming from his right at his airstrip, and the ground dropping away into the adjacent bean field at the end. He planned to get airborne and then as the ground dropped away into the field, he would turn right into the wind and climb. He said that the airplane climbed faster than anticipated, and the wind turned the airplane toward the left. He stated that he did not remember much after that, other than some of the postcrash events in the field. The pilot stated he had seen a video the accident, and it appeared the left wing stalled, and the airplane spun into the field. The airplane sustained substantial damage that included damage to both wings and the fuselage. The pilot stated there was no mechanical anomalies that would have precluded normal airplane operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The uncertificated pilot's failure to attain/maintain a proper angle-of-attack during an initial climb that resulted in an aerodynamic stall and subsequent impact with terrain.

  1. Now, folks, we've seen it all: an unlicensed pilot who learned how to fly online crashed his airplane on the VERY. FIRST. FLIGHT.

    I'd say that's a testament to the system working. You're not supposed to be able to fly an airplane without the proper training. Sadly this guy's judgment was the only thing worse than his flying skills.
