Narrative:Citation N22HP departed Greater Rockford Airport (RFD) at 08:43 CDT on a flight to Dillon, MT (DLN). At 09:52 MDT, the pilot indicated that he was level at FL380. At 10:10:30, he stated that he was beginning a descent to FL240. At 10:30:59, a controller cleared the pilot to descend to 13,000 feet, and then cleared him for the VOR approach to the Dillon Airport. The last transmission from the pilot occurred at 10:33:54. He acknowledged cancellation of radar service and an instruction to switch to the airport advisory frequency.
At that time, the airplane was at a mode C reported altitude of 14,000 feet. The airplane maintained a steady descent rate for the next minute and leveled off at 13,000 feet. About 2 1/2 minutes later, the airplane began a turn to the right to head outbound for the procedure turn on the approach and descended to 12,900 feet. The approach procedure specified a minimum altitude of 8,200 feet in the procedure turn. The airplane lost 1,600 feet in the next 10 seconds, and this was the last radar contact. A witness saw an airplane below the cloud bases that was turning to the right with a nose low pitch attitude of about 75 to 80 degrees. It made six to seven turns before it disappeared from sight behind terrain, and the radius of the turn got tighter as the airplane descended.
PROBABLE CAUSE: "An in-flight loss of control for undetermined reasons."
