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 and passenger had just completed a local flight from a private airfield. The pilot reported that he flared for the landing with the airplane’s airspeed between 60 and 65 mph at 3 to 4 feet above the ground, and the left wing dropped abruptly. The airplane’s left landing gear hit the ground hard and the airplane bounced; the pilot was then able to recover for a normal 3-point landing. An examination of the airplane revealed substantial damage to the fuselage. The pilot stated that it felt as though the airplane was pushed to the ground, which he believed was due to a strong downdraft or gust of wind. Wind in the area about 40 minutes before the accident was reported to be from 170 degrees at 7 knots.
