On July 21, 2001, at 1215 central daylight time, a Cessna T210N single-engine airplane, N6114A, was substantially damaged during landing at the Amarillo International Airport near Amarillo, Texas. The airplane was registered to and operated by the pilot. The private pilot, sole occupant of the airplane, was not injured. Visual meteorological conditions prevailed, and no flight plan was filed for the 14 Code of Federal Regulations Part 91 personal flight. The flight originated from Sugar Land, Texas, at 0900. According to the pilot, he put the landing gear control switch to the down position when he was 5 miles from landing. Prior to turning final, he "verified" that the gear was extended by looking out the window and into the mirror under the right wing. As the airplane was touching down on runway 22, the gear warning horn sounded. After touchdown, the main landing gear collapsed, and the nose landing gear remained extended. When the "wings lost lift," the airplane tilted to the left, the left wing struck the runway, and the airplane turned 90 degrees and exited the runway. The pilot stated in the Recommendation (How could this accident have been prevented) section of the Pilot/Operator Aircraft Accident Report, NTSB Form 6120.1/2, that the accident could have been prevented by better training for the pilot on the failure of the gear to extend and lock, and practice of manual gear extension. An examination of the airplane by the FAA inspector, who responded to the accident site, revealed that the left wing tip, left horizontal stabilizer and left elevator were damaged. A subsequent examination of the cockpit revealed "a tripped [landing] gear motor circuit breaker." The circuit breaker was reset, and the gear was successfully pumped down by hand using the emergency gear extension mechanism.
