Dedicated People. Inspired Solutions.

Over the past 50 years, Columbia Helicopters has built a reputation for itself – reliable, skilled, experienced, and customer focused.

What Can Columbia Do for You?

Trusted worldwide, commercial and government heavy-lift helicopter operators choose Columbia for a comprehensive range of responsive life-cycle support and MRO services, from tip to tail, in the hangar or in the field.

Columbia Helicopters holds a Type and Production Certificate for the Columbia Model 234 Chinook and the Columbia Model 107-II Vertol and Type Certificate for the Columbia CH-47D Chinook. Columbia is a factory-authorized service center for Honeywell, the Total Logistics Support Center for the GE T58/CT58 engines, and a NAVAIR-approved MRO facility.

There is a difference between knowing how to maintain a helicopter and understanding what’s required to keep it operating in peak condition. We understand — because we don’t just support them — we fly them, too.
