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 that while performing low altitude aerial spray application, he flew too close to a tree instead of flying over the top of it. The left wingtip struck the tree, and the airplane impacted the ground. The wings and fuselage were substantially damaged. The pilot stated that there were no preaccident mechanical failures or malfunctions that would have precluded normal operation.
