NTSB summary
HISTORY OF FLIGHT On June 19, 2004, at 1806 central daylight time, a Monocoupe 90AL-115, N1161, owned and operated by a private pilot, was destroyed when it impacted terrain while maneuvering near St. Paul, Missouri. Visual meteorological conditions prevailed at the time of the accident. The personal flight was operating under the provisions of 14 Code of Federal Regulations Part 91 without a flight plan. The pilot and his passenger were fatally injured. The local flight departed Creve Coeur Airport (1H0), near Maryland Heights, Missouri, at 1755. Aircraft radar track data was obtained from the Federal Aviation Administration (FAA), St. Louis Approach Control facility. Primary radar returns were used to reconstruct the accident flight because the airplane was not equipped with a transponder. No altitude information is available with primary radar data. The track data was plotted on a St. Louis Terminal Area Chart and showed N1161 departing 1H0 from runway 34, then continuing north-northwest toward Peruque, Missouri. The plotted data then showed the accident airplane performing several 180-degree turns approximately 1.8 nm northwest of Waldmeister Farm Airport (45MO). The turns were completed within a 1.4 nm square area. The airplane's calculated ground speed varied between 74 and 146 knots during the series of 180-degree turns. The data indicated that the ground speed decreased to approximately 75 knots when the airplane was turning. The ground speed increased to 111-146 knots during the straight flight paths between turns. The accident site was located approximately 1,500
Probable cause
The pilot's failure to maintain altitude/clearance from the terrain while maneuvering.
