For Rolls Royce MK511-8 SPEY Engine Servicing & Exchange

(80AFRC25PA04)

1. Federal Acquisition Regulation (FAR) 6.303-2(b)(1) – Identification of the agency and the contracting activity, and specific identification of the document as a “Justification for other than full and open competition.”

This document is a justification for other than full and open competition prepared by National Aeronautics and Space Administration (NASA) Armstrong Flight Research Center

(AFRC).

The procuring agency is the NASA, and the contracting activity is AFRC.

2. FAR 6.303-2(b)(2) – The nature and/or description of the action being approved:

This justification provides the rationale for contracting by other than full and open competition to award a sole-source contract to for Rolls Royce MK511-8 SPEY Engine Servicing & Exchange.

3. FAR 6.303-2(b)(3) – A description of the supplies or services required, to meet the Agency’s needs (including the estimated value):

In accordance with FAR 6.303-2(b)(3), the required services support the overhaul, inspection, shipment, and installation of aircraft engines in support of NASA’s operational needs. This includes maintenance and repair of two engines, shipment logistics between multiple NASA centers and the contractor facility, engine removal and installation on the NASA 808 aircraft, and verification of proper engine function. The total estimated value of this requirement is , with a period of performance of 18 months from the date of award.

The operation includes the shipment of engine serial number 11176 from NASA Langley Research Center (LaRC) to the contractor’s facility to undergo a 1C service, specifically a corrosion inspection as outlined in Rolls-Royce Service Bulletin 72-666, Appendix 1C. Upon completion of the service, the engine will be returned to NASA LaRC.

In addition, engine serial number 8801 will be shipped from NASA Armstrong Flight Research Center (AFRC) to the contractor’s facility for a midlife inspection and necessary repairs, after which it will also be returned to NASA LaRC.

The contractor will then be responsible for removing and safely storing engine serial numbers 11021 and 11022 from the NASA 808 aircraft, installing the serviced engines

(11176 and 8801), and conducting operational checks to verify proper engine performance prior to return to service.

All records and test results necessary to document the completed services will be provided by the contractor.

4. FAR 6.303-2(b)(4) – An identification of the statutory authority permitting other than full and open competition:

The statutory authority permitting other than full and open competition is 10 U.S.C.3204(a)(1), as implemented by FAR 6.302-1 Only one responsible source and no other supplies or services will satisfy agency requirements.

5. FAR 6.303-2(b)(5) – A demonstration that the proposed contractor’s unique qualifications or the nature of the acquisition requires use of the authority cited:

The rationale supporting the use of 10 U.S.C. 3204(a)(1) is that only one responsible source is capable of providing the required services due to the unique qualifications of the proposed contractor, as described below.

The Rolls-Royce MK511-8 engines are considered heritage systems, with only a limited number of vendors—domestic and international—capable of supporting their repair and overhaul. Due to the age, complexity, and specialized nature of these engines, only vendors with access to qualified spare parts, experienced personnel, and highly specific technical expertise can meet the maintenance requirements.

is the only remaining U.S.-based company certified to provide full maintenance support for the Rolls-Royce MK511-8 GIII engines. Rolls-Royce no longer performs direct maintenance on these engines and now offers only limited technical support, typically coordinated through . As the MK511-8 continues to age, its sustainment has become increasingly uneconomical, leading most providers to exit the market. Notably, even has announced its intention to discontinue support for the MK511-8 by next year.

Given the multi-month lead time required for the level of service needed, any delay in procurement would jeopardize the mission schedule for NASA 808, which is scheduled to undergo an engine change in April 2026.

6. FAR 6.303-2(b)(6) – A description of the efforts made to ensure that offers are solicited from as many potential sources as practicable, including whether a notice was or will be publicized as required by Subpart 5.2 and, if not, which exception under 5.202 applies:

A notice to the Government Point of Entry (GPE) website (Sam.gov) was published on June 6, 2025, in accordance with FAR Subpart 5.2. This posting informed potential sources of NASA’s intent to award this sole-source contract to

. The results of this synopsis are summarized in Section 10 below.

The Rolls Royce MK511-8 engines are a heritage product, with only a limited number of vendors—both domestic and international—capable of supporting their repair and overhaul.

Due to the age, complexity, and specialized nature of these engines, only vendors possessing qualified spare parts, experienced personnel, and unique technical expertise are capable of meeting the requirement.

Within the United States, the availability of replacement parts and certified expertise is extremely limited. As part of NASA’s market research, two companies were contacted regarding their ability to support this requirement: Only was found to have both the necessary parts and the certified technical capability.

was initially identified through an online search, which referenced a capability statement suggesting potential support for GIII 511-8 engines. However, upon direct inquiry, confirmed that they are not certified to service Rolls Royce MK511-8 engines and are in the process of closing their GIII 511-8 support department.

further advised that, to their knowledge, is the only certified vendor currently capable of performing this work.

Furthermore, Rolls-Royce has directly informed NASA Subject Matter Experts that is the only certified company authorized to perform maintenance and overhaul work on the MK511-8 engines.

Use of any source other than would introduce substantial technical and safety risks to the aircraft and project. Additionally, engaging an uncertified vendor would likely result in an ostensible subcontracting arrangement, significantly increasing both schedule delays and cost risk.

7. FAR 6.303-2(b)(7) – A determination by the contracting officer that the anticipated cost to the Government will be fair and reasonable:

This determination will be supported by price analysis conducted in accordance with FAR 13.106-3(a)(2)(ii), which allows for comparison of the proposed price with prices found reasonable on previous purchases.

The Contracting Officer will require the contractor to submit a detailed cost proposal. A formal proposal analysis will be conducted prior to award, including evaluation and negotiation (if required), to ensure the final agreed-to price is fair and reasonable. The Contracting Officer will utilize methods of price analysis that are consistent with FAR 13.106-3 and that the cost to the Government is fair and reasonable.

8. FAR 6.303-2(b)(8) – Description of the market research conducted, and the results, or a statement of the reasons market research was not conducted:

As part of NASA’s market research, were contacted.

Only was found to have the necessary parts and certified capability to support the Rolls-Royce MK511-8 engines. confirmed they are not certified and are closing their support department. Additionally, Rolls-Royce confirmed to NASA that is the only certified company authorized to perform maintenance and overhaul on these engines. A Sole Source Synopsis was posted on SAM.gov on June 3, 2025, and received zero responses, further confirming the lack of alternative sources.

9. FAR 6.303-2(b)(9) – Any other facts supporting the use of other than full and open competition:

The additional facts supporting the use of other than full and open competition include the criticality of the requirement to mission success and the urgency created by the limited remaining availability of qualified maintenance support for the Rolls-Royce MK511-8 GIII engines. The engines in question are integral to the continued operation of the NASA 808 aircraft, which is scheduled to require an engine change by April 2026.

is the only remaining U.S.-based provider with the capability, tooling, technical data access, and authorization to perform the required overhaul and midlife inspection services on these engines. Rolls-Royce no longer provides direct support for this engine model and offers only minimal technical assistance, primarily through .

Further compounding the urgency, has announced its intent to discontinue support for the MK511-8 engines next year, making this potentially the last opportunity to obtain qualified servicing. Given the extended lead times required to complete engine servicing, shipping, installation, and post-installation verification, any delay in award would jeopardize aircraft availability and mission readiness.

These factors, combined with market limitations and the contractor’s unique capabilities, further support the necessity of using other than full and open competition under 10 U.S.C.

3204(a)(1).

10. FAR 6.303-2(b)(10) – A listing of the sources, if any, that expressed an interest in writing in the acquisition:

A notice of NASA’s intent to award this sole-source action was synopsized on the GPE website (Sam.gov) per FAR Subpart 5.2 (See Section 6 above). The synopsis was posted on June 3, 2025, with a closing date on June 6, 2025. No companies responded.

11. FAR 6.303-2(b)(11) – A statement of actions, if any, the agency may take to remove or overcome any barriers to competition before any subsequent acquisition for the supplies or services required:

The Agency will continue to examine the market in the future for alternative solutions or new sources before executing any subsequent acquisitions for the same requirements.
