Incident Overview
Two aircraft, an RV6A and a PA-16, were flying in the traffic pattern for landing on runway 27 right. The air traffic controller issued a base leg call to the RV6A pilot, who was slow to respond. Shortly after, the controller called the base leg for the PA-16 pilot.
Sequence of Events
The controller then observed the PA-16 overtaking the RV6A on final approach and instructed the RV6A pilot to side-step to runway 27 left. The RV6A pilot did not acknowledge or comply with this instruction. The controller subsequently instructed the PA-16 pilot to maintain a higher altitude, but the PA-16 pilot also did not respond.
Collision and Impact
The controller saw the nose of the RV6A pitch up violently, and both aircraft subsequently collided with the ground. Post-impact examination revealed that the PA-16's left main landing gear had struck the upper surface of the RV6A's empennage behind the cabin area, and the PA-16's propeller had impacted the RV6A's cockpit area.
