Factual Information

On Saturday evening, August 7, 1993, at 2030 mountain daylight time, a Cessna C-188, N9802V, operated by the pilot, impacted terrain at the Campbell Ranch Airstrip, Marion, Montana, during takeoff.

The commercial certificated pilot was not injured in the accident. The aircraft was substantially damaged. There was no fire. The pilot reported that while on initial climb after takeoff from his private airstrip on runway 10, the aircraft stalled/mushed after it cleared saw horses at the end of the strip, descended and impacted terrain off the end of the strip. He said the wind socks on the strip indicated the wind was calm at the time of the accident. The surface aviation weather observation taken at Glacier International Airport, located 35 miles northeast of the Campbell Ranch Airstrip, at 1953, was recorded as clear skies, visibility 50 miles, altimeter 29.68 inches Hg., temperature 75 degrees F., dew point 43 degrees F., wind 240 degrees at 7 knots.
