1. DESCRIPTION OF SERVICES:

1.1. The contractor shall provide all management, tools, supplies, equipment, and labor necessary to apply phosphate-fluoride and primer to B-2 Landing Gear Components. The PWS specifies the general instructions, engineering procedures, and requirements for phosphate-fluoride coating and primer coating of B2 titanium landing gear components.

2. BASIC SERVICES:

2.1. Stripping and priming parts will be performed and assets returned for review/approval to Hill Air Force Base (AFB) within 30 calendar days of receipt.

2.2. The government will deliver the asset(s) to the contractor’s facility.

2.3. The contractor shall deliver the asset(s) to the government facility (Hill AFB) after processing.

2.4. The contractor shall inform the Evaluation & Inspection Engineer, Contracting Officer, Depot Expert/Engineer and the CMXG business office via their Hill AFB government Email of all delivery times, pick up times, and expected delays.

2.5. The contractor shall strip any remaining phosphate-fluoride coating prior to application of new phosphate-fluoride coating.

2.6. The contractor shall prepare the surfaces and apply phosphate-fluoride coating to the B-2 landing gear components In Accordance With (IAW) Aerospace Material Specification (AMS) 2486.

2.7. The contractor shall prime the components with MIL-PRF-23377 TYPE I, CLASS C (primer coating, epoxy, high solids) or MIL-PRF-85582 TYPE I, CLASS C2 (primer coating, epoxy, waterborne). The primer thickness shall be 0.0006-0.0013”. Parts must be primed within 24 hours of completing the phosphate fluoride coating process. The applied primer shall be free of runs, wrinkling, crazing, blistering, lifting, pitting, cupping or other defects. Lubrication holes and noted interior diameters (see drawings below in Appendix B, areas to be omitted have been highlighted) shall not be coated with primer (CDRL A001).

2.8. Individual part requirements: Many of the figures below (see Appendix B) show the entire assembly including bushings, springs, screws, nuts, etc. All components will require removal of the old phosphate-fluoride coating and application of the new phosphate-fluoride coating to the entire surface of the part (unless otherwise noted in the drawing). The government will disassemble all assemblies into individual components at Hill AFB. Paint and primer will also be removed by Hill AFB. The phosphate fluoride coating is only required on the titanium components in the assembly. Masking may be required as specified in the attached drawings for paint.

2.9. The contractor shall provide Certificate of Compliance with each returned component and a copy submitted via email to including the following: (CDRL A001)

2.9.1. The time and date the phosphate-fluoride process was completed.

2.9.2. Dry film thickness of applied primer.

2.9.3. The time and date the primer was applied.

2.9.4. This documentation shall be provided to Hill AFB with the shipment of each component. This documentation shall be maintained by the contractor for two years from when the parts are processed. It shall be made available to Hill AFB personnel; Contracting Officer, the Engineer, and the CMXG business office via their Hill AFB government Email upon request.
