The pilot of the homebuilt Welborn Pulsar XP reported that upon arrival at the Prineville airport he conducted a successful touch and go to runway 28. During the second landing the throttle cable disconnected and the throttle went to full power. The aircraft bounced back into the air and then returned to the runway surface, and the pilot then shut the engine down as the aircraft began veering left. The pilot was unable to prevent the aircraft from departing the runway at which time all three landing gear collapsed. Local winds were reported as 020 degrees at 5 knots.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The disconnection of the throttle cable on landing resulting in the aircraft's engine going to full throttle and the pilot's subsequent failure to maintain directional control after securing the engine during the landing event.
