Bozeman, MT, USA
N1316D
Cessna 170A
Same as Factual Information
The pilot reported that he was flying the airplane over a family member's ranch in a low-altitude, slow flight configuration. He proceeded northbound attempting to regain airspeed when he noticed transmission lines that had previously been visually obstructed to him by the sun. The pilot pulled back on the control yoke attempting to avoid the lines, but the airplane stalled and descended uncontrolled to the ground. The pilot stated that there were no mechanical abnormalities to preclude normal operation of the airplane prior to the accident.
The pilot's inadequate visual lookout and failure to maintain airspeed, which resulted in an inadvertent stall and uncontrolled descent into terrain while manuevering to avoid the transmission lines. The sun glare was a factor.
