TO 1-1-700 MIL-PRF-81733, SEALING AND COATING COMPOUND, CORROSION INHIBITIVE 48 PR-1773, SEALING COMPOUND, LOW ADHESION, NON-CHROMATE CORROSION INHIBITORS 57 SAE AMS-3276 (MIL-S-83430), SEALING COMPOUND, INTEGRAL FUEL TANK 59 a. Apply MIL-PRF-81733, Type II-1/2, Class I, Grade A, PR-1773, Class B-1/2, or SAE AMS-3276, Class B-1/2 sealant, preferably with a sealant gun. The new sealant should match the configuration of the removed sealant but should be of sufficient depth to ensure contact with the mating surface. 12.7.6 SAE AMS 3255 EPTFE (Skyflex®) and Av- DEC® HT3000 and HT3935-7 Sealing Tape Gasket Repair. In order to preserve seal integrity, it is necessary to inspect the sealant tape each time an access panel is removed. NOTE • The main function of the pressure sensitive adhesive backing on the SAE AMS 3255 (Skyflex®) sealant tape is to hold the EPTFE sealant tape in place during access door/panel assembly. The adhesive on one side of the Av-DEC® HT3000 sealant tape acts as a seal as well as holding the sealant tape in place. Peeling/delamination of the adhesive from the equipment frame flange or access door/ panel requires replacement of the sealant tape if the tape is no longer located in the faying surface. Visually inspect sealant tape material for nicks, cuts, gouges and delamination/separation. • Av-DEC® HT3935-7 sealing tape requires complete replacement each time an access door/panel sealed with it is removed as it has an adhesive on both sides. Scrape the old tape off with a plastic tool, and apply a new length of tape as done originally. a. Cut and remove damaged section of sealant tape. MIL-PRF-32033, LUBRICATING OIL, GENERAL PURPOSE, PRESERVATIVE (WATER-DISPLACING, LOW TEMPERATURE) 41 VV-P-236, PETROLATUM 68 b. Apply a very thin film of MIL-PRF-32033 (VV-L-800), Oil or VV-P-236, Petrolatum, to the mating surface of the access door/panel and close and/or install the access door/panel. If installed with fasteners, lubricate them with the same material used on the door/panel mating surface, install 1/2 of the required fasteners (every other fastener), and torque to 1/2 to 3/4 of the specified torque for the assembly. c. Do not open or remove the door/panel for a minimum of 24 hours. b. Measure and cut a new piece of SAE AMS 3255 (Skyflex®) or Av-DEC® HT3000 sealant tape approximately one inch longer than the removed section. c. Peel the non-stick backing paper off and install a new section of sealant tape so it overlaps the previously installed sealant tape by one-quarter to one-half of an inch on each side of the repair site. NOTE Ends of the repair splice must overlap the existing sealant tape to ensure seal integrity. Use care not to pull or stretch the sealant tape patch as it is applied. The stretched AMS 3255 EPTFE and Av-DEC® HT3000 sealant tape patches will retract even if clamped between faying surfaces, and inadequate sealing may result. d. Once the sealant tape patch is applied, run fingers back and forth on the upper surface of the sealant tape patch to promote adherence of the adhesive. 12-32
TO 1-1-700 NOTE Applying a small amount of extra pressure to the upper surface of the sealant tape patch will cause the pressure sensitive adhesive to adhere better to the faying surface and overlapped areas of old sealant tape and it will create indentations/discoloration at the fastener holes allowing for easier location/identification. e. Puncture any affected fastener holes with a sharp pointed object such as an awl or a scribe. Figure 12-11. Typical Injection Seal Figure 12-10. Typical Fillet Seal 12-33
