## Discrepancy

HELICOPTER WAS LIFTING OFF STAGING AREA WITH 150FT LONGLINE AND APPROX 2600 LBS EXTERNAL LOAD.  WHEN LOAD WAS APPROX 30FT OFF THE GROUND THE PILOT HEARD A LOUD "POP.  NR1 ENG HAD FAILED.  EXTERNAL LOAD WAS JETTISONED, A SINGLE ENGINE FAILURE EMERGENCY LANDING INTO THE STAGING AREA WAS PERFORMED WITHOUT FURTHER INCIDENT.  PRELIMINARY INVESTIGATION REVEALED THAT NR 1 ENG GAS GENERATOR CASE HAD SEPERATED FWD AND AFT OF THE FUEL FLOW DIVIDER AND INBD AND UPWARDS TOWARDS THE TAIL ROTOR DRIVESHAFT TUNNEL.  A NR OF FUEL NOZZLE TUBES AND ENGINE OIL TUBES WERE BENT AND DAMAGED AS WELL AS THE TAIL ROTOR DRIVESHAFT TUNNEL WAS DEFORMED.
