On March 16, 2000, at 1356 mountain standard time, a Beech B55, N13RJ, was substantially damaged when the nose landing gear, and right main landing gear, collapsed during landing roll at Ogden-Hinkley Field, Ogden, Utah. The commercial certificated flight instructor (pilot in command) and the private pilot receiving instruction (aircraft owner) were not injured. Visual meteorological conditions prevailed, and no flight plan had been filed for the personal flight being conducted under Title 14 CFR Part 91. The flight originated at Salt Lake City, Utah, approximately 1320. According to the accident report submitted by the aircraft owner, the two pilots had been practicing instrument approaches, and they decided to land. The owner said he made a normal landing but during the rollout, the nose landing gear collapsed. The airplane slid on its nose, then began to veer to the left. The right main landing gear then collapsed. Fuselage bulkheads, stringers, and ribs were damaged. According to the FAA inspector who examined the airplane, the landing gear selector was in the DOWN position, and the flap handle was in the UP position. He said the gear motor, which later tested satisfactory, had to have been working because the gear doors were open. In addition, he said the landing gear torque tubes were bent and not broken.
