On August 20, 1993, a Champion 7GCAA (registration N11027) operated by Christensen, Darrell D. was involved in an aviation accident near Wilber, NE. Investigators recorded the probable cause as: The loss of engine power during initial climb for reasons that could not be determined, as postaccident examination and engine test run revealed no evidence of preimpact mechanical malfunction. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
An aircraft experienced sudden power loss shortly after takeoff, leading to a forced landing among trees with no mechanical defects found during post-accident inspection.
What happened
The pilot reported that the airplane engine sputtered and subsequently lost power while the aircraft was approximately 100 to 150 feet above the ground. This event occurred during the initial climb phase of the flight. Following the loss of power, the pilot attempted an emergency descent or forced landing. During this maneuver, the airplane struck trees.
The investigation
A postaccident examination of the aircraft was conducted to determine the cause of the incident. Additionally, an engine test run was performed on the recovered powerplant. These inspections revealed no evidence of any mechanical malfunction that would have occurred prior to impact.
Probable cause
The loss of engine power during initial climb for reasons that could not be determined, as postaccident examination and engine test run revealed no evidence of preimpact mechanical malfunction.
