Flight and Pilot Information
An instrument-rated pilot with 3,864 hours of flight experience was en route to his intended destination. He was familiar with the route, having completed approximately 370 flights between the departure and destination airports.
ATC Communication
While en route, the pilot requested a GPS instrument approach to the intended destination airport from air traffic control. ATC denied the request due to traffic and low cloud bases in the area. The pilot then requested an IFR clearance to an alternate airport. ATC cleared the pilot for an ILS approach to the alternate airport. Subsequently, the pilot reported that when able, he would cancel the IFR clearance and proceed to the intended destination airport under VFR.
Witness Observations
Witnesses observed the airplane flying northbound towards the intended destination airport. They described it as operating "low, fast and its landing gear was up." The weather at the time was reported as "very rainy, and foggy and the visibility was poor." The airplane continued north and disappeared instantly into the fog and clouds. No distress calls were received from the pilot prior to the accident.
Accident and Wreckage
The airplane impacted trees and terrain at an elevation of approximately 5,675 feet msl. During examination of the wreckage, no aircraft or engine anomalies were noted that would have prevented normal operations.
