NTSB: No engine problems in air show crash

Posted:
STEVENS POINT (WAOW) – The airplane that crashed during an air show in Stevens Point had no mechanical problems that would have prevented normal operation, the National Transportation Safety Board said in a preliminary report.

“All three propeller blades exhibited damage consistent with the engine producing power at the time of impact,” the report issued Wednesday said.

The June 1 crash killed stunt pilot William Cowden, 47, of Menomonie.

The plane, a Yakovlev model YAK-55M, nosedived into the ground just outside the Stevens Point Airport during an aerobatic flight, creating a 2.5-foot deep crater, the report said.

Before the crash, the plane did some spins and went into a near vertical drive before a “momentary increase in airplane pitch,” the report said.

“The post-accident examination of the airplane did not reveal any mechanical anomalies that would have prevented normal operation,” NTSB said in the one-page report.
