A pilot attempted an off-airport takeoff in variable winds. A tailwind extended the roll, preventing adequate climb-out. The aircraft struck a creek, causing substantial damage to the fuselage and vertical stabilizer.

Incident Overview

The accident involved a general aviation aircraft operating from an unimproved site rather than a certified airport. The pilot initiated the takeoff procedure under conditions characterized by variable wind speeds and directions.

Operational Sequence

During the initial ground roll, the aircraft encountered a tailwind component. This aerodynamic condition reduced the effective airspeed relative to the ground, resulting in a significantly extended takeoff distance. Consequently, the airplane failed to achieve the necessary rate of climb to clear the surrounding topography.

Impact and Damage

Unable to outclimb the terrain, the aircraft descended into a creek bed. The impact caused the nose of the airplane to pitch over sharply. Post-accident inspection revealed substantial structural damage concentrated in the fuselage and the vertical stabilizer.
