In 2004, Bell offered a redesigned 427 version, the "Bell 427i", which was developed in partnership with South Korea's Korea Aerospace Industries and Japan's Mitsui Bussan Aerospace. The agreement gave KAI the development and production responsibility for the fuselage, cabin wiring, and fuel system. Mitsui Bussan became a financial backer. The 427"i" included a newer glass cockpit and navigation systems to allow single pilot flying under Instrument flight rules. The design had a fuselage lengthened 1 ft 2 in (0.36 m), a more powerful engine version and transmission, and increased takeoff weight. However, the program was canceled and focus shifted to the improved Bell 429. In February 2005, the existing 80 orders for the 427"i" were converted to the 429. On January 24, 2008, Bell announced plans to officially discontinue its 427 line after current order commitments were fulfilled in 2010.
