This does not exactly answer your question, though you may find helpful. There are only a couple of locations in the US that human class D rescues are carried out by civilian operators. One is in Denali national park in AK, the current company with the contract is TEMSCO based in Ketchikan, AK. They are using a AS350 B3. Although TEMSCO also has some bell mediums, not sure if they are Class D certified. The other place that I am aware of where these recuses are done on a regular basis, is in the Tetons, out of Jackson Hole, WY. Last I knew Helicopter Express, out of George had this contract. They had a Bell 407 based there. Some of this info, may be out dated or incorrect. Although you may want to contact these companies if you want more accurate information. AGO
