Narrative:

I was on a final stabilized VFR approach to runway 18 at mdq and just about to flare when I encountered significant turbulence from a chinook helicopter; both rotors turning; that was waiting to takeoff from a spot on the grass between the touchdown zone of runway 18 and the parallel taxiway. The turbulence hit me just at about the flare and I was barely able to salvage a very hard landing. This is an airport that has significant helicopter activity. I believe some airport rules should be considered to restrict this type of helicopter operation near the approach end of the active runway as an effort to eliminate/minimize such turbulence.
