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 stated that he was departing east from a 900-foot-long by 50-foot-wide private turf runway. When the airplane was about 20 feet above the ground, a "significant" wind gust pushed the airplane left, and its left wing contacted a tree branch and spun the airplane around. The airplane incurred damage to both wings and the engine separated from the airframe. Reported winds in the vicinity, about the time of the accident, were from the west at 13 knots. When asked how the accident could have been prevented, the pilot stated that he should have remained south of the runway centerline as the predominant winds are southerly. Examination of the wreckage by a Federal Aviation Administration inspector did not reveal any preimpact mechanical malfunctions, nor did the pilot report any.

Factual narrative

The pilot stated that he was departing east from a 900-foot-long by 50-foot-wide private turf runway. When the airplane was about 20 feet above the ground, a "significant" wind gust pushed the airplane left, and its left wing contacted a tree branch and spun the airplane around. The airplane came to rest facing opposite the direction of the departure, and had incurred damage to both wings, in addition to separating the engine from the airframe. Reported winds in the vicinity, about the time of the accident, were from the west at 13 knots. When asked how the accident could have been prevented, the pilot stated that he should remain south of the runway centerline as the predominant winds are southerly. Examination of the wreckage by a Federal Aviation Administration inspector did not reveal any preimpact mechanical malfunctions, nor did the pilot report any.
