Inventory Sales. Turbine Engine Solutions stocks a large inventory of material or replacement parts in new, serviceable and overhauled condition for JT8D, PT6A and CFM56 models. We service and will almost certainly guarantee to have the part you require in stock. Turbine Engine Solutions also carries repairable or as removed inventory from engines we have disassembled or taken in as trade, this will ensure that parts you require will be in stock. These parts are inspected, made serviceable, tagged and ready for your immediate needs. All material and replacement parts are fully traceable to either major airline carriers or small private operators. Material is inspected and tagged at our facility or one of our FAA approved vendors, and audited to ensure a high quality standard is always maintained.
