Repair Antennas for U.S. Coast Guard Aircraft HC-27J

Statement of Work (SOW)

To obtain services for the inspection, repair, and/or overhaul of specific aircraft components from an Original Equipment Manufacturer (OEM), an OEM Authorized Repair Center, or a Federal Aviation Administration (FAA) Certified 145 Repair Center acceptable to the Coast Guard.

• Components: The SOW specifies two types of antennas requiring service: National Stock Number (NSN) 5985-01-582-3944 (Part Number 12-190-6/1P24) requiring 3 each, and NSN 5985-99-549-9067 (Part Number 19-430-10N) requiring 2 each.

• Repair Levels: Services include "Inspect/Repair as necessary" and "Overhaul." Overhaul resets the component's Time Since Overhaul (TSO).

• Corrosion: Corrosion found during inspection requires thorough disassembly and repair/replacement according to OEM specifications. Corrosion on flight-critical components is not permitted and requires OEM evaluation.

• OEM Data: Contractors must obtain proprietary OEM drawings, Service Bulletins, Component Maintenance Manuals (CMMs), and specifications.

• Modifications: USCG modifications to original configurations must be retained unless specified otherwise.

• Cleaning: Components must be thoroughly cleaned to remove hazardous dust (e.g., hexavalent chromium, cadmium, lead) prior to return.

• Turn-Around Time: Required turn-around-time is ninety (90) days after receipt of material (ARM), with earlier delivery being desirable if no extra charges are incurred.

• Documentation: Contractors must provide a Federal Aviation Administration (FAA) airworthiness release 8130-3 Certificate or EASA Form-1 with each component. A Certificate of Conformance may be acceptable if authorized. A Teardown and Inspection Report (TIR) is required for all parts needing repair or replacement.

• Tracking: Contractors must maintain a legible component tracking form for each tracked component, including part number, nomenclature, serial number, and rework details.

Not explicitly stated in the provided SOW excerpt, but implies performance will be at the contractor's facility and components will be returned to the Coast Guard.

• Quality System: Contractor must be ISO 9000 compliant or have a quality system acceptable to the USCG.
• Airworthiness: All parts must be airworthy and suitable for installation on USCG aircraft.
• Packaging: Packaging must comply with CMMs, ATA specification number 300, and specific requirements for ESDS components. Packaging must prevent damage and corrosion during transit and storage for at least one year. Specific prohibited packaging materials are listed.
• Hazardous Materials: Compliance with Occupational Safety and Health Standards for lead, hexavalent chromium, and cadmium is required.
• Reporting: Contractors must notify the Contracting Officer (KO) of missing parts within fifteen calendar days of receipt and provide a copy of the Inspection Report within five calendar days of inspection.
• Acceptance: Final inspection and acceptance will be performed by ALC Quality Assurance personnel.

Justification for Other Than Full and Open Competition

This document outlines the justification for a sole-source acquisition of repair services for specific aircraft antennas. The U.S. Coast Guard (USCG) intends to test, evaluate, and repair two types of antennas: Antenna P/N: 12-190-6/IP24 (NSN: 5985-01-582-3944, Qty: 3) and Antenna P/N: 19-430-10N (NSN: 5985-99-549-9067, Qty: 2). These repairs are necessary due to corrosion and/or damage encountered during Product Depot Maintenance (PDM).

• Only One Source Reasonably Available: The justification is based on the unique nature of the items and the proprietary rights associated with their repair.

• Brand Name: The antennas are peculiar to one manufacturer, and their specific brand name, product, or feature is essential to the Government's requirements. Market research indicates that similar products lacking the particular feature do not meet, or cannot be modified to meet, the agency's needs.

• Chelton Limited (UEI: NAJKL26ADJL4)

  • Address: The Chelton Centre, Fourth Avenue, Marlow, Buckinghamshire, SL71TF

• The antennas are unique to a specific aircraft, and their installation, operation, or servicing must comply with the USCG's authorized engineering authority.

• Chelton, Inc. (OEM, Cage Code: 63563) owns all rights to the technical data, specifications, and drawings required for repair/overhaul.

• The Government does not own the rights to this technical data from sources other than the OEM or an OEM-approved source.

• It has been determined to be uneconomical for the Government to purchase these rights.

• Chelton Limited (Cage Code: U1907) is identified as the authorized OEM repair facility.

The following methods will be considered for determining fair and reasonable pricing:

• Market Research

• Comparison of proposed price with prices found reasonable on previous purchases

• Current Price List

• Comparison with similar items in a related industry

• Comparison to IGCE

• Contracting Officer's Personal Knowledge (to be explained)

• Other (to be explained)

• Purchase Request/Requisition Number: 2026006-ND02
