Analysis

The flt departed the 34th street heliport on a local sightseeing flt to the statue of liberty & return. As the flt crossed lower manhattan, about 1/4 mi from the east river, the plt heard the low RPM audio signal. He lowered the collective & rotor RPM returned to the green. While turning to the east river the generator-out & eng-out lights' illuminated. The floats were inflated & the helicopter contacted the water in a level attitude. The nose then contacted the water & the chin bubble broke. Water entered the helicopter & it rolled right to an inverted position. Investigationdisclosed that the filter line between the compressor scroll & the power control unit had broken at the filter end. A visual examination of the failed pc line & the b-nut fitting disclosed that the fracture occurred at the outboardend of the ferrul.
