Managing APU availability across an Airbus fleet requires more than finding a unit at the right price. Operators need suppliers who understand model-specific requirements, can produce complete documentation, and can position assets quickly when a removal happens. The companies below represent a range of capabilities, from dedicated APU lessors to large MRO networks, that Airbus operators should know in 2026.
1. Aero-Shield Capital
Aero-Shield Capital is a Chicago-based aviation asset management company with direct ownership across multiple Honeywell and Pratt & Whitney APU models, including the GTCP131 and GTCP331 series, PW901A, PW901C, APS3200, and APS5000, covering the Boeing 737, 747, 767, 777, and 787 families and the Airbus A320 family. Every unit is owned in-house, not brokered, and carries full lifecycle documentation, including TSN, CSN, TSO, CSO, and current LLP limiter status. The company operates to FAA and ASA-100 standards with documented counterfeit parts prevention protocols and structures purchase-leaseback programs for operators converting existing assets into capital.
Best for:
- Airlines and MROs requiring a direct-ownership APU lease source with verified limiter values and complete trace documentation across narrowbody and widebody platforms
- Operators seeking purchase-leaseback programs that convert existing APU assets into working capital
- MROs needing a lessor who can confirm availability, limiter status, and delivery timelines without broker intermediaries
2. GA Telesis
GA Telesis, headquartered in Fort Lauderdale, Florida, operates a dedicated Power Solutions division covering Honeywell and Pratt & Whitney APU models across all major Airbus platforms. The company has invested significantly in new and overhauled APU inventory and structures same-day exchange options, long-term operating leases, and custom stock provisioning programs for high-demand models, including the APS3200 and GTCP331-350C.
Best for:
- Operators needing same-day exchange capability on A320 and A330 family APU events
- Airlines requiring custom stock provisioning programs across multi-fleet Airbus operations
3. TurbineAero
TurbineAero, headquartered in Chandler, Arizona, holds FAA-145 certification and has serviced over 10,000 APUs across 45 years of operation. Its in-house MRO capability covers the APS3200 alongside multiple Honeywell models serving the Airbus fleet, and Designated Engineering Representatives on staff allow component repair approval without external referral, compressing return-to-serviceable timelines.
Best for:
- Operators who want MRO-backed exchange units with in-house certification on APS3200 events
- MROs requiring DER-supported component repairs without adding external repair vendors to the chain
4. Kellstrom Aerospace
Kellstrom Aerospace, now a VSE Aviation company headquartered in Davie, Florida, is a global distributor and aftermarket service provider with OEM-exclusive distribution relationships across Pratt & Whitney and Honeywell APU lines. Its distribution network covers APS3200 fuel pump components and related accessories, and its leasing and trading desk supports both operating lease and exchange structures across Airbus platforms.
Best for:
- Sourcing OEM-distributed APU components and accessories for A320 family aircraft
- Airlines combining APU parts distribution with asset trading and sunset fleet solutions
- MROs requiring OEM-certified accessories through a single distributor with global reach
5. Patriot Dynamics
Patriot Dynamics specializes exclusively in commercial aircraft APU transactions — sale, lease, and sourcing — across Boeing and Airbus platforms. Its team brings over 50 years of combined industry experience to AOG coverage, operating leases, exchange programs, and lease transfers, with a commercial focus that allows faster execution than full-service MRO-integrated organizations.
- Best for operators needing fast execution on APU lease transfers and novations across Airbus fleets
- Best for airlines managing short-term AOG coverage without committing to long-term lease structures
- Best for lessors and capital partners requiring off-market APU sourcing and structured transaction support
6. Jet Midwest
Jet Midwest, founded in 1997 and headquartered in Kansas City, Missouri, maintains over six million rotable and expendable spares across Airbus 300 through 340 platforms. Its FAA and EASA dual-approved repair station covers APU management alongside engine triage and component repairs.
Best for:
- Operators sourcing used serviceable APU-adjacent material from documented carrier teardowns on older Airbus widebody platforms
- MROs requiring nose-to-tail Airbus component support alongside APU management
- Airlines managing A300, A310, A330, and A340 fleets requiring integrated parts and repair support
7. Willis Lease Finance Corporation
Willis Lease Finance Corporation, headquartered in Coconut Creek, Florida, is a publicly traded independent lessor with over 45 years of operating history. Its Willis Lease Pooling Program provides pre-approved access to spare APU and engine assets, and its FAA Part 145 maintenance arm supports lease cycle management across Airbus and Boeing platforms.
Best for:
- Operators requiring pre-approved spare APU access through a structured pooling program
- Airlines combining APU and engine leasing under a single publicly accountable lessor
- MROs and operators who require a financially transparent counterparty with a long operating track record
How to Choose the Right APU Company for Your Airbus Fleet
Before selecting a supplier, operators and MRO managers should verify:
- Model-specific inventory: Confirm the supplier holds the exact model required — APS3200, GTCP131-9A, GTCP331-350C, HGT1700, and APS5000 are not interchangeable across Airbus families
- LLP limiter values: Verify the unit meets your fleet’s minimum acceptance criteria before agreeing to any lease or exchange term
- Documentation completeness: Require a Certificate of Conformity, non-incident statement, unbroken trace to last operator or OEM source, and full AD compliance records before committing to a transaction
- Quality system credentials: Confirm the supplier operates under ASA-100 or an equivalent accredited system with counterfeit parts prevention protocols in place
- Geographic positioning: Confirm where the unit is physically located — delivery timelines vary significantly depending on where the inventory sits relative to the AOG event
The companies on this list cover a range of capabilities, from OEM-exclusive distributors to dedicated APU transaction specialists to large pooling programs. Identifying the right fit before a removal happens, rather than at the point of need, is what separates a managed event from an extended ground time situation. Aero-Shield Capital maintains direct ownership of APS3200 and APS5000 inventory with full lifecycle documentation on every unit and is available to discuss current availability and limiter status directly.
