The flight instructor’s failure to maintain control of the airplane during an encounter with wind while holding short of the runway.
Investigator assessment
Analysis narrative
The flight instructor reported that he was holding short of the runway waiting for a storm with heavy precipitation to pass when a gust of wind lifted the right wing and pushed the airplane to the right side of the runway. The airplane came to rest upside down which resulted in substantial damage to the wing, vertical stabilizer, and rudder. The flight instructor reported he was holding appropriate flight control inputs for the wind at the time the accident occurred. He reported further that there were no mechanical failures or malfunctions with the airplane that would have precluded normal operations.
