NTSB summary
HISTORY OF FLIGHT On August 18, 2004, about 0810 Alaska daylight time, a wheel-equipped experimental/homebuilt, Hudson Hiperbipe SNS-7 airplane, N898DH, was destroyed by impact and postimpact fire when it collided with tree-covered terrain following a loss of control during initial takeoff climb from the Wolf Lake Airport, Palmer, Alaska. The airplane was being operated as a visual flight rules (VFR) local area personal flight under Title 14, CFR Part 91, when the accident occurred. The certificated private pilot, the sole occupant, received fatal injuries. Visual meteorological conditions prevailed, and no flight plan was filed. The flight originated about 0810 from the Wolf Lake Airport. During on-scene interviews with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on August 18, a witness located at the Wolf Lake Airport reported that the airplane departed runway 24, and climbed to about 200 to 300 feet above the ground. The witness reported that as the airplane approached the departure end of the runway, it initially turned about 90-degrees to right of the runway centerline, immediately followed by a tight 360-degree turn to the left, circling the departure end of the runway. The witness said that as the airplane continued the tight 360-degree left turn, the wings rolled and continued to roll until the airplane was inverted. The nose of the airplane abruptly pitched down, and it descended into a large stand of trees at the departure end of the runway, followed by a large plume of black smoke.

Probable cause
The pilot's failure to maintain control of the airplane, which resulted in an uncontrolled descent and subsequent in-flight collision with trees. A factor associated with the accident was a low altitude maneuver preformed by the pilot just after takeoff.
