A TSO (Technical Standard Order) is a minimum performance standard for specified materials, parts, and appliances used on civil aircraft. When a manufacturer is authorized to produce a material, part, or appliance to a TSO standard, it is referred to as TSO authorization. For TSO parts like TSO-C11E, TSO-C39C, TSO-C90B, TSO-C50C, TSO-C127A, Purchasing Union is here to help. Owned and operated by ASAP Semiconductor, we have access to an inventory of more than two billion new and obsolete parts for the aerospace, civil aviation, and defense industries, all available with short lead times and competitive prices. For parts not in our inventory, our team of dedicated account managers can efficiently track them down though our extensive international supply chain network that spans United States. To begin the purchasing process immediately, submit an RFQ below. Sales representatives are standing by and will respond to your inquiries in 15 minutes or less, 24/7/365.
