What is Overhaul in Aviation?
Overhaul is the process of returning an aviation component to like-new condition. Overhauled parts can last a decade or more, and they conform to the service tolerances for airworthiness established by the manufacturer or certificate holder. If you don’t need the quick turnaround of an exchange, you can save money and get a long-lasting component with an overhaul. You’ll get your own core back and you only pay for the service and any parts that are repaired or replaced.

Customer Reviews
P-51 3/4 Scale Replica Build
I am building a ¾ scale P-51 that was designed by Marcel Jurca. I designed an electro-hydraulic retraction system to use instead of the hand cranked system in the plans. I secured a new Parker Oldine pump, which was pre set at 600 psi. This was not enough pressure to raise the landing gear. I was searching for a Prestolite pump, and through a series of calls ended up talking to Bryan Cox of Cox Airparts. After much discussions, he asked me why not just send him my pump and he would reset the internal by pass to give me 1500 psi which would be enough to raise the gear. Needless to say, the pump was shipped to him the next day. To my surprise it was back in my hands in less than a week and retracted the gear just the way it should. I am very pleased to say that this was one of the best experiences I have had dealing with venders.
Great Job On This Actuator
Thanks for helping us out with the 1280514-12 actuator. We flushed the system and installed new flexible hoses. We swung the gear many times and leaked checked with no leaks noted and everything worked good. Thanks again for doing a great job on this actuator.
Appreciate Y’all
I'm the installing mechanic for the Juergen Koehn's Rockwell Commander 114A GT power pack. I am very happy with the power pack and the information Cox Airparts provided during the overhaul. They were able to figure out the power pack we had installed was the wrong part number and got the correct one built and sent to us.
Amazing Expertise
“Rick’s expertise of hydraulic systems is amazing. He thoroughly understands the systems and can explain their operation in understandable terms. He accurately diagnosed a long-term problem I have been having in the gear system based on my explanation and findings. Rick’s accurate diagnosis saved me time and money chasing symptoms. I’m super happy with his service.”
FAQs
Should I choose overhaul or exchange for my aircraft components?
Overhaul is the most economical choice, if there’s not an immediate need. For AOG (aircraft on ground) issues, choose exchange to have an in-stock part shipped out to you as soon as the next day. You’ll have 30 days to return your core to us.
How does overhaul work?
Overhaul consists of tearing down or disassembling a component, cleaning it, inspecting it, repairing or replacing parts, and then reassembling the component and testing it.
What is the turn time to overhaul a part?
Turnaround times depend on the component and what it needs. A safe estimate is 4-6 weeks, but it’s best to call us to get an accurate turn time for your power pack, actuator or other hydraulic part.
What does overhaul + parts mean?
The cost is generally quoted as overhaul + parts, which means you pay for the overhaul service plus the cost of any parts that have to be replaced or repaired.
