Accident Sequence
The aircraft was conducting a visual flight rules (VFR) final approach at an altitude of 100 feet above ground level (AGL) when it rolled over. It then entered an uncontrolled descent and struck the roof of a warehouse. The impact broke a skylight in the roof, and the aircraft fell through the resulting hole, coming to rest inside the warehouse.
Observed Debris in Cabin
Following the accident, an examination of the aircraft cabin revealed the presence of rocks, hand tools, and a large unsecured tree stump. The tree stump exhibited a fresh scar and black paint smears in the area adjacent to the cyclic control stick. The cyclic control stick was black in color. A screw head on the cyclic control stick was found to be filled with wood splinters.
Final Position
After breaking through the skylight, the aircraft came to rest on the interior floor of the warehouse. The roof damage consisted of the broken skylight through which the aircraft had fallen.
