About the Bell Helicopter 427

The Bell 427 is a light twin-engine helicopter that entered service in 2000, designed for corporate transport, emergency medical services, and law enforcement roles. Built by Bell Helicopter (now Bell Textron), the 427 features a four-bladed soft-in-plane main rotor system derived from the Bell 430, paired with a sleek fuselage optimized for speed and passenger comfort. Its twin Pratt & Whitney Canada PW207D1 turboshaft engines provide excellent single-engine performance and hot-and-high capability, making it popular in mountainous regions and demanding operating environments.

The spacious cabin accommodates up to seven passengers in executive configurations or can be rapidly reconfigured for medevac missions with stretcher installations. With a maximum cruise speed of 140 knots and a range exceeding 350 nautical miles, the 427 competes directly with the Eurocopter EC135 and Agusta A109 in the light twin market. Its glass cockpit, low vibration levels, and relatively quiet operation have made it a favorite among corporate operators seeking a balance between performance and comfort.

While production numbers remained modest compared to some competitors, the 427 carved out a loyal following in North America and select international markets. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
