Aircraft Accident/Incident Report
Fallon, Nevada 89406

NTSB Narrative Summary Released at Completion of Accident
The certified flight instructor (CFI), seated in the front seat, reported that the airplane started to drift to the right during the landing roll. The student pilot, seated in the rear seat, applied left rudder to counteract the drift, but the airplane continued to the right. The CFI took control of the airplane and applied full left rudder and full power; however, the airplane continued to the right until the left main landing gear collapsed and the airplane nosed over. The airplane was equipped with dual lap belt aerobatic harnesses. Postaccident examination revealed that, when full left rudder was applied, the front seat pilot's upper lap belt caught on the rear seat right rudder/brake pedal assembly and activated the right brake. As a result of this finding, the manufacturer issued an Airplane Flight Manual Supplement (AFMS) that provided guidance for pilots to examine the front seat lap belts for proper tension and clearance from the rear seat rudder pedals during their prestart and preflight checks. In addition, the Federal Aviation Administration issued a Special Airworthiness Information Bulletin (SAIB CE-10-39) that addressed proper installation of the dual lap belt system and informed pilots of the issuance of the AFMS pertaining to the lap belts.
NTSB Probable Cause Narrative
Interference between the front seat lap belt and the rear seat rudder/brake pedal assembly that prevented normal operation of the rudder/brake system, which resulted in the pilots’ inability to maintain directional control.
