CH-47 MRO

Airframe

Billings Flying Service has the facilities, tooling, and staff to perform maintenance, modifications, and refurbishment on the entire CH-47 airframe. We have built a robust CH-47 maintenance program that leverages decades of experience refurbishing a wide range of rotorcraft including Hueys, Pumas, Sea Kings, and Blackhawks.  We continue to maintain our own fleet of CH-47D Chinooks and can help you do the same.
