On December 31, 1994, at 1725 mountain standard time, a Cessna P210N, N6106W, was substantially damaged while landing near Albuquerque, New Mexico. The commercial pilot and his passenger were seriously injured. No flight plan was filed and visual meteorological conditions prevailed throughout the area for the personal night cross country flight. According to the Federal Aviation Administration (FAA) inspector, the flight originated in Monterey, Mexico, with an intermediate stop in El Paso, Texas, to clear customs and refuel the airplane. Upon arrival at their destination, the pilot executed a visual approach to Runway 17 at the Coronado Airport. According to the passenger, the airplane touched down very smoothly in the grassy area between the active runway and the parallel taxiway. The passenger stated that he unbuckled his seat belt as soon as the airplane touched down. After rolling for approximately 300 feet, control was lost after the airplane impacted a taxiway embankment. Official sunset was 1705. The airport was equipped with pilot controlled lighting. The pilot of a Luscombe landing behind N6106W, stated that the runway lights were off at the time of the accident, and he had to activate the system prior to his landing. Blank copies of NTSB Form 6120.1/2 were mailed to the pilot on two occasions. None were returned.
