Analysis

According to the pilot of the skid-equipped helicopter, he was practicing landing on an 18 foot by 18 foot transport dolly. The pilot reported that during his second landing on the dolly, he landed on the aft end of the dolly and the helicopter slid backwards. He recalled that he heard and felt a thump, pulled pitch, and the helicopter ascended about 5 feet, yawed to the right and he initiated an autorotation and landed. He reported that the bottom of the skids showed scrape marks, "so I must have slid back off the dolly and hit the tail stinger." The tailboom and the vertical stabilizer sustained substantial damage. The pilot reported that there were no mechanical malfunctions or anomalies with any portion of the helicopter during the flight that would have prevented normal flight operations.
