Pilot of a sightseeing biplane lost control during takeoff due to aircraft veering unctlably to the left and pulled power off for rejected takeoff. The aircraft then continued into a ground loop and came to stop without damage or injury to the aircraft or occupants.

Narrative:
Upon takeoff roll, I noticed the airplane heading was 260 degrees and as power was applied the direction of the plane was veering to the left. I tried to straighten the direction of the plane out. When I found it wouldn't, I immediately pulled the power and mixture off which caused the airplane to ground loop as it was going to the left anyway. Upon inspecting the right wheel and strut, we found the cable that stops the strut and landing gear from hanging like a pendulum under the fuselage had broken and we think the loose gear on one side as it swung down acted as a nose gear and caused the plane to veer to the left, as the other wheel became lighter and lost traction with the ground. Pilot and two passenger walked away without incidence. As a precautionary measure we are removing the fairing covers over the struts which will expose the cables that hold the landing gear and wheels from falling under the fuselage.
Original NASA ASRS Text
Title: PLT OF A SIGHTSEEING BIPLANE LOST CTL DURING TKOF DUE TO ACFT VEERING UNCTLABLY TO THE L AND PULLED PWR OFF FOR REJECTED TKOF. THE ACFT THEN CONTINUED INTO A GND LOOP AND CAME TO STOP WITHOUT DAMAGE OR INJURY TO THE ACFT OR OCCUPANTS.
Narrative: UPON TKOF ROLL, I NOTICED THE AIRPLANE HDG WAS 260 DEGS AND AS PWR WAS APPLIED THE DIRECTION OF THE PLANE WAS VEERING TO THE L. I TRIED TO STRAIGHTEN THE DIRECTION OF THE PLANE OUT. WHEN I FOUND IT WOULDN'T, I IMMEDIATELY PULLED THE PWR AND MIXTURE OFF WHICH CAUSED THE AIRPLANE TO GND LOOP AS IT WAS GOING TO THE L ANYWAY. UPON INSPECTING THE R WHEEL AND STRUT, WE FOUND THE CABLE THAT STOPS THE STRUT AND LNDG GEAR FROM HANGING LIKE A PENDULUM UNDER THE FUSELAGE HAD BROKEN AND WE THINK THE LOOSE GEAR ON ONE SIDE AS IT SWUNG DOWN ACTED AS A NOSE GEAR AND CAUSED THE PLANE TO VEER TO THE L, AS THE OTHER WHEEL BECAME LIGHTER AND LOST TRACTION WITH THE GND. PLT AND TWO PAX WALKED AWAY WITHOUT INCIDENCE. AS A PRECAUTIONARY MEASURE WE ARE REMOVING THE FAIRING COVERS OVER THE STRUTS WHICH WILL EXPOSE THE CABLES THAT HOLD THE LNDG GEAR AND WHEELS FROM FALLING UNDER THE FUSELAGE.
