STATEMENT OF WORK (SOW)

OVERHAUL AND REPAIR OF THE 14RF-37 PROPELLER ASSEMBLY and COMPONENTS

70Z03824RL0000004

1.0 BACKGROUND

1.1 The Coast Guard currently operates Eighteen (18) HC-144 Maritime Patrol Aircraft each powered by two CT7-9C3 turboprop engines which use the model 14RF-37 Propeller. The aircraft is manufactured by AIRBUS MILITARY (formerly EADS CASA) in Seville, Spain. While the base CASA CN-235-300M MPSA aircraft provides the foundation for the

Coast Guard HC-144, changes to the base aircraft configuration and the addition of supplementary systems have been combined resulting in a CG01 version of the CN-235-

300M MPSA. The HC-144 aircraft is programmed to fly 1000 hours annually.

1.2 The Maritime Patrol & Surveillance Aircraft (MPSA) are operated differently from general aviation in support of Coast Guard operations which consist of Search and Rescue, Surveillance, and Reconnaissance missions. Coast Guard HC-144 missions require frequent operation at lower altitudes and in salt–laden environments. These environments contribute to an increase of corrosion on airframe structures, engines and components of the aircraft. The Aircraft and its components are inspected by Coast Guard personnel in accordance with (IAW) the Original Equipment Manufacturers’ (OEM) periodic requirements and in conjunction with the Coast Guard’s specialized Asset Computerized

Maintenance System (ACMS).

1.3 The original manufacturer, design authority and technical data rights owner of the components listed in the solicitation schedule was Hamilton Sundstrand Corporation.

Following corporate mergers with United Technologies Corporation (UTC) and most recently Collins Aerospace, design authority and ownership of component technical data transferred to Collins Aerospace. For this statement of work, the term OEM refers to the component technical authority and data rights originally established by Hamilton

Sundstrand/UTC but currently owned and managed by Collins Aerospace.

2.0 SCOPE

2.1 The scope is intended to establish overhaul and repair services for the listed Hamilton

Sundstrand manufactured parts (listed in the solicitation schedule). All are listed and are hereafter known as Hamilton Sundstrand components unless otherwise specified. This would include the complete teardown, inspection, rework, repair, assembly, and testing of all items identified in the Schedule IAW OEM specifications. This SOW establishes the minimum Coast Guard requirements necessary for overhaul and repairs, and is not intended to be all inclusive, nor detract from the procedures outlined in the manufacturer’s drawings, manuals, specifications, public & private action items and service bulletins.

3.0 REQUIREMENTS

3.1 The Coast Guard does not own, nor can it provide access to or copies of OEM publications. As such, the contractor must be able to receive all applicable OEM manuals and publications including but not limited to: Component Maintenance Manuals (CMM), Action Item (AI) Log (both public, and private/restricted), Revisions (Rev), Temporary

Revisions (TR), Service Bulletins (SB), Service Information Release (SIR), Modifications (MOD), Amendments (AMD), including contractor specifications and procedures applicable for the inspection, repair or overhaul of the scheduled components.

3.1.1 Contractors must demonstrate appropriate repair capabilities and provide proof of subscription to OEM publication(s) applicable to USCG components, including revisions and release of new AIs (both public and private/restricted).

3.2 The contractor shall be a certified Federal Aviation Administration (FAA) Part 145 authorized overhaul and repair center to effectively inspect, test, troubleshoot, clean, overhaul, repair and preserve the listed Hamilton Sundstrand components within this scope and requirements. Work must be performed IAW the most current Hamilton

Sundstrand or other OEM CMM, Public & Private AIs, REVs, TRs, and specifications, including SBs, SIRs, AMDs, and MODs to include any specified or proposed USCG publication(s).

3.3 At time of proposal submission, the contractor shall provide a current Capabilities list, REF: FAA part 145.215 and indicate the percentage of each repair/overhaul element(s) listed in the CMM, for hubs, blades, actuators, transfer tubes, bulkheads and retaining rings which are performed at the contractor’s facility for the identified operation. It is requested that contractors maintain on-site capability to perform applicable repair and overhaul procedures which may include the cut and cold roll rework processing per engineering drawing SK122836.

3.3.1 In cases where this and other actions are not performed directly by the contractor, the USCG requests notification of the intent to sub-contract including the nature of the actions and the vendor selected to perform the work. The prime contractor will remain responsible for the quality assurances, airworthiness, and schedule impacts of such arrangements.

3.4 If the contractor loses its FAA part 145 certification during the period of performance, this constitutes a material breach of contract which may, at the discretion of the

Contracting Officer, result in contract termination. The contractor shall notify the

Contracting Officer verbally and in writing, no later than five (5) calendar days after certification forfeiture and disclose all facts relevant to the forfeiture.

3.5 The contractor shall be responsible for all necessary functions to perform the contracted services requested. This includes, but is not limited to, required tooling, manuals, test equipment, parts, material, engineering services, management, personnel, documentation, preservation, shipping, etc.

3.6 The Coast Guard anticipates at least two levels of service; “Repair” and “Overhaul”.

3.6.1 “Repair” - “Return to Service,” which is considered inspect, repair, and test as necessary. This work consists of inspection and analysis usually of a specific defective condition, repair of that condition, replacement of defective parts only as necessary, and testing to meet the OEM’s functional return to service requirements.

3.6.1.1 A repair shall not zero the Time Since Overhaul (TSO), component time continues for repaired items.

3.6.1.2 All parts sent to the contractor under the repair level of service shall be returned to the Coast Guard within 45 calendar days After Receipt of

Material (ARM) at the contractor’s facility.

3.6.1.3 Parts shall be returned in Ready For Issue (RFI) condition, and be shipped to the Coast Guard’s ALC facility unless directed otherwise by the contracting Officer by contract modification.

3.6.2 “Overhaul” (Major Inspection) - “High Time,” having reached one of the OEM’s airworthiness limitations for any life cycle limits or having some other general condition (out-of-limit/out-of-tolerance) such as excessive wear and tear, damage, or corrosion, as deemed to require a major inspection or overhaul level of service.

3.6.2.1 Components identified in advance by the USCG as requiring “Overhaul” service will be funded at the negotiated “Overhaul” Firm Fixed Price rate.

However, during the inspection of a component which was shipped/funded as a “Repair,” it may become evident that an “Overhaul” is warranted. In this case, the contractor shall contact the USCG and provide the justification for the amendment for the subject item and shall receive authorization before proceeding with “Overhaul” services.

3.6.2.2 An “Overhaul” shall be considered as the next higher level of service beyond the “Repair” scope; it shall include the complete teardown, inspection, rework, assembly, and testing of components, to OEM original or rebuilt specifications. An “overhaul” shall zero the TSO and effectively restart intervals and OEM component life cycle limits as applicable.

3.6.2.3 All parts sent to the contractor under the “overhaul” level of service shall be returned to the Coast Guard within 60 calendar days After Receipt of

Material (ARM) at the contractors facility.

3.6.2.4 Parts shall be returned in RFI condition and be shipped to the Coast

Guard’s ALC facility unless directed otherwise by the Contracting Officer by contract modification.

3.7 During Overhaul of all 14RF-37 Propeller Hubs (814721-2), the contractor shall provide

100% replacement of the following parts within the firm fixed price structure of the contract, regardless of whether the hub was configured with these parts upon receipt by the contractor: Outer Bearing Race (782674-1) and Race Barrel Retainers (789263-1), Shim (820475-1) and Glide Ring (790098-4), Dowel Pin Composite Bushing Shim

(815597-1).

3.8 During both repair and overhaul of propeller blades, the contractor shall paint all 14RF-

37 propeller blade tips White (Paint P/N 55W002) 5.75 to 6.25 inches from the blade tip with White paint that meets MIL-PRF-85285 standard and FED-STD-595 (17925).

3.9 The contractor shall provide new blade seals P/N 817387-3 for all 14RF-37 Propeller blades regardless of repair or overhaul within the firm fixed price structure of the contract.

3.10 The contractor shall inspect and replace, the ball bearings (PN69992A16) and carrier

(PN782673-1) on condition, during repair and provide for 100% replacement of the ball bearings (PN69992A16) and on condition replacement of the carrier (PN782673-1) during overhaul of the 14RF-37 propeller blades.

3.11 Missing Components: the contractor shall notify the Contracting Officer in writing of any missing parts or sub-assemblies required for final inspection and acceptance, within ten

(10) working days after the receipt and inspection of the components. The Contracting

Officer will then have forty-five (45) calendar days to provide formal disposition instructions to the contractor. This is particularly the case for propeller hubs subject to repair service, as they must be returned in an RFI condition. The Coast Guard reserves the right to provide RFI or repairable parts.

3.11.1 Turn-Around-Time (TAT) stops as of the date of the correspondence giving notification that work must cease due to missing parts. Unless the Contracting

Officer elects to have the component returned to the Coast Guard as is, the TAT will re-start at a mutually agreed date stated in the bilateral modification.

3.12 During both repair and overhaul, the contractor shall maintain all existing SBs

(Mandatory and Optional), public & private AIs and other amendments or modifications previously incorporated on USCG components unless appropriately superseded or as directed by the Contracting Officer.

3.12.1 SB and AI configurations are subject to change during the contract period. SBs, AIs (both public & private), and modifications not previously incorporated shall be identified in writing to the Contracting Officer.

3.12.2 Upon receipt of notification from the OEM that a SB, AI (public & private), MOD or other applicable publication revision, the contractor shall review and evaluate the change and submit, within ten (10) calendar days after receipt of that notification, a firm-fixed price proposal for the change to be applied.

3.12.2.1 The proposal shall contain a breakdown of material and labor costs including hours, labor categories, labor rates, and applicable mark ups.

Upon completion of negotiations, a contract modification will be issued to reflect the change, and the service bulletin shall be incorporated into each subsequent component received at the contractor’s facility.

3.12.2.2 When incorporation of such revisions changes a components part number, the new part number shall be added to the contract. The same procedures apply if removal of service bulletins is required.

3.12.2.3 Incorporation of some revisions may result in superseded parts. In cases where older components cannot be modified/upgraded to newer configurations, the contractor shall notify and request disposition instructions from the Contracting Officer for superseded parts.

3.12.2.4 Unless the contractor has a signed contract modification permitting a change and bearing the signature of a Contracting Officer, funding has not been authorized.

3.12.3 The contractor shall implement Action Item D1155-AI10819 to all USCG propeller hubs during all repairs and/or overhauls.

3.13 Teardown Inspection Reports (TIR)

3.13.1 TIRs, are required under certain conditions, such as components deemed unrepairable IAW the publications accessible to the contractor in 3.1 and 3.1.1.

TIRs may also be requested for Engineering incident, safety investigations, warranty determination, or for other failure analysis.

3.13.2 The cost for development of TIR reports shall be inclusive within the Firm Fixed

Price structure of the contract for all repair and/or overhaul level services.

3.13.3 Upon request, the contractor shall within ten calendar days provide a copy of the

TIR to the Contracting Officer. TIRs, when requested, shall be forwarded to the

Contracting Officer prior to commencement of repair or overhaul work.

3.13.4 TIRs shall include: nomenclature, NSNs, P/Ns, S/Ns, Contract number, Delivery

Order numbers, CLINs, as well as descriptions of conditions found, photos, illustrations, and drawings, as necessary to identify the reasons for failure and/or rejection before and during teardown. The TIR shall provide clear documentation as to the failure and/or rejection and shall, where applicable, list all parts and costs as would be required for repair/overhaul of the component or assembly. The TIR shall also list all tolerances, and/or specification(s) which are out of limits to include CMM reference and the exact location on the component with the associated discrepancy measurements and photographs.

3.14 Beyond Economical Repair (BER):

3.14.1 Components might be deemed BER when the cost of returning the CLIN part to serviceable condition, exceeds the current replacement cost of that part; or when the part cannot be repaired or overhauled due to damage or wear beyond the material properties, characteristic, or specifications of the item. The following procedures shall apply to components considered to be in a BER condition.

3.14.1.1 The contractor shall contact the Contracting Officer, in writing, via e-mail, with specific rationale for the BER condition including a complete TIR submission.

3.14.2 Once a component is determined to be BER by the USCG, no further repair or overhaul work shall be performed and the item in question shall be returned to the

USCG. BER components will normally be returned to USCG for physical disposition.

3.14.3 Alternative disposition instructions, such as decision to repair at cost greater than replacement cost may be necessary from time to time given supply chain limitation. Such alternative disposition shall be received in writing from the

Contracting Officer prior to any further repair actions being taken on the subject part.

3.15 Corrosion expectations:

3.15.1 Low altitude flight over salt water contributes to greater corrosion in Coast Guard components than typical commercial operators. The contractor shall consider the presence and effects of corrosion to be "normal" and provide for correction and removal of corrosion within the firm fixed repair/overhaul price. During inspection and functional testing, the presence of corrosion in an item or part shall constitute reason for a more thorough disassembly and inspection.

3.15.2 Corroded parts shall be replaced, except where removal of corrosion from a part is authorized. Corrosion removal and treatment of any affected areas shall be accomplished IAW the applicable CMM or other published OEM repair procedures.

3.16 Exclusions: Components received in the following conditions are to be considered exclusions and may indicate an exclusion from the price in the contract schedule:

Catastrophic crash damage, Non-crash related localized foreign object impact damage, domestic object damage traceable to a Coast Guard documented repair on the Hamilton

Sundstrand components, Acts of God, war, and alteration, modification or repairs that were not completed IAW technical data approved by the OEM, or the Coast Guard.

Conditions of corrosion shall not be classified as exclusions, see paragraph above.

3.16.1 If a component is considered (by the contractor) to fit the exclusion description, the contractor shall notify the Contracting Officer within 10 working days and submit a TIR noting the observed conditions. The contractor shall discontinue all actions until the Contracting Officer provides guidance. The USCG reserves the right to appoint a Representative to witness the remaining teardown and inspection of the component. A letter of notification and the Teardown Inspection Report

(TIR) shall be submitted to the Contracting Officer for disposition of the component. The contractor shall make the affected equipment available to a Coast

Guard Representative to view the exclusionary damage. If the Government elects not to physically view the equipment, the contractor’s findings report shall stand.

3.16.2 Upon request by the Contracting Officer, the contractor shall submit a firm fixed price proposal to include an itemized breakdown of material including nomenclature, part number, cost, and quantity of replacement parts, replacement percentages used to develop the original firm fixed contract price and the number of labor hours using established labor rates necessary to repair and/or restore exclusionary damage. This proposal shall include all necessary supporting rationale and shall be submitted within forty-five (45) calendar days after notification is given to the Contracting Officer. Upon completion of negotiations, the Contracting Officer may authorize repair/overhaul, via contract modification.

3.17 The contractor shall track and document calendar time, flight time, flight/life cycles, for all work and services performed on the Hamilton Sundstrand components as required under Coast Guard Asset Computerized Maintenance System (ACMS). See Section 6.0 for specific information.
