What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On 03-24-2013 life flight 1, N577LF, responded to a scene call in Atmore, Alabama. The ceiling and visibility were unlimited. The wind was out of the west. The aircraft landed at the scene at 17:25. The helicopter was parked facing south toward the ambulance. The engine was brought back to idle. The cyclic was centered with the friction applied. The aircraft was shut down and the patient access door was opened for the medical crew to unload the stretcher. A gust of wind caught the open door causing the strut assembly (compensating cylinder) to fail at the attach point on the airframe, which allowed the right, front cabin door to swing upward and make contact with the main rotor. The door was damaged from the corner of the door to the window seal. All three blades had scratches on them from contact with the door. The rotor was at less than 100 RPM with the rotor brake applied when contact was made with the door. The checklist was completed for shutdown. The aircraft was taken out of service and the patient was transported by ambulance.
