Aircraft Engines, APU & Propulsion (MRO)

Aircraft Engines, APU & Propulsion covers the powerplant-specialist segment of maintenance: jet-engine and turboprop shop visits, Auxiliary Power Unit overhaul and exchange, propeller and governor repair, fuel-control and accessory overhaul, and engine-component bearing and parts repair. These providers hold engine-type-specific approvals and operate test cells and clean-room shops distinct from general airframe line/base maintenance. Buyers are airlines, lessors and MROs sourcing a powerplant event or APU exchange. The category overlaps the broader MRO listing but is a recognised buy-side specialism — buyers search for an APU shop or an engine-overhaul partner specifically. Suppliers here are also tagged onto Aircraft MRO / Line Maintenance so they remain discoverable on both pages.
