Pricing and Operation Explained

Initial Contact

SDA will issue an RMA (Return Material Authorization) to the customer which should be filled out and sent back to SDA with the unit.



The customer is expected to cover all shipping costs associated with repairs, rebuilds or return without repair.


Analysis Period

SDA requires 4 weeks to analyze (inspect) and then repair the unit from the time it arrives at our facility. 


Analysis Fee

SDA charges $2,000 US to analyze the unit, make a preliminary determination of everything wrong, and then provide a tear down report and quote for repair, overhaul, recertification, or other costs associated with the RMA. This must be paid up front.

Analysis Fee and Repair/Rebuild Conditions

The $2,000 analysis fee applies to the repair/rebuild cost if the customer proceeds with a repair/rebuild. If a repair/rebuild is not performed, SDA will ship the unit back to customer in the state it was received.

The cost of repair/rebuild is broken down into one of 3 categories based on the tear down report as described below. Contact SDA for current pricing concerning these categories:
