On February 26, 2000, about 1145 hours Pacific standard time, a Luscombe 8A, N1544K, owned and operated by the pilot, experienced the collapse of its right main landing gear while taxiing to parking after landing on runway 10 at the Selma Airport, Selma, California. The flight was performed under 14 CFR Part 91. The airplane was substantially damaged, and neither the private pilot nor passenger was injured. Visual meteorological conditions prevailed, and no flight plan was filed for the local area personal flight, which originated from Selma about 1055. The pilot indicated that there was no indication of any mechanical problem until after he exited the runway. Suddenly, the right main landing gear axle broke and the airplane nosed down onto its propeller. The airplane had been in operation since about 1947, and it was maintained on an annual inspection basis.
