A witness reported hearing the airplane circling but could not see it due to fog. The witness stated that the engine was running continuously until the sound of impact was heard.
Wreckage Examination
Post-accident examination of the wreckage revealed no preimpact mechanical malfunctions, indicating the airframe and engine were likely functioning normally before impact.
