Solicitation Number To be advised at time of issuance
DISCLAIMER: THE GOVERNMENT DOES NOT INTEND TO AWARD A CONTRACT ON THE BASIS OF THIS
SOURCES SOUGHT NOTICE OR TO OTHERWISE PAY FOR THE INFORMATION SOLICITED.
This Sources Sought Notice is issued for information and planning purposes only and does not constitute a solicitation. The Government requires that only non-proprietary information be submitted in response to this Sources Sought Notice. The Government shall not be liable for or suffer any consequential damages for the use of any proprietary information submitted. Responses to the Sources Sought Notice will not be returned. The responses to this notice are not an offer and cannot be accepted by the Government to form a binding contract. The Government reserves the right to reject, in whole or in part, any contractor's input resulting from this Sources Sought Notice. Responders are solely responsible for all expenses associated with responding to this Sources Sought Notice.
PURPOSE: This Sources Sought Notice is issued as a means of conducting market research to determine if other companies, besides CFM International (CFMI), are capable of performing all necessary tasks required to identify updated Life Discipline Manual (LDM) Confidence Factors and Life Limits for the CFM56-7B27AE of the USN P-8A fleet based on historical flight data.
The proposed contract action is for PBL support for which the Government intends to solicit and negotiate with only one source under authority of FAR 6.302-1. The effort is anticipated to be supported under the existing F108 PBL contract SPE4AX25D9406. Interested parties may identify their interest and capability to support the objectives by responding to this notice. All responses received by the notice response date will be considered by the Government. A decision by the Government not to compete this proposed contract based upon responses to this notice is solely within the discretion of the Government. Information received in response to this notice will normally be considered solely for the purpose of determining whether to conduct a competitive procurement. This notice is for information and planning purposes only and does not constitute a solicitation or commitment by the Government.
The applicable North American Industry Classification System (NAICS) code assigned to this procurement is 336413.
OBJECTIVES: The contractor would need to perform all necessary analysis to support the USN to identify updated Life Discipline Manual (LDM) Confidence Factors and Life Limits for the CFM56-7B27AE of the USN P-8A fleet based on historical flight data.
Work Planning
The Contractor shall provide support and documentation, including a statement of work (SOW), rough order of magnitude (ROM) cost, and plan of action and milestones (POAM) for performance of the life assessment work as outlined in this document, for all Chapter 5 life-limited components and critical rotating parts with recommended removal schedules applicable to USN CFM56-7B27A/3 and –7B27AE engines (Appendix B). Additionally, the Contractor shall identify future efforts, such as piece part inspection, that would validate lifing analyses and improve the confidence factors within the LDM Confidence Table.
Life Management Process Review
The Contractor shall provide USN personnel a fundamental review of the life assessment process for the P-8A CFM56-7B27A/3 and -7B27AE engine at the initiation and conclusion of this effort. The reviews shall include fundamental assumptions in the life assessment process and address the effects of damage mechanisms contributing to these assessments, including fatigue, wear, corrosion, and any other mechanisms considered, if applicable. The reviews shall also identify individual life assessment requirements or caveats for individual components and/or critical features. These reviews shall be performed via in-person and/or teleconference virtual meeting(s), and all supporting slides, visual aids, charts, and other media used to facilitate this discussion shall be provided to USN personnel.
Mission Mix Assessment
The Contractor shall conduct and report a mission mix assessment on the operational conditions of the identified components (Appendix B) for A/3 and AE engine configurations based on flight data, pilot surveys, and other historical data and present the findings of that assessment with USN. USN shall provide flight data to the Contractor for the purposes of mission mix assessment, including subpopulations of flight data that may correspond to specific configurations or operations (e.g., air-to-air refueling, engine version, location). The Contractor shall define major/minor cycle definitions and partial cycle factors as well as identify the parameters and calculation methods used to determine engine cycle counts. These cycle counts shall be calculable using decoded flight data available on the ground health monitoring system (GHMS) and used to determine engine cyclic damage content (GHMS processes full-flight downloads from the engine flight data recorder). A mission mix assessment report shall include major and minor cycle definitions and cycle type gates, mission profile characteristics, take-off ambient temperature mix, pre-flight ground idle distributions, and variability of fleet operations (e.g. variation across engines, locations, and seasons).
Life Assessment (Appendix B Components Excluding Fan Blades)
The Contractor shall conduct a life limit assessment inclusive of but not limited to the components listed in Appendix B, excluding fan blades, and as applicable to the AE engine configuration in accordance with the commercial engine LDM and best practices. Key conditions of interest for analysis include steady-state and transient conditions (such as cruise and takeoff) and engine health state at the timestep of the min and max strain (and/or stress). At a minimum, the following analyses shall be performed:
-
- Thermomechanical Analysis
The Contractor shall perform static and transient heat transfer and stress analysis for each component, each contractor-identified critical location, and each mission type as determined from the operational condition of the components.
- Material Analysis, Fatigue, and Risk
The Contractor shall conduct analysis inclusive of material properties applicable to each component and contractor-identified critical location across each mission category, including low cycle fatigue (LCF), high cycle fatigue (HCF), and/or other applicable life limiting fatigue modes. Fatigue analysis should consider multiple R-ratios and cyclic load configurations based on the thermal and stress analyses.
- LDM Confidence Factors
The Contractor shall report LDM Confidence Tables based on historical flight data and cycle accumulation, physical component testing and inspections, modeling and simulation, and/or other methods as applicable. This LDM Confidence Table shall include, but is not limited to, all components listed in Appendix B across each mission category and critical location.
-
- Life Limits and Inspection Schedule
The Contractor shall report the Operational Life, Recommended Life Limits, and Inspection Schedule inclusive of but not limited to all components listed in Appendix B as applicable to the AE engine configuration across each mission category and critical location. The Contractor shall evaluate the applicability of inspection intervals and/or service bulletin removal and replace limits on the HPT blades. Upon USN concurrence, the Contractor shall publish Chapter 5 updates and if applicable, Service Bulletin(s) in support of updated component-level life limits, removal schedules, and inspection schedules.
Life and Inspection Assessment for Fan Blades
The Contractor shall report the Recommended Inspection Threshold and Interval Schedule inclusive of, but not limited to, fan blades as identified in Appendix B and as applicable to the AE engine configuration and provide an assessment summary, inclusive of assessment assumptions, analyses results, and Confidence Factors, as applicable.
Over-the-Shoulder Technical Review
The Contractor shall provide USN engineers with the opportunity to review the technical documentation as determined to be shareable by CFM engineering that supports the deliverables and requirements of Section (4). USN may not direct further analysis or work under this SOW based upon the over-the-shoulder review.
