Aircraft involved
Probable cause & findings
the pilot in command's not maintaining control of the airplane and his inadvertently allowing the airplane to enter a stall. A factor was the undetermined loss of engine power.
Factual narrative
On July 13, 1998, at 1940 central daylight time, a Canadian Car & Foundry Harvard MK IV, N5101W, piloted by a private pilot, sustained substantial damage when it impacted the terrain, following a loss of control during takeoff, near Dyersville, Iowa. Visual meteorological conditions prevailed at the time of the accident. The 14 CFR Part 91 personal flight was not operating on a flight plan. The pilot and one passenger reported minor injuries. The flight was originating at the time of the accident with the intended destination of Dubuque Regional Airport, near Dubuque, Iowa. The pilot stated in his written statement that the engine lost power during initial climb, after which the airplane "... turned to the right in a nose up attitude stalled, and impacted on the nose and right wing." An inspection of the airplane subsequent to the accident did not reveal mechanical problems with the engine. The airplane's flight control continuity was verified. The pilot said that there was a loss of engine power during initial climb after takeoff. He said that the airplane turned to the right in a nose up attitude, stalled, and impacted the terrain. An examination of the airplane after the accident failed to reveal any mechanical anomalies with the engine or flight controls.
