Bell 412epi vs Leonardo Aw189 vs Robinson Helicopters R66 vs Sikorsky S 76d

The Bell 412EPi is a medium, twin‑engine utility helicopter commonly used for public service and offshore support; it typically carries around a dozen passengers in a transport layout and offers moderate range suited to regional missions. The Leonardo AW189 sits a class above as a super‑medium twin designed for longer overwater and offshore work; it generally carries more passengers than the 412 and is optimized for longer range and higher payload, making it the most “offshore‑oriented” option here. The Robinson R66 is a light, single‑engine helicopter aimed at private, training, and light commercial roles; passenger capacity is much smaller (roughly four plus pilot), and range is shorter, though efficient for point‑to‑point flights. The Sikorsky S‑76D is a twin‑engine intermediate helicopter focused on corporate/VIP and EMS; it typically carries 6–8 passengers in executive or utility layouts and offers strong speed and solid range, generally exceeding light helicopters and competing with the 412, while usually below the AW189’s long‑range offshore profile.
