On June 21, 1996, at 1945 Pacific daylight time, a Cessna 182A, N9975B, registered to and operated by Verticle Ventures Inc. as a 14 CFR Part 91 business flight, collided with a ditch during a forced landing after the engine experienced a loss of power during a go-around at the Toledo Airport, Toledo, Washington. Visual meteorological conditions prevailed at the time and no flight plan was filed. The airplane was substantially damaged and the commercial pilot, the sole occupant, was not injured. The pilot reported that he had just dropped parachutists from 13,000 feet and was returning to the airport. The pilot stated that while on final approach to runway 23, he did not like how the airplane was set up for the landing and opted to go-around. During the go-around, the engine lost power. The pilot stated that he forced landed the airplane near the end of the runway. During the landing roll, a main landing gear collapsed and the airplane slid sideways into a ditch. The pilot further stated that radio controlled model aircraft were flying near the approach end of the runway. The model airplanes were supposed to use only 1,000 feet of the approach end of the runway, however, the pilot stated that while he was on the base leg, two of the model airplanes swung wide and blocked the first 2,000 feet of the runway, thus moving the pilot closer to the departure end of the runway. The pilot's diagram of the events indicates that he was approximately 2/3 of the way down the runway when the go-around was started and 500 feet from the end of the runway when the engine lost power. Initial inspection of the airplane determined that there was minor damage; however, after closer examination, structural damage was found. The National Transportation Safety Board was notified of this damage on July 17, 1996. After the accident, the engine was inspected. During the inspection, there was no evidence found to indicate a mechanical failure or malfunction.
