The NTSB's narrative preliminary · quoted from the NTSB record

On August 27, 2024, about 1845 mountain daylight time, a Beech J35, N8350D, was substantially damaged when it was involved in an accident near Belgrade, Montana. The pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. According to the pilot, a new pitch trim servo was recently installed as part of the autopilot system update on the airplane prior to the accident flight. The pilot completed a post-maintenance preflight and departed without incident.  The pilot started that he conducted a straight-in approach to runway 30 at Bozeman-Yellowstrone International Airport, Bozeman, Montana, about 45-minutes after departure. During the landing flare, he felt the control yoke "jam up" and that it felt as though it "broke free" when he increased aft backpressure on the yoke. The control yoke "jammed up" a second time shortly after the pilot attempted to level the aircraft for landing, and when he applied additional forward movement, the control yoke "broke free" again. Subsequently, the airplane landed hard. A post-accident examination of the airplane revealed that the lower engine mount structure was substantially damage. Additionally, one of the pitch servo bridle cable clamp assemblies (figure 1) appeared to be binding on bulkhead assembly, station 179, a control cable tunnel guide. Figure 1. View of bridle cable clamp slightly aft of the bulkhead assembly at station 179. The airplane was recovered to a secure location for further examination.

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 docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site 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 WPR24LA323.
