Confidence Rating: Accident investigation report completed and information captured
The lateral cyclic friction was on prior to departure, and the helicopter landed hard shortly after takeoff. After the pilot's first flight, the helicopter underwent a hot refueling and the passengers were loaded onboard for the pilot's second flight. The pilot performed her pretakeoff checklist items, which included releasing the control frictions and performing a freedom of control check. The pilot then demonstrated to the front seat passengers where to position their feet by bringing her right foot aft. She then obtained tower clearance and began the takeoff. During the takeoff, the cyclic was locked and she could not move it. She attempted to control the helicopter using trim but shortly thereafter, the helicopter impacted the ground. Upon impact, the pilot reached down and released the lateral cyclic friction. The Federal Aviation Administration (FAA) inspector examined the lateral cyclic friction system installation and operation and noted no mechanical anomalies. The FAA inspector did note that if he brought one foot farther aft than is done in normal operation, an inadvertent application of the lateral cyclic friction might result.

Probable Cause: Inadvertent application of the lateral cyclic friction, which resulted in a loss of control and subsequent hard landing.
