Analysis

During flt, the eng lost power & the plt began an autorotative landing in a parking lot. During the apch, he maneuvered to avoid a 100 ft crane. As the helicopter was approaching the intended touchdown point, a vehicle was driven into the flt path of the acft. To avoid the vehicle, the plt increased the collective to extend the glide path. Subsequently, the helicopter lost rotor RPM before touchdown & landed hard. An exam revealed that an improper part (an oil line) had been substituted for the 'compressor to fuel control pressure sensing' line (pn 6848471). The line had fractured at a b-nut which resulted in a loss of power.
