Analysis

The pilot stated that he and his passengers attempted to remove as much snow as possible from the aircraft and that he was confident that the propeller blast would blow away whatever snow remained. Although the wind at surrounding stations was generally reported out of the northwest the pilot reported the wind out of the east on takeoff. The pilot elected to takeoff with 10 degrees of flaps, the manual states to use 20 degrees to reduce ground run on soft field takeoffs. During takeoff the aircraft was held on the runway until 70 mph IAS before rotation was attempted. This is 10 mph over normal rotation speed and was used to compensate for the stated tailwind. The aircraft lifted briefly off the ground then settled back on the runway. Power was pulled and the aircraft slid off the end of the runway and nosed down into the bank of a small creek.
