Additional Participating Entity:

Investigation Docket - National Transportation Safety Board:

Location: Pell City, Alabama
Accident Number: ERA20CA293
Date & Time: August 6, 2020, 10:22 Local
Registration: N30492
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 1 Minor, 1 None
Flight Conducted Under: Part 91: General aviation - Instructional


The flight instructor was providing initial flight training to the non-certificated student pilot in a tailwheel-equipped airplane. The flight instructor reported that while the student pilot was landing the airplane it began veering left immediately after touchdown. The flight instructor attempted to correct the yaw and applied the brakes, but the airplane continued off the left side of the runway with the tailwheel still in the air. The airplane impacted some dirt, which resulted in a nose over and substantial damage to the airplane’s left wing, empennage, vertical stabilizer, and rudder. The flight instructor reported that there were no mechanical malfunctions or failures of the airplane that would have precluded normal operation. Additionally, the flight instructor reported that the student pilot had accumulated about 2 hours of flight experience at the time of the accident and described that she, “…was showing great aptitude with landings but I should have delayed her attempting to do so to further in her training.”

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The flight instructor’s inadequate remedial action following the student pilot’s loss of directional control during landing, which resulted in a runway excursion and subsequent nose over.
