Billings Flying Service can overhaul or repair return to service all of your CH-47 driveshafts and adapters. We can re-balance flex packs, repair sealing surfaces, and bring your driveshafting back into spec. We have the tooling, test equipment and spare parts to keep your driveshafting components airworthy. For more information on CH-47 driveshafting please read our guide on chinook helicopter parts.
