Incident Summary
A flight instructor and a student pilot were conducting a cross-country flight when they decided to divert to avoid building thunderstorms. While on approach to Runway 19, the helicopter experienced a sudden wind gust estimated at 45 knots. The gust caused a loss of tail rotor authority, according to the instructor's written statement. The instructor immediately took control from the student, but the tail rotor struck the runway surface during the maneuver. The instructor was able to level the aircraft and execute a landing without further incident.
Actions Taken
The flight instructor confirmed that there were no mechanical issues with the helicopter prior to the event. After landing, a Federal Aviation Administration (FAA) inspector examined the helicopter to assess the damage.
Inspection Findings
The FAA inspector's examination revealed that one frame tube was broken, the skid cross tube was bent, and one tail rotor blade was damaged. The helicopter was otherwise intact, and the landing was completed without additional problems.
