1.0 Background

The National Aeronautics & Space Administration (NASA) operates multiple Gulfstream GIII aircraft at different locations. Two of these aircraft are in need of engine servicing to prevent disruption of critical flight research and prepare both aircraft for operation into the 2030s. NASA Langley Research Center (LaRC) operates GIII aircraft NASA 520. NASA Armstrong Flight Research Center (AFRC) operates GIII aircraft NASA 808. For both of these aircraft to continue flight research for at least another five years, multiple engines will need servicing.

2.0 Objectives

The objectives are to provide services for two Rolls Royce MK511-8 aircraft engines:

• Engine serial number 11176 from NASA LaRC is to undergo a 1C inspection

• Engine serial number 8801 from NASA AFRC is to undergo midlife inspection and repair

3.0 Scope

Completion of servicing for one Rolls Royce MK511-8 aircraft engines will involve:

• Shipment of engine serial number 11176 from NASA LaRC to the contractor facility

• Completion of a 1C service on engine serial number 11176 from NASA LaRC

• Return shipment of the overhauled engine serial number 11176 to NASA LaRC

• Shipment of engine serial number 8801 from NASA AFRC to the contractor facility location

• Execution of midlife inspection and repair for engine serial number 8801 at the contractor facility

• Return shipment of the serviced engine serial number 8801 to NASA LaRC

RFP/Contract No. Rolls Royce MK511-8 SPEY Engine Servicing & Exchange

• Removal and storage of engines from the NASA 808 aircraft

• Installation of engine serial numbers 11176 & 8801 on the NASA 808 aircraft

• Verification of normal engine operation on specified aircraft

• Provision of all records and test results necessary to document the completed services

4.0 Requirements

Requirements are divided into work tasks to be performed at both NASA LaRC and AFRC locations.

The first requirement is applicable to both locations.

The contractor must be an FAA certified 14 CFR Part 145 repair station with experience servicing Rolls Royce MK511-8 engines

Task Order 1: associated with engine serial number 11176 from LaRC:

1) The contractor shall prepare for shipment and transport engine serial number 11176 from NASA LaRC to the contractor facility

2) The contractor shall complete a 1C service for engine serial number 11176

3) The contractor shall prepare for shipment and transport engine serial number 11176 to NASA

LaRC

Task Order 2: associated with engine serial number 8801 from AFRC:

1) The contractor shall perform a midlife inspection and repair service for Rolls Royce MK511- 8 engine serial number 8801

2) The serviced engine serial number 8801 shall be prepared for shipment and transported to NASA LaRC

Task Order 3: associated with aircraft NASA 808 engine replacement at NASA LaRC

1) The contractor shall remove Rolls Royce MK511-8 engine serial numbers 11021 and 11022 from aircraft NASA 808

2) Prior to all engine installations, the contractor shall complete the Chapter 5 and all pertinent and related aircraft structural inspections

3) The contractor shall install engine serial number 8801 and 11176 on aircraft NASA 808, perform rigging, functional checks, and any additional testing in accordance with relevant maintenance manuals including Gulfstream and Rolls Royce

5.0 Deliverables

The deliverable items are:

• Rolls Royce MK511-8 engine serial numbers 8801 and 11176 installed and in serviceable condition on aircraft NASA 808 at NASA LaRC

• Rolls Royce MK511-8 engine serial numbers 11021 and 11022 stored on engine stands at NASA LaRC

• All documentation associated with the completion of the CMP 713011/713046 tasks for Rolls Royce MK511-8 engine serial numbers 8801 & 11176

• All documentation updated in the Gulfstream CMP database for all services provided as listed in Section 4.0

• All completed maintenance and FAA documentation relevant to services provided as listed in Section 4.0

6.0 Government-Furnished Property, Material, Equipment, or Information (GFP, GFM, GFE, or

GFI)

NASA AFRC and LaRC will provide the following hardware and personnel for this task:

• One shipping stand for a Rolls Royce MK511-8 engine; this shipping stand will be used for transport of engine serial number 8801 to the contractor facility and is to be returned to NASA LaRC upon completion of engine servicing

• NASA AFRC will prepare engine serial number 8801 for transport and will make arrangements for delivery of the asset to the contractor facility

• Rolls Royce MK511-8 engine serial number 8801 from NASA AFRC for services specified in Section 4.0

• Rolls Royce MK511-8 engine serial number 11176 from NASA LaRC for services specified in Section 4.0

• Certified ground support equipment devices for critical lifts, including slings, connectors, harnesses, etc., and qualified operators

• The contractor or Gulfstream Aerospace Corporation may provide unique equipment for engine lifts, as required

• Gulfstream GIII aircraft NASA 808 at NASA LaRC

• Two engine stands for potential long term engine storage at NASA LaRC

7.0 Security

There are no unique security requirements for this task.

8.0 Travel

Travel to NASA LaRC by the contractor will be needed to perform tasks associated with engine removal, installation, return to normal operation, and tuning.

9.0 Special Material Requirements

All hazardous materials required for this task must be approved for use at NASA LaRC and prior to delivery of the substance to each respective location. Excess hazardous material that cannot be properly disposed must be removed from NASA property for disposal by the contractor.

10.0 Other Unique Requirements

The contract shall provide the following separate cost estimates for this task:

• An estimate for shipment of engine serial number 11176 from NASA LaRC to the contractor facility

• An estimate for a 1C service of Rolls Royce MK511-8 engine serial number 11176

• An estimate for midlife inspection and repair service of Rolls Royce MK511-8 engine serial number 8801 from NASA AFRC

• An estimate for exchanging two engines on the NASA 808 aircraft at NASA LaRC including removal of MK511-8 engine serial numbers 11021 & 11022; installation and return to service of MK511-8 engine serial numbers 8801 & 11176 as specified in the Section 4.0 requirements.

11.0 Place of Performance

Except for the specific engine services, the place of performance for these tasks will be at NASA LaRC facilities located at Langley Air Force Base, Virginia.

12.0 Period of Performance

Aircraft induction dates will be determined after award. All work is expected to be completed no later than September 30, 2026.
