The helicopter. operating in support of flood relief, made a forced landing and tailboom was severed.
Probable cause of the Accident:
PIC while carrying out approach and landing under strong tail wind conditions, could not control the high rate of descend with the available reserve power (Max collective power). The helicopter entering into vortex ring state, becoming uncontrollable which eventually resulted into the heavy landing accident.
Deployment of cockpit crew to operate in hilly/mountainous terrain by PHL operations without requisite hill flying training/recurrent training is a contributory factor to the accident.
