On September 23, 1993, at approximately 1345 Pacific daylight time, N736ZV, a Cessna 182RG, sustained substantial damage when the main landing gear collapsed after landing at Pearson Airpark, Vancouver, Washington. The private pilot and his two passengers were uninjured. A flight plan had been filed from The Dalles, Oregon, which was the last departure point for the flight, which was conducted under visual meteorological conditions. There was no report of the ELT actuating. The pilot stated that the main landing gear appeared to be fully extended prior to touchdown, and that he had a green light. During the rollout, the main landing gear collapsed, and the aircraft rolled to a stop with the nose landing gear still extended. After the aircraft stopped rolling, the left wingtip settled toward the ground, allowing the horizontal stabilizer to sustain bending damage. FAA inspectors inspected the aircraft and found no evidence of a mechanical failure in the landing gear system. The pilot was interviewed by telephone, but failed to provide a written accident report.
