This document is a Justification Review Document for a sole source determination for the overhaul of Heat Exchangers for the National Guard Bureau. It outlines the authority cited (41 U.S.C. 1901 as implemented in FAR 13.106-1(b)(1)) for soliciting from a single source.

This document explains why the government is pursuing a sole source contract for Heat Exchanger Overhaul services. It details that the service was originally part of a contract with Limco Airepair, Inc., who discovered more extensive damage than initially anticipated. Limco is stated to be the only reasonable source due to their possession of the part, necessary tools, expertise, and the critical, time-sensitive nature of the requirement. Re-competing the requirement would incur additional costs and delays. The document also mentions that ACC has approved three vendors for this service to help alleviate a backlog, and Limco was the lowest cost and fastest option among them. This information is relevant to potential bidders as it explains the rationale behind a sole source award and the specific circumstances that led to this determination.
