Analysis

A Cessna 172I collided with mountainous terrain during instrument meteorological conditions. A fire was reported in the accident area. Fireman were unable to pinpoint the location of the fire due to low ceilings and fog obscuring the mountain tops. A helicopter was dispatched to help locate the fire and had to turn around due to the weather conditions. The fire was eventually extinguished during night fall. The airplane accident was not discovered as the cause of the fire until daylight the following day. Two weather observation facilities located at two local airports which bracketed were reporting a 2,000 ft overcast ceiling. One was located five miles away at an elevation of 650 ft MSL. Another was located 14 miles away at an elevation 96 ft MSL. The elevation of the accident site was about 1,485 ft.
