On September 8, 1995, about 1600 Alaska daylight time, a tundra tire equipped Maule M-7, N61043, collided with trees during takeoff from a remote area, about 32 miles southeast of Aniak, Alaska. The airplane was being operated as a visual flight rules (VFR) cross-country, on-demand passenger flight under Title 14 CFR Part 135 when the accident occurred. The airplane, operated by Aniak Air Guides, sustained substantial damage. The certificated commercial pilot, and 2 passengers were not injured. Visual meteorological conditions prevailed. Company flight following procedures were in effect. The pilot reported that he was departing a 650 foot long gravel area with hunting clients. The pilot began his takeoff roll in a southeast direction into a 10 knot wind. The pilot indicated that the airplane became momentarily airborne in ground effect. At the end of the takeoff area, the ground sloped downhill and the airplane began to descend. The pilot also indicated that the wind decreased to zero during the takeoff. The aircraft collided with trees beyond the takeoff area and then nosed over.
