Narrative:
Ground loop of experimental aircraft. I was acting as PIC of aircraft (thord T18) practicing touch-and-go lndgs at midway airport. Upon returning to eagles nest (2t56) airport for landing, the aircraft was gndlooped. Factors causing the incident were: 1) high approach speed due to throttle stuck off idle. 2) unable to maintain idle (low) speed of engine on rollout after landing. 3) not enough available runway to roll out and brace. Aircraft was forced into drainage area parallel to runway for stoppage. Note: investigation found throttle cable housing clamp to have slippage causing lack of control to carburetor.

Title: EXPERIMENTAL THORD T18 PLT LOST CTL OF THE ACFT DURING LNDG DUE TO A STUCK THROTTLE RESULTING IN A GNDLOOP OFF THE RWY INTO A DITCH. ACFT SUSTAINED MINOR DAMAGE.
Narrative: GND LOOP OF EXPERIMENTAL ACFT. I WAS ACTING AS PIC OF ACFT (THORD T18) PRACTICING TOUCH-AND-GO LNDGS AT MIDWAY ARPT. UPON RETURNING TO EAGLES NEST (2T56) ARPT FOR LNDG, THE ACFT WAS GNDLOOPED. FACTORS CAUSING THE INCIDENT WERE: 1) HIGH APCH SPD DUE TO THROTTLE STUCK OFF IDLE. 2) UNABLE TO MAINTAIN IDLE (LOW) SPD OF ENG ON ROLLOUT AFTER LNDG. 3) NOT ENOUGH AVAILABLE RWY TO ROLL OUT AND BRACE. ACFT WAS FORCED INTO DRAINAGE AREA PARALLEL TO RWY FOR STOPPAGE. NOTE: INVESTIGATION FOUND THROTTLE CABLE HOUSING CLAMP TO HAVE SLIPPAGE CAUSING LACK OF CTL TO CARB.
