The NTSB's narrative final · quoted from the NTSB record
About 10,000 ft mean sea level during a repositioning flight, the flight crew felt a bump/thud in the back of the airplane, which they thought was caused by something falling into the aisle from the lavatory. The flight crew observed that the landing gear unsafe light was illuminated. The flight crew stated that they followed emergency/abnormal airplane checklist items and reset the landing circuit breaker, which did not retract the landing gear. Then, the crew lowered the landing gear, which resulted in three green landing gear position lights. They continued the flight to the destination with the landing gear extended where they landed the airplane. During landing rollout and after applying moderate braking, they felt the right main landing gear collapse, which then punctured the right wing and resulted in substantial damage to right wing. Postaccident examination revealed the aft main landing gear trunnion pin for the right main landing gear was not properly installed during the recent maintenance as the aft trunnion pin was not installed far enough to allow the retaining roll pin to engage and retain the trunnion pin. The pilot reported and maintenance records showed that maintenance performed by the aircraft manufacturer’s service center, which included the reinstallation of the main landing gear trunnion pin, occurred 2.9 hours before the accident. According to the manufacturer’s maintenance manual installation procedures, maintenance personnel are required to make sure the aft end of the trunnion pin is at least 2.0 inches (50.8 mm) forward of the aft spar fitting to verify proper installation. The Civil Aviation Accident and Incident Investigation Commission (CIAIAC) of Spain investigated a similar accident that occurred on May 4, 2018, as documented in CIAIAC Report A-012/2018. As a result of the investigation, the aircraft manufacturer published a mandatory service letter (SL525C-32-12) to do an inspection of the aft main landing trunnion pins for proper installation.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number CEN25LA402.
