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 of the tundra-tire-equipped, tailwheel airplane reported that the airplane landed hard and "bounced pretty good." He applied power to go around, but during the crosswind turn, a downdraft pushed the airplane to the ground. Subsequently, the airplane impacted trees. The airplane sustained substantial damage to the fuselage, empennage, and both wings. After multiple requests, the pilot did not return the National Transportation Safety Board Form 6120.1 Pilot/Operator Aircraft Accident/Incident Report. A review of recorded data from the automated weather observation station located on the airport reported that, about 15 minutes before the accident, the wind was from 170° at 7 knots, gusting to 16 knots. It is unknown which direction the airplane was landing.
