On July 18, 2021, about 0855 mountain daylight time, a Beech 35-C33 airplane, N18AR, was substantially damaged when it was involved in an accident near the Vance Brand Airport (LMO), Longmont, Colorado. The pilot and passenger sustained serious and minor injuries, respectively. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.
The pilot reported that the preflight inspection and run-up were normal. However, after takeoff from runway 29, the airplane climb performance was not as expected. He initiated a shallow right turn to avoid a house off the departure end of the runway, and the airplane unexpectedly entered an aerodynamic stall.
The airplane impacted a hay field and came to rest about 1/3-mile from the departure end of the runway. It had sustained damage to the fuselage and engine mount. Postaccident airframe and engine examinations are planned.
