Maintenance

General Aviation Maintenance

Your aircraft deserves a maintenance partner you can trust

FAA-certified technicians with turbine, backcountry, and government fleet experience — keeping aircraft owners and operators flight-ready, not grounded. 

Maintenance expertise you can depend on

Neptune Aviation’s experts initially began performing maintenance on our fleet of P2V Neptune aircraft, continuing to hone their skills on the BAe 146 and, more recently, our fleet of Aero Commander 690 aircraft. 

Today, the same team of FAA-certified, factory-trained technicians provides maintenance and repair services for individual aircraft owners, business operators, charter organizations, and government fleets. They apply their practical experience to routine inspections, troubleshooting, structural repairs, and complex maintenance work.

Every aircraft receives the same focus on safety, precision, and workmanship that we bring to our own fleet. Throughout the process, we keep you informed, respond quickly, and work efficiently to return your aircraft to service.
