APU Overhaul & Exchange
Auxiliary Power Unit overhaul, repair and exchange-pool programmes for Honeywell and Pratt & Whitney APUs across narrow- and wide-body fleets.
About this category
Dedicated Auxiliary Power Unit specialists offering full overhaul, hot-section repair, on-condition maintenance and — critically for fleet uptime — APU exchange and lease pools. Covers the dominant civil APU families (Honeywell 131-9A/B, GTCP331, HGT1700; Pratt & Whitney Canada APS3200/APS5000) plus accessory and load-control overhaul. Buyers source an APU shop or exchange specifically when an on-wing APU is removed, because a serviceable replacement from a pool minimises aircraft-on-ground time. Providers hold APU-type-specific approvals and run test benches distinct from main-engine shops. Comparison points are exchange-pool depth, regional unit availability and guaranteed turn-time.
