Maintenance

Home » Maintenance

Please see our Commercial and Military pages to see how we can provide timely, high-quality repairs to your aircraft or components.

Columbia Helicopters is in the rare position of holding both Type Certificates and Production Certificates for our Columbia Model 234 Chinook and Columbia 107-II helicopters.

These certificates provide the company with the engineering and manufacturing details for both airframes, and enable our employees to work directly with the FAA on improvements and modifications of these helicopters.

Consequently, the depth of our knowledge base, coupled with our highly experienced maintenance personnel, allows us to offer an unprecedented level of service and support for customers with similar aircraft and/or components and systems.
