On March 16, 2025, at 1741 mountain daylight time, a Beech V35 airplane, N7987R, was substantially damaged when it was involved in an accident near Englewood, Colorado. The pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot noticed an alternator caution light and corresponding indication on his primary flight display (PFD) while enroute to his destination. He performed electrical load shedding procedures and arrived at his destination with enough remaining battery power to maintain radio communications and extend the landing gear and flaps. The pilot reported that the landing was normal in all respects, to include the gear indicator light, until the right main landing gear collapsed followed by the collapse of the front and then the left main landing gear. The airplane departed the runway and impacted a taxiway sign and taxi light, resulting in substantial damage to the right wing. Security camera video was obtained that showed the landing gear were extended before touchdown and the initial landing roll appeared normal before the landing gear collapse. The airplane was retained for further examination.
