This is a restricted combined synopsis/solicitation for commercial items, seeking quotations for a firm-fixed-price purchase order anticipated to be awarded on a sole source basis to Oregon Aero Inc. Only new parts with clear traceability to the Original Equipment Manufacturer (Oregon Aero Inc.) will be accepted, and no substitute or alternate parts will be considered. All parts must be approved in accordance with FAA guidelines, with a Certificate of Conformance required, and no drawings or specifications are available. The acquisition includes options to increase quantities for three line items, with the government able to exercise these options within one year after award. Interested responsible sources with the required expertise are invited to submit offers, as the agency believes Oregon Aero is the only known source for these parts.
