Investigation Docket - National Transportation Safety Board:

B407 LLC

Location: Talkeetna, Alaska 
Accident Number: ANC21LA055
Date and Time: July 3, 2021, 23:00 Local 
Registration: N82547
Aircraft: Piper PA-18-150
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 1 None
Flight Conducted Under: Part 91: General aviation - Personal


The pilot of the tailwheel-equipped airplane reported that during takeoff he pushed forward aggressively on the control stick which resulted in a nose-down pitching moment exacerbated by fuel sloshing forward in the wing fuel tanks. In an effort to correct for the pitching moment, he pulled aft on the control stick which caused the tailwheel to impact the ground and the airplane veered to the left. Unable to correct for the veer, he applied the brakes too hard which resulted in a nose-over. The airplane sustained substantial damage to the right lift strut and vertical stabilizer. The pilot reported that there were no preaccident mechanical malfunctions or anomalies with the airplane that would have precluded normal operation, and that the accident may have been prevented if he had been less aggressive when applying flight control inputs.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot’s improper flight control inputs which resulted in a loss of directional control and a nose-over.
