Probable Cause Approval Date: 09/07/2017
Aircraft: CESSNA 170B, registration: N3442D

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot said that he was departing in his airplane from the downhill-sloping (east) runway at 9AK with a slight tailwind. He said that, as the airplane tried to become airborne, the tailwind increased considerably, and the airplane would not climb. The airplane struck brush that encroached the east end of the runway area and veered left into brush and small trees. He stated that no mechanical failures or malfunctions of the airplane precluded normal operation. Damage included the separation of the right outboard elevator. Photographs of the airstrip provided by the pilot showed that 9AK was a short, narrow, rough-surfaced airstrip with brush growth encroachment.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The airplane's encounter with a tailwind during takeoff from a short, narrow airstrip, which resulted in a loss of lift and collision with brush and small trees.
