Fast Turns To Get You Back In Service – From our shop floor to the flight line, your Honeywell APU will be returned to service quickly. To reduce engine downtime, we have optimized the process flows throughout our facilities for maximum efficiency.

Additionally, we focus on developing repair processes to restore your components to OEM specifications, reducing the need for expensive new replacement parts. While your APU is in our shop, one of our dedicated staff will keep you informed about its progress so you can make quick, confident maintenance decisions.

Comprehensive LRU services – StandardAero offers world-class repair and overhaul services across multiple types of LRUs and best-in-class operational performance. Our dedicated LRU repair teams are strategically located in the U.S., Canada, Europe, and Asia-Pacific, providing 95% on-time delivery, low turnaround times, and exceptional quality for our customers worldwide. We blend state-of-the-art technologies with our extensive engine knowledge to provide comprehensive LRU services, including R&O, program management, exchange and forward exchange, sampling, reliability engineering. And AOG support for P&WC PT6 and PW100 engine LRUs and Honeywell / P&WC APU air, fuel, oil, and electrical LRUs.

Dedicated Field Service Teams available 24/7 – Unlike most MRO providers, StandardAero doesn’t pull technicians from the shop floor to assist your AOG event. We have dedicated Field Service Teams who are trained, equipped, and authorized to provide troubleshooting, emergency warranty, and maintenance services 24-hours a day, anywhere in the world. If you can’t come to us, we will come to you!
