Analysis

The pilot said that while he was taxiing out for takeoff on runway 22, he was monitoring the airport's Automatic Weather Observation Station (AWOS), and winds were reported to be gusting 34 to 36 knots. While turning from northwest to northeast on the taxiways, the airplane's left wing lifted up and the airplane nosed down. The AWOS wind report approximately 3 minutes after the accident was 250 degrees at 27 knots, gusting to 43 knots. The manufacturer's Information Manual for this airplane states that the maximum demonstrated crosswind velocity is 20 knots (not a limitation).
