Sales Order Terms and Conditions


Upon request, MDC AIRCRAFT SERVICE will acknowledge receipt of hard copy purchase orders, and their acceptance or denial.


Unless other terms have been agreed to, all manual orders will have a $50 Minimum Order Value, and no line minimum. 


An item noted as “Special Order” on a quote is subject to a cancellation fee of up to 100% of the quoted price. Orders for Stock-class parts may be subject to a cancellation fee.


Due to current volatility within the global supply chain, prices and lead times for parts not in-stock are subject to change without notice. MDC AIRCRAFT SERVICE may request an adjustment to quoted and acknowledged pricing and/or lead times.

Parts shown without prices are subject to MDC AIRCRAFT SERVICE Standard Terms and Conditions for Quotes.


Shipments to customers who have not established credit terms will be made on a C.O.D., Credit Card or ACH payment basis.

To establish open terms with MDC AIRCRAFT SERVICE, a customer must provide six trade references.

MDC AIRCRAFT SERVICE reserves the right to modify or cancel credit terms and/or credit limits at any time without notice, and require guaranteed security or payment in advance for the amount of the order.


MDC/MERCURY will deliver a customer’s shipment with a MDC/MERCURY certificate of conformance. This document certifies that the parts have been produced under Federal Aviation Administration approved manufacturing and quality control systems/methods and are new and in airworthy condition. FAA 8130-3 is provided upon request for an aditional fee.

All other product will be delivered with a MDC/MERCURY certificate of conformance. If a third party holds the FAA approval, a customer may request a copy of the manufacturer certificate of conformance and/or an FAA Form 8130-3 or ATA106.

For standard parts and raw material, a copy of the manufacturer certificate of conformance and/or a test report (a charge may be required) will be provided upon request.
