The U. S. Coast Guard (USCG) Medium Range Surveillance (MRS) Aircraft Program (CG-9312) is in need of an HC-144B Maintenance Training Unit (MTU).  The MTU will support the operational fleet by providing the skills, knowledge and practical experience required to maintain and troubleshoot the Avionics, Electrical, Airframe and Engine/Powerplant systems and associated equipment installed on the HC-144B aircraft.  The MTU will provide Avionics Electrical Technician (AET) and Aviation Maintenance Technician (AMT) Class “A” and Class “C” School students the ability to receive initial and advanced, hands-on, maintenance training instruction in a realistic setting that is reflective of USCG technical manuals allowing students to learn basic and sophisticated techniques of aircraft troubleshooting and repair.  The MTU device shall be capable of meeting the Enabling Learning Objectives (ELO), critical tasks, and USCG identified faults associated with the AET and AMT “A” and “C” School training requirements.  The Contractor shall  convert an existing CN-235-100 hull into an integrated HC-144B MTU with a combination of hands-on, real aircraft hardware and components as well as virtual/simulated components.  All virtual/simulated systems shall accurately reflect the real/actual system, and the systems shall to respond correctly to inputs from switches, circuit breakers, power levers, condition levers and fire handles.

The USCG does NOT require  a MTU that is completely wired with fully functional systems; the MTU only requires certain structural ‘designated areas’ to be visually and physically accurate to the real/actual components, parts and systems.  The areas that are not specifically identified as a ‘designated area’ per the critical tasks/Maintenance Procedure Cards (MPCs) are not required to meet traditional design/wiring and system functionality requirements of the HC-144B aircraft.  An ideal solution would provide both tactile components including but not limited to throttles, flaps, yokes, rudder, elevator, ailerons, and trim controls that are integrated into the Fault Isolation System (FIS) and interact with simulated and/or virtual replicas of cockpit, avionics, and other components/systems.  Students must have the ability to safely navigate throughout the physical aircraft as well as the virtual environment, including walking around the aircraft to locate specific panels and components (either real, simulated, or virtual) and to perform required maintenance steps.  Students will open actual panels, disconnect real and/or simulated, and/or virtual cables, observe component operation (either real, simulated, or virtual) in both normal and faulted conditions, and perform troubleshooting and removal/replacement actions. Virtual and/or simulated test equipment required to perform maintenance actions must be available for student operation with test equipment measurements accurately reflecting the state of the simulated aircraft system.

MTU associated terms:

  • The term “real” describes actual, physically existing hardware components and parts.
  • The term “simulated” describes components and parts that are not real and are replicas of the actual physical components.  Simulated components will be the same size and shape of the real component and part and will be within 10% of actual component weight for Remove & Install (R&I) fidelity.
  • The term “virtual” describes systems with components and parts that do not physically exist but are made by software to appear like the physical components and parts.


The purpose of this RFI is to ascertain industry’s ability to provide various MTU solutions for consideration.  Other than the GFE provided for the installation requirements, the USCG does not require a certain percentage of the MTU systems to be real, simulated, or virtual, so vendors are encouraged to provide MTU solutions that have different combinations of real/simulated hardware, software, and virtual capabilities and associated costs.

MTU Required Systems:

The MTU shall provide the student with the ability to inspect and troubleshoot (operational and functional checks and tests IAW applicable MPC) the following systems:

  1. Air Conditioning
  2. Pressurization
  3. Rain and Ice Protection
  4. Powerplant
  5. Fire Protection System
  6. Hydraulic System
  7. Fuel System
  8. Electrical System
  9. Flight Control System
  10. Landing Gear System
  11. Navigation System
  12. Communication System
  13. Data Transfer and Storage System
  14. Flight Director/Flight Management System
  15. Cargo Ramp and Door
  16. Minotaur Mission System to include RADAR (APS 143) and Forward Looking Infrared (FLIR) inputs

MTU General Requirements:

The contractor shall:

1.  Convert the existing CN-235-100 hull into an integrated HC-144B MTU with hands-on, real aircraft hardware and components as well as simulated and virtual systems and components.  All virtual/simulated systems shall accurately reflect the real or actual system.  All systems and components are required  to communicate with each other during MPC procedural steps and respond correctly to inputs from real, simulated and/or virtual switches, circuit breakers, power levers, condition levers and fire handles.  

2.  Install the following systems/components (GFE):

    a.  Flight control components –  wings, horizontal and vertical tails/stabilizers, ailerons, elevators, rudder, flaps, aileron/rudder/elevator trim tabs, servos and actuators.

    b.  Cockpit Flight Controls – yokes, throttle quadrants, and rudder pedals

    c.  Hydraulic system components – reservoir, pumps, valves, lines, accumulators etc.

    d. 1 engine, 1 propeller, and all accessory and auxiliary components required for mounting the engine to the airframe

3.  Assemble and configure the hull/components at either the contractor’s site or at the Avaition Technical Training Center (ATTC) in Elizibeth City, North Carolina.  If assembled at the contractor’s site, the contractor shall coordinate pick-up, shipment and delivery of parts, components, and aircraft hull to the contractor’s facilities and delivery of aircraft/MTU back to ATTC.  If assembly and configuration would be more cost effective /or more efficient to complete at ATTC by a contractor team, then the contractor shall provide a reflective cost estimate.

4.  Ensure the MTU device meets the ELO, critical tasks, and USCG identified faults associated with the AET and AMT “A” and “C” School training requirements.

5. Build and install floor panels that that can support 350lb per sq ft. or greater. Panels shall fasten to the deck support structure and allow access to each void individually.

6.  Build the “designated area” locations (fuselage sections 18, 21-24, 25-36, 41, and 52) so they visually and physically replicate the actual system (operational functionality is not required). 

7.  Design and develop a Commercial-Off-the-Shelf (COTS) hardware and software open architecture integrated solution for the MTU that meets both the AMT and AET ELO.  The MTU shall have a combination of real and virtual systems and components.  The AMT ELOs are typically met by hands-on interactions with  real, physical components and parts.  The AET ELO can be met by a combination of real, simulated and virtual systems and components.  All simulated components shall be within 10% of actual component weight for Remove & Install (R&I) fidelity.

8.  The MTU device shall have an integrated Fault Isolation System (FIS) capable of a variety of aircraft system faults, to include shorts, cross shorts and avionics software and data bus failures.  The induction shall be instantaneous and shall manifest precisely as it would in an operational HC-144B aircraft. The FIS shall be capable of completing no less than 18 AMT and 71 AET FIS  and shall allow all Terminal Performance Objectives to be met.

9. The MTU shall be ready for training within 24 months from contract award.

10. Provide sustainment support for up to 24 months post MTU delivery (design dependent). Sustainment support should consider the following items:

  • Non-recurring Engineering efforts
  • Technical integration support
  • Hardware and structural corrective maintenance
  • Windows 10 compliance and integration
  • Design, update or modify software code
  • Fault system components and hardware sparing
  • Software maintenance, configuration management and documentation support
  • Software troubleshooting procedures

11. Generate drawings for any new configurations.

12. Strip, prime and paint the aircraft for corrosion protection.
