While I was on a repair station maintenance test flight for avionics verification I experienced an Engine Two Chip warning 3 minutes after departure. No secondaries. I attempted three times; unsuccessfully; to burn the chip; then turned back to the airport and adjusted flight controls to establish OEI [One Engine Inoperative] flight conditions; retarded Number 2 power lever to idle; trimmed NR [Rotor RPM] to 100% and was cleared by Tower to land Runway 28; thence direct to the ramp. I did not declare an emergency. Established OEI landing profile to Runway 28 and shut down the Number 2 Engine when over the runway. Performed run-on landing to the grass between Taxiway A and Runway 28. No injuries to crew and passengers or damage to aircraft. Repair station personnel moved aircraft back to hangar for required follow-on maintenance. No chips or fuzz found on the chip detector plugs.
A BK117 pilot on a maintenance assessment flight encountered a chip warning in the Number Two Engine. He performed appropriate preparatory procedures; shut down the engine and performed a run-on landing on the grass between the runway and parallel taxiway at the departure airport.
