If you limit your list to Pratt & Whitney of Canada PT6A engines, it is still a long list.
I have skydived from: Westwind Beechcraft 18, Beechcraft King Air, DHC-6 Twin Otter, Pilatus Porter, Quest Kodiak, etc.
Since the PT6A is the most popular engine in its class, the entire list is much longer: Beechcraft 99 and 1900 commuters, Bell Twin Huey helicopter, Cessna 208 Caravan and 408 Skycourier, DHC-2 Turbo-Beaver, DHC-Otter conversion. DHC-4 Cariboo conversion, DHC-7, Embraer Bandierante and some Tucanos, most Pilatus airplanes. Piper Cheyenne, Quest Kodiak, Saunders S-21 conversion, Shorts Sherpa,TBM, Thrush Commander crop-duster, etc.
