## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) WHILE LIFTING A SLING LOAD CONSISTING OF A 430 POUND AIR VENTILATION VAN TO THE ROOF TOP OF A WINDOW MANUFACTURING PLANT THE AIRCRAFT EXPERIENCED A LOSS OF POWER AND LANDED ON ITS SIDE ON THE ROOF. THE AIRCRAFT WAS HOVERING AT APPROXIMATELY 90 FEET ABOVE THE LOAD POSITIONING THE FAN OVER AN OPENING WHEN THE POWER LOSS OCCURRED. THE PILOT MANEUVERED TO AVOID THE PEOPLE UNDER THE AIRCRAFT WHO WERE POSITIONING THE FAN INTO PLACE AND ATTEMPTED TO RELEASE THE LOAD. THE AIRCRAFT LANDED HARD AND BOUNCED SIDEWARD THE LENGTH OF LIFTING CABLE. THE CABLE WITH ITS ATTACHED LOAD PREVENTED THE HELICOPTER FROM LANDING LEVEL WHICH RESULTED IN THE HELICOPTER ROLLING ON ITS SIDE. THE ROTORBLADES WERE BENT UP AT AN EXTREME ANGLE WITH VERY LITTLE ROTATIONAL DAMAGE. THE CAUSE OF THE POWER LOSS HAS NOT BEEN DETERMINED. EXTERNAL INSPECTION OF THE ENGINE DID NOT REVEAL ANY OBVIOUS CAUSE. THE ENGINE IS BEING REMOVED AND RETURNED TO THE MANUFACTURER FOR FURTHER ANALYSIS.
