The pilot stated he flew out from Panama City-Bay County International Airport to survey a boat located on Deer Point Lake, approximately 8 miles northeast of the airport. With an altitude of about 50 feet and a forward airspeed around 35 to 40 mph he entered a circling maneuver. While flying upwind he reduced engine RPM, and as he turned downwind, he pulled up on the collective, but felt the helicopter sinking instead of climbing. He then looked at the engine instruments and saw the rotor RPM going below 85%. Immediately, he pushed the collective down, but was unable to regain RPM. He deployed emergency floats about 10 feet above the water. The helicopter hit the water "hard" in about 4 feet of water and then rolled onto its right side, due to the right flotation bag being torn off upon impacting the water. The FAA inspector who responded to the accident stated, upon inspection of the helicopter, after recovery, it was found that a pneumatic tubing line had backed off the governor and caused the engine to go to minimum RPM. The governor was last installed 500 hours before the accident and showed signs of a torque seal on the B-nut. The pneumatic line that backed off the fitting is located on the backside of the governor and is hard to see and check for proper torque during routine maintenance.
Probable Cause: Inadequate maintenance inspection resulting in the partial loss of engine power due to a loose pneumatic line on the governor and ditching of the helicopter.
