Analysis

Drg an emergency medical svc (ems/medevac) flt, the plt enctrd stronger headwinds than expected. After delivering a patient, he estimated 12 min of fuel was remaining. Since the flt to his home base would take about 6 min, he elected to return without refueling. While arriving abeam of his destn, a fuel boost pump light illuminated. The plt said he expedited his apch, but at about 50' AGL, a 2nd boost pump light illuminated. The eng then lost power from fuel exhaustion. Subsequently, the helicopter was damaged drg an emergency autorotation (at night).
