The Bell 429 is similar in structure to the Bell 427 with a composite tailboom and advanced tail rotor drive shaft. The new main and tail rotor blades are designed with lower tip speed and swept tip to reduce noise levels. Safety features include a reinforced cabin that can withstand rollover.

The basic helicopter is fitted with two sliding cabin doors. In addition to the sliding doors, the emergency medical services (EMS) variant can be configured with optional clamshell doors to allow ease of access with a roll-on / roll-off stretcher-loading system operated by a single person.

In February 2006, Bell Helicopter selected Honeywell to provide five elements of the avionic suite for the Bell 429. The dual-channel KSG-7200 air data attitude heading reference system (ADAHRS), which uses Honeywell’s solid-state micro-electromechanical sensors (MEMS) technology instead of spinning mass gyros and accelerometers, will be standard equipment.
