Location: Nenana, Alaska
Accident Number: ANC21LA046
Date and Time: June 13, 2021, 08:30 Local
Registration: N178TT
Aircraft: Bellanca 8GCBC 
Aircraft Damage: Substantial
Defining Event: Collision with terr/obj (non-CFIT) 
Injuries: 1 None
Flight Conducted Under: Part 91: General aviation - Personal


After takeoff the private pilot flew to several different airstrips where he performed several full-stop landings. He then elected to fly to the “Lynx Strip” and flew across the runway and did not notice any “significant [wind]” at low altitude or on the water of a nearby pond. He performed two passes over the runway from different directions and again noted the wind was “negligible.” He performed two landings to the north then a full stop landing to the south. He departed and performed a “left traffic teardrop” for a final landing to the north. Either at touchdown or just moments before he felt drag on the right wing and realized the right wingtip was, “in the small Black Spruce [trees] to the right of the runway.” He applied left rudder and some aileron input to correct back to center, but the drag on the right wing increased. The airplane made an arc to the right and contact black spruce trees off the right side of the runway coming to rest upright perpendicular to the runway facing east.

According to the airplane manufacturer, the total wingspan of the airplane was about 36 ft. Postaccident examination of the airplane revealed damage to the leading edges of both wings which was greater than 10% of the total wingspan; therefore, the damage was considered substantial.

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 adequate clearance with trees during landing.
