Accident Number: WPR22LA135
Date and Time: March 23, 2022, 10:45 Local
Registration: N863SL
Aircraft: AIRPLANE FACTORY (PTY) LTD SLING LSA
Aircraft Damage: Substantial
Defining Event: Loss of control in flight
Injuries: 2 None
Flight Conducted Under: Part 91: General aviation - Instructional

Analysis

The flight instructor of the airplane reported that, during an instructional flight with a student flight instructor, he purposely “flared too much and a little too high.” The intent was for the student flight instructor to correct; however, he did not intervene. The flight instructor added full power to abort the landing when the airplane encountered a shift from a headwind to a right quartering tailwind and the airplane drifted to the right. While maneuvering the airplane to stay over the runway, the left aileron struck a runway sign. The airplane sustained substantial damage to the left aileron. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane 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 flight instructor’s loss of airplane control during an aborted landing due to a wind shift, which resulted in an impact with a runway sign.

Findings

Aircraft Directional control - Not attained/maintained
Personnel issues Aircraft control - Instructor/check pilot
Environmental issues Sudden wind shift - Effect on operation
Environmental issues Sign/marker - Effect on equipment
