What happened
On May 2, 2008, a Robinson R22 departed from Linz-Hörsching Airport operating under Visual Flight Rules (VFR). During the return leg of the flight, while passing over a property located at Lobenstein 33, the helicopter began experiencing unexpected yawing motions.
In response to these instabilities, the pilot initiated an emergency landing. The aircraft subsequently made a hard landing on a nearby meadow. The pilot sustained no injuries, but the aircraft suffered substantial damage.
The investigation
Subsequent analysis of the flight profile focused on the maneuvers performed immediately prior to the impact. The investigation examined the sequence of control inputs and the aerodynamic behavior of the rotor system during the final approach to the landing site.
