What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(.19)On November 26, 1999, at 1427 central standard time (CST), a Cessna 310Q, N7762Q, operated by a private pilot, sustained substantial damage when the left main landing gear collapsed during landing on runway 09 (10,002 feet by 150 feet; dry concrete) at the Moline-Quad city airport, Moline, Illinois. The airplane subsequently departed the runway and struck a runway marker before coming to rest. Visual meteorological conditions prevailed at the time of the accident. The personal flight was being conducted under 14 CFR part 91. A visual rules flight plan was on file. The pilot reported no injuries. The cross-country flight originated at downers grove, Illinois, at 1333 CST, and was en route to Moline, Illinois. The air traffic control tower (ATCT) at Moline was advised by the pilot that he had an unsafe gear condition with the left main gear. The pilot made a low pass down runway 23 to have tower controllers look at the landing gear. All three landing gear were down and appeared normal. The pilot was advised of this. The pilot came around and performed a landing on runway 09. On touchdown, the landing gear collapsed and the airplane slid off of the runway. (-23) aircraft advised tower of an unsafe gear condition with the left main gear. The pilot had only two green lights illuminated. The pilot recycled the landing gear with the same results. N7762Q made a low pass down runway 23 to have tower personnel look at the landing gear. The gear was down and appeared normal, which the tower advised the pilot. The pilot decided to attempt a landing on runway 9. Left main gear failed on touch down and collapsed. The aircraft slid off the runway approximately 2000 feet striking a marker sign by the edge of the runway causing substantial damage to the left wing, tip tank, spar, and aileron. (.4) the airplane was on approach. When the pilot extended his gear, he noticed that there wasn't a green light (down and locked) indication on the left main landing gear. The pilot recycled the gear but still didn't get a safe indication. The pilot advised the control tower at Moline, Illinois, of the unsafe gear condition and requested to make a low pass down runway 23 to have tower controllers look at the landing gear. The tower told the pilot that all three landing gear seemed to be down. The pilot came around and p erformed a landing on runway 09. On touchdown, the landing gear collapsed and the airplane slid off the left side of the runway. The airplane struck a runway marker and came to rest in the grass, south of the runway. Examination of the airplane's left main landing gear wheel well showed that the landing gear bellcrank was broken and its pivot bolt was bent, and the inboard rod end of the gear lock turn buckle was broken. No other anomalies were found.
