Aviation Accident Final Report - National Transportation Safety Board

Investigation Docket - National Transportation Safety Board:

Location: Gulkana, Alaska
Accident Number: ANC20CA054
Date & Time: May 23, 2020, 19:00 Local
Registration: N72536
Aircraft: Cessna 120 
Aircraft Damage: Substantial
Defining Event: Collision during takeoff/land
Injuries: 1 None
Flight Conducted Under: Part 91: General aviation - Personal


The pilot reported that while landing at an unimproved airstrip, his airspeed on final approach was too fast, and he decided to perform a go-around. During the go-around, the left main tire struck trees at the departure end of the airstrip and the airplane subsequently descended into the brush and trees. The right wing and right elevator sustained substantial damage. The pilot stated there were no preaccident mechanical malfunctions or anomalies that would have precluded normal operation.

In the recommendation section of the NTSB Accident/Incident Reporting Form 6120.1, the pilot stated that the accident may have been prevented if he had been more aware of his limitations and the airplane's performance limitations.

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 proper airspeed during final approach to landing, and his subsequent failure to attain sufficient altitude to clear trees during an attempted go-around.
