Registration: N789WF
C/n / msn: D-9956
Fatalities:Fatalities: 0 / Occupants: 4
Aircraft damage: Substantial
Category:Accident
Location:Wilmington International Airport (KILM), Wilmington, NC -   United States of America
Phase: Take off
Nature:Private
Departure airport:Wilmington, NC (ILM)
Destination airport:Gainesville, FL (GNV)
Investigating agency: NTSB
Narrative:
The pilot private reported that he filled each of the fuel tanks and loaded the six seat, single-engine airplane with four occupants and baggage before attempting to depart on the cross-country personal flight. During the attempted takeoff, the airplane's nose pitched abruptly upward and turned left. The pilot continued the takeoff as the airplane departed the runway surface. The airplane then bounced several times, entered an aerodynamic stall, and subsequently struck the airport perimeter fence, which resulted in substantial damage to the airframe.
After the accident, the pilot was unable to precisely account for the airplane's loading; an estimated calculation indicated that the airplane's total weight was well above, and that its center of gravity (CG) was well aft of, those specified by the airframe manufacturer and the provider of the aftermarket fuel tanks with which the airplane was equipped. Additionally, the elevator pitch trim was found set to a position that would have increased the airplane's tendency to pitch up, especially given its high weight and aft-located CG. The airplane's sudden pitch up during the takeoff roll was likely due to its improper loading and trim configuration, and its lateral departure (left turn) from the intended takeoff path was likely due to a known performance phenomena associated with single-engine airplanes operating at high power and low airspeed at takeoff.
Probable Cause: The pilot's improper loading of the airplane, which resulted in a sudden pitch up during the attempted takeoff, the pilotís subsequent loss of directional control, and an aerodynamic stall.
