Accident Sequence
A pilot was cleared for a night NDB runway 19 approach to Folwom Field. Witnesses reported a 200-foot ceiling and reduced visibility due to fog at the airport. Radar tracking showed erratic movements during the procedure turn and inbound intercept. Other witnesses observed the aircraft on a northbound course, followed by a turn to the west at rooftop height, well below the minimum descent altitude (MDA), at a point one mile northeast of the airport. The engine sounded normal. The aircraft contacted trees at about airport elevation, one mile north of the airport. The wreckage path measured 632 feet. Examination of severed limbs, propeller damage, and the engine revealed evidence of power at impact.
