Our employees have many years of experience in aviation, helicopter operations, and aircraft parts sales. We understand the needs and requirements of our clients, and have earned a reputation for providing outstanding service. 


We maintain an inventory of over one million items! Our large inventory includes traceable aircraft parts, accessories, and engine spares. Our inventory includes over 80,000 line items, in-stock and ready to ship, for most makes and models of light and medium turbine helicopters produced in the United States and Western Europe.

Our Condition Codes

When a part arrives at our facility, we perform a visual inspection of the part and a review of the support documents, if available, to confirm the condition of a part. All parts we ship include our Certification of Conformance (C of C). Due to various condition codes used by commercial aircraft operators around the world, and the confusion condition codes sometimes cause, we use the following four condition code definitions to categorize the parts in our inventory
