The single engine, two seat, jet airplane impacted the ground while pulling out of a low level loop. The airplane was practicing low level team aerobatics with two other similar jet airplanes. The established hard deck for the practice was 1,000 feet. The lead jet entered a loop maneuver at about 1,500 feet and impacted the ground while pulling out at the bottom of the maneuver. During the end of the maneuver the wings rocked and the nose pitched down. Examination of the ejection seat mechanism disclosed no evidence that the pilot attempted to eject from the airplane. No evidence of a control system malfunction was found and the damage to the engine was consistent with it developing significant power at ground impact.
Probable Cause: the pilot's failure to maintain adequate terrain clearance while performing low level aerobatics.
