Factual Information

On June 5, 1993, at approximately 0845 central daylight time, a Grumman/Schweizer G-164B, N6693Q, was substantially damaged when it collided with a hangar after engine start at a private strip near Kaplan, Louisiana. The airplane was being hand propped by a commercial pilot in preparation for an aerial application flight. There was no flight plan filed and visual meteorological conditions prevailed throughout the area. Neither the pilot, nor a pilot bystander, who was involved, were injured. According to the pilot, he had tied down the tail wheel with a piece of rope and was attempting to hand prop the engine. He further stated that the engine "started slow at first and then accelerated quickly." The rope broke and the 6075 pound airplane started moving under its own power. A pilot on the ground was able to grab the right wing and the airplane yawed nose right. It subsequently collided with a hangar. The pilot stated he had performed the procedure "thousands of times."

Probable Cause and Findings

THE PILOT'S FAILURE TO HAVE THE AIRPLANE PROPERLY ATTENDED DURING START WHEN PEOPLE WERE AVAILABLE. A FACTOR WAS THE INADEQUATE TIE DOWN ROPE.
