At approximately 1000 Pacific time, the pilot of a Cessna 185 lost control during the landing roll at Deer Park Airport. Neither the pilot nor the flight instructor was injured. The pilot told investigators he had not flown a conventional gear aircraft in several years and wanted to be checked out by a qualified instructor. Prior to the accident flight he had received approximately 4 hours of dual instruction in the aircraft but did not yet feel comfortable in the airplane. The pilot made a wheel landing and the airplane veered, but the pilot just lost it, he reported. The aircraft struck a berm and a snow drift off the right side of the runway before flipping over and coming to rest inverted. The pilot said he did not think the instructor provided any assistance in helping him recover from the loss of control.
