About the Bell 412

The Bell 412 is a twin-engine medium utility helicopter that has become one of the most versatile rotorcraft in civil and government service since its introduction in 1981. Developed from the ubiquitous Bell 212, the 412 replaced the two-blade rotor system with a four-blade composite main rotor that dramatically reduced vibration and improved performance, making it particularly well-suited for demanding missions where crew endurance and passenger comfort matter. Bell delivered over 1,200 units across multiple variants, with the type finding favor among air ambulance operators, police departments, offshore oil support fleets, and utility operators worldwide.

The 412's twin Pratt & Whitney PT6T turboshaft engines provide exceptional single-engine safety margins and hot-and-high performance, while its spacious cabin can accommodate up to 14 passengers or be rapidly reconfigured for medical evacuation, cargo, or search-and-rescue roles. The type's reliability and relatively low operating costs have made it a mainstay for municipal fire departments and emergency medical services across North America, where its 140-knot cruise speed and three-hour endurance provide rapid response capability over urban and wilderness terrain alike. Later variants like the 412EP and 412EPI introduced advanced avionics and more powerful engines, extending the type's operational relevance well into the 21st century.

SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
