Departure and Initial Contact
The pilot departed Lawton, Oklahoma at 0902 local time on a flight to inspect mineral property. At approximately 0931, the pilot contacted Fort Sill Approach Control and requested vectors to Lawton. The controller instructed the pilot to fly a heading of 320 degrees.
In-Flight Communications
After flying that heading for about six miles, the pilot asked for and was given the Fort Sill weather. Shortly thereafter, the aircraft entered a right turn to a southerly heading. When queried by the controller, the pilot reported he was in VFR conditions and had turned intentionally. Earlier, the radar controller had received reports of a scud layer southeast of Lawton and assumed the pilot was operating VFR on top.
Loss of Radar Contact
The controller provided a heading of 260 degrees and advised that this should take the pilot into a clear area. At 0941, the aircraft disappeared from the radar scope.
Crash Site and Conditions
The plane crashed southeast of Lawton in a wheat field on level terrain. After impact, it traveled about 300 feet before coming to rest. An observer on a rescue helicopter reported the ceiling at the time was 100 to 300 feet with visibility of 1/4 to 1/2 mile.
