Location: Hayward, Wisconsin 
Accident Number: CEN21LA280
Date and Time: June 18, 2021, 12:20 Local 
Registration: N729SA
Aircraft Damage: Substantial
Defining Event: Loss of control on ground 
Injuries: 1 None
Flight Conducted Under: Part 91: General aviation - Personal


The pilot completed a short cross-country flight and checked the wind conditions at the destination airport. He reported the automated weather station was out of service but received weather and runway information from an air traffic controller and airport personnel. The on-board weather information reported the wind was 10 to 12 kts at a 60°crosswind angle, so he set up for a normal landing. The pilot added that when he was about 30 to 50 ft agl, the airplane was hit with a gust of wind. He pulled back on the controls and stalled the airplane. The airplane bounced onto the runway, so the pilot elected to do a go-around. He applied throttle; however, the airplane veered left and impacted a drainage ditch. During the accident, the nose landing gear collapsed, and the right wing sustained substantial damage. About the time of the accident, the automated weather reporting station located 23 miles northwest of the accident site reported, wind from 290° at 10 kts gusting to 21 kts.

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 during landing with gusting wind.

  1. Brand new... capable bird able to get you from A to B as good as the airlines and messed up by a low time private with too much money and not enough skills. Hard truth.

    1. And you wonder why GA insurance is so expensive.

    2. And a million dollar bird at that which is notorious for biting green pilots fresh off a Skyhawk or Cherokee flown private ticket thinking they can handle it. High takeoff and landing speeds and being unforgiving in pattern slow flight is not for the beginner pilot.

  2. PPPPPP....
    prior planning prevents pis poor performance...
