(.19) On December 9, 2002, about 1515 pacific standard time, a Cessna T210L, N732HJ, encountered terrain when it veered off the runway after the right main landing gear collapsed during the landing roll at Agua Caliente (L70), California. The us customs service was operating the airplane under the provisions of 14 CFR part 91. The airline transport pilot (ip) and a pilot undergoing pilot-in-command training (put) were not injured; the airplane sustained substantial damage. The local public-use training flight departed nas navy north island (nzy), san diego, California, about 1445. Day visual meteorological conditions prevailed, and no flight plan had been filed. The ip submitted a written statement. While en route to the borrego area for training, the ip simulated an engine failure. The put started emergency procedures and flew to Agua Caliente, the nearest airport. The put flew over Agua Caliente, lowered the gear, and completed the landing checklist. The ip observed the green landing gear down light. He visually checked the right main gear, which appeared to be down. He observed the nose wheel in the mirror that was attached to the right wing, and it appeared to be down. The ip had the put go around and called the maneuver complete. The put completed another traffic pattern and go around and then made a landing. On each go-around the put left the gear in the down position and completed the landing checklist on the downwind leg. On both approaches the ip observed the green gear down light and visually checked the right main gear and nose gear. The ip thought the third approach was on a normal glide path, closer to on speed, but still fast. The put landed the airplane long and a little fast, but in a good attitude with about 200 to 300 fpm rate of descent. When the weight went onto the mains, the ip felt the right side of the airplane settle and looked out the window to see what was wrong. He observed that the right main landing gear was not there. As the left wing came up, the put applied full aileron deflection into the left wing. As the ground speed continued to dissipate, both pilots used full left rudder and left brake to try and keep the airplane on the runway. They didn't have much control of the airplane and it skidded off the edge of the runway into dirt and sand. The airplane slid down a ditch and into a rocky embankment. The ip pulled the mixture prior to leaving the pavement. Both pilots pulled back on the yoke to help get the nose up and cushion the impact. The airplane came to rest upright. They secured the battery and exited using the doors. (-23) on 12/09/02 N732HJ, a Cessna T210L aircraft ws involved in accident while conducting touch and go landings at Agua Caliente Springs Airport, CA. During landing roll out N732HJ'S right main landing gear collapsed. The aircraft sustained substantial damage, however the pilots were not injured. Investigation has revealed the right main landing gear actuator (p/n 9882000-2, s/n 2595) housing cracked. Examination of the failed actuator is ongoing.
