Reverse Engineering and Source Development for TF33 Replacement Components

The Defense Logistics Agency (DLA) is seeking small businesses capable of manufacturing and supplying an assortment of replacement components for the TF33 turbofan engine. Given the TF33’s importance over multiple platforms, maintaining a supply chain capable of keeping the engine in operation is paramount. The TF33-103 engine variant is expected to remain in service until 2037 and therefore requires spare parts for regular maintenance, repair, or engine overhaul. DLA has reached out to Mainstream to undertake a set of components, develop technical data for manufacturing, and become approved sources for future supply of these components. During this effort, Mainstream will compile all technical data necessary to manufacture items from the provided TF33 parts list in an effort to complete SAR packages and become an approved supplier.  Technical data may be elicited from government-supplied data or from inspection and reverse engineering of sample components. We have completed a preliminary review of each item and selected 9 items from the TF33 list as primary candidates for technical data and source development.
