Helicopter pilot reports being bumped on the main skid by a landing C140 as the helicopter is air taxied over the grass to parking. There is no damage to the helicopter and slight damage to the top of the aircraft's wing. The aircraft pilot lost control during the landing roll and departed the runway. The C140 pilot believes the rotor wash caused the loss of control.

Narrative:
I landed our robinson rh-44 helicopter on the runway under clear skies with light winds. It is a privately-owned uncontrolled airfield. On CTAF I made the proper radio calls on downwind; base and final legs. Just past the approach end of the runway; I offset to the left over the grass taxiway and radioed clear of the runway. I had transitioned to air taxi; parallel to the runway; and was headed toward the parking area when I felt a slight bump as an aircraft slid by me; from back to front; on the right-hand (runway) side. I proceeded to parking and landed without difficulty; with no change in the helicopter's handling. An a&P mechanic was present on the field and he inspected the aircraft. No damage was found. He concluded that the bottom of the right skid had been contacted by the other aircraft. I lifted off in a hover while the mechanic inspected the aircraft. No damage; including either skid was found. The other aircraft; a cessna 140; sustained a tear in the covering fabric about two feet inboard from the top left wingtip. The tear was the size of a postage stamp; 3/4 by 1 1/2 inches. The pilot said he lost directional control of the aircraft on landing and departed the runway to the left onto the grass. Tire skids marks on the runway showed a locked right brake with the aircraft still turning left. I believe there were two causes for the event. Primarily; the cessna 140 followed far to close in the landing pattern and should have gone around. There was insufficient lateral clearance on the paved runway and grass taxiway for both of us to safely operate. Second; the cessna pilot said he lost control of his aircraft on landing roll; with the aircraft turning sharply to the left; in my direction; as he approached the helicopter from behind.
