Aircraft: STOL CH701. Injuries: 1 Fatal. Location: Pulaski, Wis. Aircraft damage: Destroyed.
What reportedly happened: The private pilot, 67, was the builder of the experimental, amateur-built airplane. The accident was the airplane’s first flight.
It was climbing out when it veered to the left and narrowly cleared a tree line. The plane entered a steep climb, leveled off, then entered a left turn and then a second steep climb.
It continued in the left turn until it entered a steep downward spiral, crashing about 800 feet from the threshold of the runway.
No pre-impact structural issues were found during the investigation.
Probable cause: The pilot’s lack of aircraft control during initial climb, which resulted in an aerodynamic stall.
