On June 16, 1994, at 0815 mountain daylight time, a Cessna T210N, N199CH, suffered an engine failure while in the pattern at Santa Teresa Airport, New Mexico. During the ensuing forced landing, on a taxiway, the aircraft went off the taxiway onto unprepared terrain and incurred substantial damage. The pilot and passenger were not injured. Visual meteorological conditions prevailed and no flight plan was filed for this local flight. According to the pilot, he had completed one touch-and-go and was entering down wind for runway 28 when the engine ceased to operate. Attempts at a restart were unsuccessful and a forced landing was conducted at 90 degrees to the runway/taxiway with initial touchdown on a runway exit. Ground roll was across the runway, a grass area, and into a ditch which was approximately 60 feet wide and 5 feet deep. According to the FAA inspector who examined the aircraft, the engine driven fuel pump would not pump fuel during his examination.
