Contributing factors to the accident were the gusting wind conditions and the trees. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, approach - vfr pattern - final approach - weather condition - gusts (contributing factor) - compensation for wind conditions - inadequate, pilot in command (cause) - In flight collision with object, descent - uncontrolled - object - tree(s) (contributing factor) - In flight collision with terrain/water, descent - uncontrolled - terrain condition - ground ## Analysis The airplane impacted trees and terrain while on final approach. The pilot stated that he was landing on a private grass airstrip toward the north. The pilot described the weather as a "clear day, but with high winds." The pilot reported that while on final approach he encountered "wind shear straight down." The pilot stated that the airplane "clipped the tree tops" before impacting terrain. The pilot reported the airplane came to rest along a tree line near the west edge of the north-south runway. The pilot stated that the accident could have been prevented if he had not attempted flight in the high/gusting wind conditions or by entering final approach at a higher altitude. The wind conditions at an airport approximately 15 nautical miles from the accident site were reported to be from 200 magnetic degrees at 9 knots, gusting to 16 knots. The pilot's medical and student pilot certificate had expired 20 months prior to the accident. The pilot's most recent 90-day solo endorsement was dated September 17, 2003. ## Factual narrative The airplane impacted trees and terrain while on final approach.
