Pasco - Spokane

The pilot received abbreviated weather briefing for emergency medical service (EMS)/air ambulance flight. Before flight, he expressed anxiety about possible low visibility for landing and timely transport of dying patient. During ILS runway 03 approach (rwy 03 approach), the aircraft remained well above the glide slope until close to the middle marker; aircraft's speed decreased from 153 to 100 kts, while vertical speed increased from 711 feet/min to about 1,250 feet/min descent. About 1 mile from runway and 500 feet agl (in fog), the aircraft abruptly turned left of localizer course and gradually descended with no distress call from pilot. The aircraft hit a pole, then flew into a building and burned. Low ceiling, fog and dark night conditions prevailed. Pilot (recent ex military helicopter pilot) had logged/reported 3,500 hours of flight time and about 150 hours in multiengine airplanes, but there was evidence he lacked experience with actual instrument approaches in fixed wing aircraft; he had difficulty with instrument flying during recent training and FAA check flights. No preimpact mechanical problem was found with aircraft/engines. No ILS anomalies were found. Flight nurse was using cellular phone, but no evidence was found of interference with aircraft's navigational system. Visibility and ceiling at destination were less than forecast at time of pilot's preflight weather briefing. Paramedic was only survivor.
