NTSB summary
HISTORY OF FLIGHT On September 19, 1998, at 1330 central daylight time (cdt), a Barklage Revolution Mini 500, N611AB, operated by a commercial pilot, was destroyed when on initial climb, the helicopter's engine lost power. During the subsequent emergency landing, the helicopter impacted into a soybean field. Visual meteorological conditions prevailed at the time of the accident. The personal flight was being conducted under 14 CFR Part 91. There was no flight plan on final. The pilot sustained serious injuries in the accident, and passed away six days later. The cross- country flight originated at Cahokia, Illinois, at 1323 cdt, and was en route to St. Charles, Missouri. A witness, standing in the parking lot on the northeast side of Helicopters, Incorporated's main hangar, at St. Louis Downtown Parks Airport, Cahokia, Illinois, said that he heard "a Mini 500 either running or hovering behind the hangar." The witness watched the helicopter fly around the south side of the hangar. It made a wide, level turn. The witness estimated that the helicopter was 100 to 150 feet above the ground when it passed in front of him. The helicopter came around the hangar and the parking lot, and then headed toward the north-northeast, toward the river (Mississippi River) and the city (St. Louis). It was approximately 200 feet above the ground. The helicopter was higher than the telephone lines which ran northeast of the airport. "He was level and climbing, going away from me when all of a sudden, the sound (engine sound) went quiet, followed by a pop. It was not a loud pop." The witness said
Probable cause
A loss of engine power due to cold seizure of the power-takeoff cylinder. A factor contributing to the accident was the power lines.
