ℹ️ ➖➖➖ The Bell 412 is a utility helicopter of the Huey family manufactured by Bell Helicopter. It is a development of the Bell 212, with the major difference being the composite four-blade main rotor. Development began in the late 1970s with two Bell 212s being converted into 412 prototypes. An advanced four-blade main rotor with a smaller diameter replaced the 212's two-blade rotor. A Bell 412 prototype first flew in August 1979. The initial model was certified in January 1981 with deliveries commencing in the same month. The 412 model was followed by the 412SP (Special Performance) version featuring larger fuel capacity, higher takeoff weight and optional seating arrangements. In 1991, the 412HP (High Performance) variant with improved transmission replaced the SP version in production. The current production version, 412EP (Enhanced Performance), is equipped with a dual digital automatic flight control system. In 2013 Bell introduced the 412EPI which includes an electronic (Digital) engine control for a PT6T-9 engine upgrade, and a glass cockpit display system similar to the Bell model 429. Also featured is a Garmin touchscreen navigation system, and the BLR Strake and Fast Fin upgrades for improved hover performance. Over 700 Model 412s (including 260 by AgustaWestland) have been built.
This is the “next generation” Bell 412SP (Special Performance), with its Pratt and Whitney Canada PT6T-3BF engines, reliably performs in the most extreme climates on the planet every day. From its research and experience of its older predecessor, the Bell 212, this Special Performance version of the Bell 412 features larger fuel capacity and higher takeoff weight than the standard model. Each of our Bell 412 helicopters come with a BLR Fastfin. Bell 412EPi is latest variant of the Bell 412 helicopter and an upgrade of the 412EP (Enhanced Performance). The helicopter is equipped with an electronic (Digital) engine control for a PT6T-9 engine upgrade and a glass cockpit display system similar to the Bell 429.
Its expansive cabin can be configured to accommodate either cargo or personnel. Its wide opening 7.7 foot doors accommodate forklift loading into a 220 cubic foot cabin.
📑 ➖➖➖ The Guyana government has already purchased a heavy-lift Bell 412-EPi helicopter for which monies were Monday approved and the aircraft is due to arrive here the latest by next year February, well-placed sources confirmed. The aircraft costs US$13.5 million but Guyana got a deal that includes pilot training, engineer training, product support and three-year warranty for US$9.5 million. “This aircraft is going to be a major part of our emergency assistance and security environment,” the source said.
