Paul,
You might want to check with the Canadians, they fly a variant of the EH101 in the SAR role (well sometimes). The Cormorant is very much like a Merlin Mk III in that it is non-folding with a ramp (actually it is exactly like a AW510, but that’s another subject). Anyway the point is as they fly the aircraft in the SAR role and therefore do a lot of landings in hospital parking lots etc. I would contact 442 Squadron in Comox, British Columbia, someone form there may be able to help you. Good Luck!
