Private Airstrip Airport
Aircraft Accident/Incident Report

Barton City, Michigan 48705
Thursday, September 20, 2007 16:00 EDT

NTSB Narrative Summary Released at Completion of Accident

The airplane departed to the northwest from a private grass airstrip situated behind the pilot's residence. The passenger reported that shortly after takeoff the airplane encountered a large wind gust that pushed the airplane to the left (southwest). After encountering a second wind gust, the airplane banked sharply and then descended vertically into trees and terrain. The passenger recalled that the airstrip's windsock did not indicate that there was significant wind prior to the accident flight. The pilot had no recollection of the accident flight. A weather observation station located about 16 nm south-southeast of the accident site reported the wind was from the east at 5 knots with no gusts. Another weather observation station located about 23 nm west of the accident site reported the wind was from the west-southwest at 4 knots, gusting to 10 knots.

NTSB Probable Cause Narrative

The pilot's failure to maintain adequate airspeed and aircraft control during initial climb after takeoff. Contributing to the accident was the gusting wind condition.
