Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported he was landing on runway 36 when the accident occurred. He listened to the automated weather reporting station from an airport 13 miles away and the wind was reported as being from 350 degrees at 5 knots. He stated he established a crab angle to compensate for the wind while on final approach. Upon reaching an altitude of 50 feet above the ground, he noticed a decrease in the crosswind and an increased sink rate. The airplane traveled to the left side of the airstrip where it contacted high brush. The airplane yawed further to the left where it contacted trees resulting in substantial damage to the wings and fuselage.
