Sterling Helicopter is a helicopter maintenance, engineering and parts company. It has been in business since 1984 and says it has 40 years of experience. It is an authorized dealer and service provider for several helicopter brands. Its technicians are FAA certified and factory trained, and it offers 24/7 AOG support.

Sterling handles maintenance and repairs, including upgrades, new installations, retrofits and modifications. The company repairs Airbus, Sikorsky, Agusta, MD and Bell helicopters. Each repair is carried out by FAA certified technicians who complete thorough training before any maintenance.

The company overhauls helicopter components for civil, military and government aircraft. Its factory trained technicians clean, disassemble and carry out non-destructive testing of dynamic components. The avionics team handles troubleshooting, repair, testing and installation of helicopter parts. Work ranges from scheduled inspections to full cockpit upgrades.

Sterling offers FAA certification services for helicopters and airplanes. This covers Part 23, 25, 27 and 29 aircraft. Services include turn-key STCs, DER and DAR services, project management and FAA communication. The company also supports STC owners with life cycle services, such as sales tracking and STC amendments. It handles foreign validations for EASA, ANAC and TCCA.

Sterling designs and makes structural mounting provisions for rotor and fixed wing aircraft. Mounts can carry LiDAR, camera, sensor and special mission equipment. Isolation systems protect the mission equipment from aircraft vibration. The company holds FAA PMA approval, so it can make parts that support an STC it has certified.

The company is a Safran Certified Maintenance Center for line and modular maintenance. It offers spare helicopter parts and tooling, rental tools, standard exchange and warranties. It also provides pre-buy surveys for buyers, along with global import and export of helicopters.
