The Government will not pay for any information, costs, or responses submitted in response to this notice. No solicitation is available at this time, and the Government does not intend to award a contract based solely on responses to this announcement.

The Government may contact respondents to obtain additional information regarding their capabilities.

2. Requirement Description

The Department of the Air Force is conducting market research to identify capable sources for a potential follow-on requirement for F138-100 engine sustainment supporting C-5M aircraft mission requirements.

The current F138-100 Engine Sustainment contract is an indefinite delivery, indefinite-quantity service contract. The current contract was competitively awarded to Canadian Commercial Corporation.

The anticipated requirement may include material management, engine maintenance, component support, engineering, airworthiness, and related sustainment services. The Government has not determined the acquisition strategy, contract type, period of performance, competition approach, or socioeconomic set-aside approach for any future requirement.

3. Anticipated Scope

Interested parties should demonstrate their capability to perform some or all of the following functions:

  1. Provide material-management functions, engine maintenance, and subcontractor component-support services.
  2. Provide supply liaison support and depot-level maintenance and repair capability, including required equipment and tooling.
  3. Develop and update maintenance build plans using Reliability Centered Maintenance Plus principles.
  4. Comply with applicable Technical Order data and Time Compliance Technical Orders, including new or revised technical requirements.
  5. Support engineering investigations.
  6. Support Product Quality Deficiency Reports.
  7. Provide analytical condition inspections.
  8. Manage and use Government-furnished property, including Government-owned parts and equipment, as authorized and made available by the Government.
  9. Support and maintain certifications and compliance associated with airworthiness requirements.
  10. Integrate and coordinate peculiar support equipment.

b. Technical Capability

  • A description of the company’s capability to meet each anticipated scope area identified in Section 3.
  • Identification of any scope areas the company cannot perform.
  • Description of facilities, equipment, tooling, technical data access, quality systems, certifications, and workforce qualifications relevant to F138-100 or comparable military/commercial aircraft engine sustainment.
  • Description of experience supporting airworthiness, technical-order compliance, engineering investigations, product quality deficiency reporting, and analytical condition inspections.

c. Relevant Experience
For each relevant effort performed within the past five years, provide:

  • Customer name and contract number, if releasable;
  • Period of performance;
  • Brief description of work performed;
  • Relevance to the anticipated requirement;
  • Contract value or value range, if releasable;

d. Teaming and Subcontracting
Respondents proposing to use teaming arrangements or subcontractors should identify:

  • Relevant prior teaming experience; and

e. Small-Business Participation
All respondents are requested to provide a reasonable estimate of anticipated small-business utilization as a percentage of total contract value, with supporting rationale. Identify the anticipated supplies or services suitable for small-business participation and the socioeconomic categories expected to be utilized.

If a small business intends to compete as a prime contractor under a potential small-business set-aside, it should describe its planned approach to complying with applicable limitations on subcontracting, including:

  • The anticipated percentage of contract performance to be performed by the prime contractor and similarly situated entities;
  • The anticipated percentage of payments to be made to subcontractors that are not similarly situated entities;
  • The anticipated division of work among teaming partners and subcontractors; and
  • The basis for concluding that the proposed performance approach is achievable.

Other than small businesses should also describe their anticipated approach to small-business subcontracting and their experience meeting small-business subcontracting commitments on comparable efforts.

5. Acquisition Strategy

The Government has not determined an acquisition strategy for this potential requirement. Information received in response to this notice will be used to assess the availability and capability of industry sources and to inform potential competition and small-business participation strategies.

The Government may consider full and open competition, a socioeconomic set-aside, or another acquisition approach, as appropriate. Nothing in this notice constitutes a commitment by the Government regarding any future acquisition strategy.
