What happened
A flight instructor was conducting an annual proficiency check in a helicopter when the crew engaged in a simulated anti-torque pedal emergency procedure. During this maneuver, which involved simulating a stuck pedal, the flying pilot attempted to land on a hard-surfaced runway while the aircraft maintained significant yaw.
The aircraft touched down twice during the process. On the second touchdown, the helicopter landed with enough force to cause structural damage to the fuselage and the drive train components. Both pilots on board held flight instructor and airline transport certificates; there were no injuries reported.
Findings
The investigation determined that the flying pilot attempted to land the aircraft while it was still experiencing significant yaw during the simulated emergency. Additionally, the check pilot did not intercede or take any remedial action while the flying pilot was attempting the landing under the simulated stuck pedal conditions.
