Probable cause
The loss of engine power as a result of the backing off of the PC air line "B" nut due to the improper installation by the company maintenance personnel. Contributing factors were the inadequate preflight by the pilot and the lack of suitable terrain for the forced landing.

Read the full NTSB narrative
During cruise flight, approximately 400 feet agl, the helicopter experienced a "sudden" loss of power. The pilot initiated an autorotation to a residential street. During the forced landing, the main rotor blades struck trees that over hung the street. Subsequently, the helicopter touched down "hard" and slid to a stop. An examination of the helicopter revealed the B-nut on the PC pneumatic line from the power turbine governor tee fitting to the fuel control, at the fuel control end, was backed off from the fitting. When viewed initially, the B-nut appeared to be connected, but when moved by hand, it dislodged from the fuel control connection. Further examination revealed the whole engine was void of the required torque striping on all B-nuts. Examination of the maintenance records revealed the helicopter accumulated 42.6 hours since the last 100-hour maintenance inspection that was performed on March 29, 2002.
