The Bell 429 GlobalRanger is a light, twin-engine helicopter developed by Bell Helicopter and Korea Aerospace Industries, based on the Bell 427. First flight of the Bell 429 prototype took place on February 27, 2007, and the aircraft received type certification on July 1, 2009. The Bell 429 is capable of single-pilot IFR and Runway Category A operations.

The impetus for developing the Bell 429 came primarily from the emergency medical services (EMS) industry, which was looking for an updated helicopter. The Bell 427 was originally intended to address this market, but the 427's small cabin size would not adequately accommodate a patient litter, and the systems did not support instrument flight rules (IFR) certification. Bell's original concept for the 429 was a stretched model 427 (unveiled as the Bell 427s3i at the 2004 HAI helicopter show), but this still did not provide what Bell and its customer advisers were looking for.

Bell abandoned the 427 airframe and went to its MAPL (Modular Affordable Product Line) concept airframe that was still in conceptual development at the time. The 429 employs the all-new modular airframe concept and the advanced rotor blade design from the MAPL program, but maintains a derivative engine and rotor drive system from the 427. The basic model includes a glass cockpit and is certified for single pilot IFR. Bell partnered with Korea Aerospace Industries and Mitsui Bussan Aerospace of Japan in the helicopter's development.

Bell had flown most of the critical MAPL technology components using a 427 test bed aircraft by February 2006. The first completed 429 flew February 27, 2007. Certification was originally planned for late 2007, but program schedule delays, primarily caused by parts and material shortages common to all aviation manufacturers in that time period, caused the manufacturer to stretch the development timetable. In October 2007 the external configuration was set. In February 2008, Bell had three 429s in flight testing that had completed 600 flight hours. The 429 conducted its high altitude testing in Colorado and its high temperature testing in Arizona.

The helicopter received type certification from Transport Canada Civil Aviation (TCCA) on July 1, 2009, and from the Federal Aviation Administration (FAA) by July 7, 2009. EASA certification was announced at Helitech on September 24, 2009. TCCA and authorities in some other countries later approved an increased weight exemption for the aircraft. However, FAA and EASA disagreed with the weight exemption, which had allowed the 429 to operate for the Canadian Coast Guard.
