Aircraft Engines, APU & Propulsion (MRO) installations at Hamad International Airport (DOH)

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.

Hamad International is what happens when a state airline designs its own cathedral. Opened in 2014 and already expanded twice, it serves as Qatar Airways' global spine and routinely tops Skytrax's best-airport rankings. 2024 traffic hit 52.7 million passengers and cargo cleared 2.6 million tonnes — both records. Phase C, now in tender, will lift capacity beyond 70 mppa and add a second passenger processing hall.
