Capability domains
Eight domains, two shops.
Each domain lists the shops that hold the capability — so an inquiry reaches the right station first time.
Hydraulics
Flight control, landing gear and utility hydraulics, tested on instrumented closed-loop rigs.
Actuators, manifolds, valve blocks, hydraulic pumps, power control units, steering and nose gear actuators.
- Atlas
- EMC
Electromechanical
Motor-driven and sensor-driven assemblies where mechanical wear and electrical fault both have to be found.
Linear and rotary actuators, outflow valves, power packs, starters, fans and sensors.
- Atlas
- EMC
Power generation
Aircraft electrical power components, supported by load-bank test capability.
IDGs, CSDs, generators, APU generators, GCUs, voltage regulators, starter generators.
- EMC
Fuel systems
Fuel delivery and control components repaired to OEM and engineered standards.
Fuel tank boost pumps, pumping unit assemblies, surge control valves, control units.

Engineered repairs & DER
Repairs developed where no manual procedure exists — recovering parts that would otherwise be scrapped.
Out-of-manual repair development that reduces cost and turnaround versus replacement.
- Platform-wide
Specialty processes & fabrication
The in-house processes that make engineered repair development possible.
Precision machining, non-destructive testing and approved parts fabrication.
- Atlas
Material solutions
Parts availability that keeps a repair moving when a component is beyond recovery.
USM sourcing, exchange support and parts availability that keep repairs moving.
