Overview
Billings Flying Service provides heavy-lift helicopter operations and maintenance, specializing in CH-47D Chinook aerial firefighting for wildfire suppression, construction, utilities, and government programs. Its aircraft drop water using a Chinook-based system with rapid refills, and it runs an FAA Part 145 MRO that services its fleet and other military and civilian customers. The company stands out by operating the world’s largest civilian Chinook fleet, focusing exclusively on CH-47D since 2013, and maintaining long-term government contracts, while being part of Quanta Aviation Services. Its goal is to offer dependable, mission-critical aerial support for firefighting and related civilian and government missions through its specialized fleet and in-house maintenance expertise.
