Incident Overview
An aircraft impacted a Quonset-type building while apparently executing an unusual approach for landing. The aircraft was described as a high-wing, fixed-gear type, yellow and white in color, similar in configuration and color to N5277X.
Witness Accounts
One witness observed the aircraft make a low south-to-north pass over the runway, then pull up into a loop that culminated in the impact with the Quonset building.
Another witness saw the aircraft flying south to north at an estimated altitude of 100–150 feet. This witness then observed the aircraft perform a half roll, followed by a steep descent toward the ground.
Additional Report
At 1030, it was reported that an aircraft matching the description—high wing, fixed gear, yellow and white, similar to N5277X—was making low passes over some ice fishermen on a lake.
Conclusion
The source does not provide a stated probable cause for the accident.
