OVERHAUL OF THE WHEELS, BRAKES AND ASSOCIATED COMPONENTS IN SUPPORT

OF THE HC-144 AND HC-27J AIRCRAFTS

STATEMENT OF WORK

1. BACKGROUND

The United States Coast Guard (USCG) has integrated fourteen (14) HC-27Js into the Medium

Range Surveillance (MRS) aircraft fleet, along with eighteen (18) HC-144 Ocean Sentries. The

HC-27J is a medium-sized military transport aircraft manufactured by Leonardo S.p.A, and the

HC-144 is a medium-range surveillance aircraft manufactured by Airbus Group. These aircraft are specifically equipped to perform all USCG missions, including search and rescue, maritime safety, security, logistics, national defense, and protection of natural resources.

2. SCOPE

The contractor shall overhaul the HC-27J and HC-144 aircraft wheels and brakes as required by the USCG. The parts listed in Section 3 must be overhauled by the Original Equipment

Manufacturer (OEM) or an OEM authorized overhaul center. The overhaul center must also be a

Federal Aviation Administration (FAA) Authorized overhaul center deemed acceptable by the

USCG and have experience effectively overhauling the wheels, brakes, and associated components for this requirement.

3. REQUIREMENTS

The parts below are included in this requirement:

The overhaul station must provide documentation confirming that it is either the Original

Equipment Manufacturer (OEM) or an OEM Authorized Overhaul Center. The overhaul center is required to comply with OEM specifications, including the OEM Component Maintenance

Manual (CMM), drawings, Service Bulletins, Overhaul and Repair Instructions (ORI), final acceptance testing, and, at a minimum, the performance requirements outlined in the OEM technical specifications current at the time of contract award. Additionally, the contractor must be

ISO 9000 compliant or maintain a quality system deemed acceptable by the USCG. The OEM for these wheel and brake assemblies is Meggitt Aircraft Braking Systems Corporation.

OEM drawings, Service Bulletins, and CMMs are proprietary and cannot be provided by the

USCG. The contractor is responsible for obtaining the required OEM drawings, Service Bulletins, CMMs, and specifications independently, as the USCG does not own or have access to this data.

The contractor shall supply all parts, labor, tooling, test equipment, and facilities necessary to perform the overhaul of the components included in this requirement. Only new replacement parts with traceability to the OEM will be accepted. All components must be overhauled in

Upon receipt of the unserviceable component, the contractor shall inspect for missing parts and notify the Contracting Officer in writing within fifteen (15) calendar days of any missing parts, including their part numbers. The contractor must also provide a Teardown and Inspection Report

(TIR) that identifies part numbers and nomenclature for all parts requiring overhaul or replacement to ensure the component is Ready for Issue (RFI). The TIR shall include the part numbers, unit prices for replacement parts, labor hours, labor rates, and any additional charges applicable. A copy of the Inspection Report must be submitted to the Contracting Officer within five (5) calendar days of the component inspection.

All parts must be thoroughly cleaned in accordance with applicable Component Maintenance

Manuals or FAA Advisory Circular 43-205, Guidance for Selecting Chemical Agents and

Processes for De-painting and General Cleaning of Aircraft and Aviation Products, to ensure they are as free as practical of hazardous dust, including hexavalent chromium, cadmium, and lead, before being returned to the Aviation Logistics Center (ALC). The ALC reserves the right to conduct random sampling of parts to ensure compliance with these requirements. Additional information on these hazards can be found in Occupational Safety and Health Standards

1910.1025 (Lead), 1910.1026 (Hexavalent Chromium), and 1910.1027 (Cadmium).

The required turnaround time for the overhaul is ninety (90) days after receipt of material (ARM).

Earlier delivery is preferred, provided there are no additional charges to the Government.

Finally, the USCG requires the replacement of all HC-144 wheel bearing races during each overhaul cycle.

4. MATERIAL TRACKING SYSTEM REQUIREMENTS.

The USCG tracks serial number components via the USCG’s Aviation Computerized Maintenance

System (ACMS). This tracking provides a historical record of overhaul, maintenance, and item location and status. It also provides an effective method of configuration control. All components will have a Significant Component History Report (SCHR) and a Component Repair Record (CRR).

No SCHR action is required by the contractor except to ensure the SCHR remains with the component.

The contractor shall maintain a legible Component Repair Record for each tracked component.

The tracking form shall show the component's part number, nomenclature, serial number and specific rework performed including labor hours and materials. In addition, the contractor shall review all manufacturer's service bulletins, service information letters and component revisions for applicability against the part number of the components included in this contract. The contractor shall indicate on the tracking form those service bulletins which are applicable and whether or not they have been installed on each component included in this contract. The specific form

(ie...Contractor’s existing form) to be used shall be submitted with the contractor's proposal, at which time it will be reviewed for the required information and acceptability by the Contracting

Officer. Within five calendar days after rework completion two legible copies of the tracking form are to be distributed as follows:

A. One copy shall be placed inside of the shipping container with the reworked component.

B. One copy shall be mailed to the following address:

Delivery Order Number: (To be assigned at time of award)

5. INSPECTION AND ACCEPTANCE

Inspection and acceptance will be performed by the USCG, ALC Quality Assurance personnel for count and condition only. The Contractor shall provide a Federal Aviation Administration (FAA) airworthiness 8130-3 Certificate or a Certificate of Conformance with each component. FAA form

8130 is preferred, however a Certificate of conformance is acceptable if it is in accordance with

FAR 52.246-15. These forms shall be attached to each part and copies should be included with the packaging slip and the invoice.

6. PACKAGING AND DELIVERY

Unless otherwise specified, packaging and preservation shall comply with the Component

Maintenance Manual (CMM). Components must be packaged to ensure maximum protection from damage during transit and corrosion. All items must be shipped in accordance with ASTM D

3951-10. Each package must be labeled clearly on the outside with the following information:

• National Stock Number (NSN)

• Part Number

• Serial Number

• Nomenclature

• Contract Number

• Delivery Order Number

• CLIN

• Vendor CAGE Code

The Material Inspection and Receiving Report (e.g., commercial packing slip, DD Form 250, etc.)

and Certificates of Conformance must be placed on the outside of individual containers. If traceability to the OEM is required, documentation proving such traceability must be included inside the shipment container.

Internal packaging materials must be sufficient to prevent damage during shipment, handling, and storage. Preservation protection must prevent corrosion, deterioration, and decay during warehouse storage for a minimum period of one year. The following packaging materials are not permitted:

• Popcorn

• Shredded paper

• Styrofoam

• Any type of peanut packaging

Barcoding is authorized but not required.

Each component will be shipped from the USCG to the contractor in a wooden crate to prevent damage during shipment. Upon completion of the overhaul, the contractor must ensure all components are properly packaged and returned to the USCG using the USCG-provided wooden crate, unless otherwise specified.

If the wooden crate is damaged upon arrival at the contractor's facility, the contractor must notify the USCG Contracting Officer within one (1) business day to address the issue. The contractor may be held responsible for any damage to the components if the wooden crate is not used for return shipment.
