What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The PIC of N1852H, a Cessna 310 departed St. Charles County Smartt Airport (kset)in st Charles, Missouri to practice some pattern work (take-offs/landings) at the airport. During the take-off he retracted the gear and soon after the gear handle was selected in the up position he heard a loud noise, that he described as a loud bang. The pilot checked the gear position lights. The lights were not illuminated. He pushed the test button and the lights illuminated. The pilot exited the pattern, and flew to a safe area to troubleshoot the problem. All circuit breakers were checked and all were in the correct position, the pilot performed a cycling of the gear. The pilot said he could hear the gear motor running, however the gear position light indicator did not illuminate. The pilot performed a emergency gear extension and the gear position lights indicator never illuminated. The pilot said that he could see in the mirror that the nose wheel was in the down position. The pilot called a mechanic at the airport to come to the runway to visually check that the gear were down as he performed a flyby. The mechanic came to the runway and told the pilot that the gear appeared down, but could not confirm if they were locked in position. The pilot performed a soft field landing lowering the left main and then the right main onto the runway. After touching down onto the runway the aircraft rolled a short distance and then the right wing began to drop. The pilot tried to control aircraft but as the airspeed decreased the aircraft began to veer to the right and came to rest in the grass off the runway.
