U.S. COAST GUARDHU25 ATF3-6 ENGINE NOSE COWLING (PN 553-0170 SERIES) REPAIR STATEMENT OF OBJECTIVES 1.0 BACKGROUND The U.S. Coast Guard currently operates twenty (20) HU-25 aircraft manufactured between 1982 and 1984 by Dassault-Breguet Aviation SA-Avions Marcel (Falcon Jet Corporation). Each aircraft is equipped with two Honeywell ATF3-6 fan jet engines. Typical failure modes of ATF3-6 engine nose cowlings are material cracks that propagate as a result of various environmental factors. Some of these include: vibration, corrosion, thermal fatigue and erosion. These failures occur primarily at the nose cowling nose lip rivet lines. Past history shows that a complete or partial disassembly of the nose cowling is necessary for thorough inspection and repair or replacement of damaged components. 2.0 OBJECTIVE A. The Coast Guard’s objective is to obtain services of a Federal Aviation Administration (FAA) authorized repair center to effectively repair and provide complete, ready-to-install HU-25 ATF3-6 nose cowling assemblies. Repaired nose cowlings must meet the Original equipment Manufacturer’s (OEM’s) form, fit and function specifications to ensure installation and operational characteristics are met. The contractor shall replace the original aluminum nose lip PN 553-0169-1 with a nose lip manufactured from 321 stainless steel. The stainless nose lip must meet all thermal properties as the aluminum nose lip. In addition, corrosion preventative measures shall be incorporated during repair. The offeror is responsible for all necessary functions to perform services requested. This includes, but is not limited, required tooling, test equipment, parts, material, engineering services, management, maintenance, preservation, shipping, etc., to repair nose cowlings. The offeror’s responsibilities to Coast Guard consist of preparing and submitting a detailed work specification and cost breakdown structure for repair and ensure that all Coast Guard Time Compliance Technical Orders (TCTOs) remain incorporated upon completion of work. Under a performance-based contract structure, performance metrics and service level agreements will be used to monitor the performance of this contract. The Coast Guard Aircraft Repair and Supply Center’s (ARSC) HU-25 Product Line and the winning offeror will baseline and monitor progress using agreed-to performance metrics and service level agreements. B. To meet the Coast Guard’s objectives the offeror will be required to meet the following criteria: 1. Technical a. Provide detailed work specifications for nose cowling repair. b. Provide a written Performance Metrics plan. c. Provide evidence of and ability to maintain a Quality System acceptable to the Coast Guard. d. Either possess or show ability to obtain adequate technical data, tooling and fixtures to meet the OEM’s form, fit and function characteristics. e. Provide separate cost breakdowns for nose cowling repair (labor and parts). Replacement nose lip shall be priced separately. Note 1: Exterior paint scheme for the engine nose cowling consists of AKZO Primer P/N 10P20-13and US Paint topcoat K8080. Note 2: Stop drilling of cracks or use of flush patches are considered temporary repairs and are not permissible repairs for the purpose of this contract. Note 3: Note: Modifications or acceptable alternatives must be approved by the U.S. Coast Guard’s HU-25 Engineering Cell at ARSC. 2. Past Performance a. Provide documentation for having performed repair of similar or like items. b. Provide Points of Contact for past performance documentation for the past two years. Include references’ name, company, phone number, and e-mail address. 3.0 APPLICABLE DOCUMENTS The following Technical Specifications are applicable: a.
