Analysis

The pilot reported that the takeoff roll and liftoff were normal, however, shortly after becoming airborne he experienced a lower than normal rate of climb. As the airplane approached the end of the field, the pilot turned to the west toward lower terrain in an effort to clear the approaching tree line. The pilot stated that after initiating the turn, the airplane collided with trees and ultimately impacted terrain in an inverted, nose-low attitude. The departure airstrip is approximately 2,000 feet in length and is bordered by large trees. The field elevation is approximately 2,800 feet MSL. No mechanical malfunctions or failures were reported.

Factual narrative

On June 8, 2004, about 0900 mountain daylight time, a Piper PA-18A, N7094D, was destroyed after colliding with trees and terrain shortly after takeoff from an alfalfa field/airstrip near Trego, Montana. The airplane was being operated as a visual flight rules (VFR) positioning flight under the provisions of 14, CFR Part 91, when the accident occurred. The certificated commercial pilot, the sole occupant of the airplane, sustained minor injuries in the accident. The airplane is owned by Kasilof Fisheries, Inc, of Trego, Montana. Visual meteorological conditions prevailed and no flight plan was filed for the flight. The pilot's planned destination was Eureka, Montana.

In a telephone conversation with the National Transportation Safety Board IIC on June 14, the pilot reported that the takeoff roll and liftoff were normal, however, shortly after becoming airborne he experienced a lower than normal rate of climb. As the airplane approached the end of the field, the pilot turned to the west toward lower terrain in an effort to clear the approaching tree line. The pilot stated that after initiating the turn, the airplane collided with trees and ultimately impacted terrain in an inverted, nose-low attitude.

The departure airstrip is approximately 2,000 feet in length and is bordered by large trees. The field elevation is approximately 2,800 feet MSL.

No mechanical malfunctions or failures were reported.
