Injuries: 1 Serious.

NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

The pilot was dispatched on a nonscheduled cargo flight to an airport other than his usual destination because it had a precision instrument approach, while his usual destination airport did not. The pilot elected to fly to his usual airport, and attempted a nonprecision instrument approach. The airport had both a VOR and an NDB approach. The NDB approach was noted as being out of service, although there was still a radio signal coming from the navigation aid. The pilot was cleared for the VOR approach, although instrumentation inside the cockpit was found set for the NDB approach, and radar track data disclosed that the flight path was consistent with the NDB approach path, not the VOR's. The airport's reported weather was 1.25 miles visibility, with a 200-foot overcast in mist. The airport's minimum NDB approach altitude is 652 feet above touchdown height. The airplane did not reach the runway, and collided with a pole and a building. Inspection of the airplane disclosed no evidence of any preimpact mechanical malfunctions.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's descent below minimum descent altitude while on a nonprecision approach. A contributing factor was a low ceiling.
