About this archived opportunity

The Government is conducting Market Research for this Request for Information (RFI) to identify potential sources that may possess the expertise, capabilities, and experience to meet the requirements for design, qualification and production and repair of the Vibration Analyzer, PBS-4100+ NSN: 6635-01-630-9391 and various accessories kits. The purpose of the Portable Balancing System (PBS)-4100+ is used to perform trim balance and vibration diagnostics on many types of gas turbine engines and other rotating machinery. This equipment offers added features and enhanced functionality to simplify the job of engine mechanics and flight line personnel. Small, lightweight, fast working and ruggedly built, incorporates the latest configuration of electronics to maximize performance and maintainability. The PBS-4100+ is capable of automatically collecting and recording the vibration data, calculating precise balance solution and determining the specific balance weights required (all in one shot after one engine run). The PBS-4100+ also allows the user to select the engine type from an onscreen menu and recall data files for that engine type. This will be a 5-year contract (a 12-month basic year and 4 one-year ordering periods). Electronic procedures will be used for this RFI. Interested parties may identify their interest and capability by submitting a Statement of Capabilities to Contracting Officer and Program Manager. Repairs shall be completed 30 days after receipt of asset. The Original Equipment Manufacturer (OEM) is Mechanical Technology Instruments, CAGE Code: 26741. Mechanical Technology Instruments is the sole owner of the technical data needed. The Government does not own any of the data needed to perform the production and repair of this item. A determination by the Government about whether or not to compete the contract will be based on an assessment of responses to this notice that is solely within the discretion of the Government. Information received will be considered solely for the purpose of determining whether or not to conduct a competitive procurement. The Government has determined that this system is a commercial item.
