Installing The CSU-15/P Anti-g Garment Hose

Installing The CSU-15/P Anti-g Garment Hose This anti-g hose also must be cut to size, and an end fitting installed after correct garment size has been determined. To fit the anti-g hose, proceed as follows: Have the aircrew member don the anti-g garment and sit in the aircraft. Attach the quick disconnect on the hose to the aircraft supply system. If the hose is too long, measure it and mark where to cut it. Lay the hose out flat. In a single operation, cut the outer covering, inner hose, and spacer/reinforcement at the mark. Sear completely around the end of the outer cover to prevent fraying. Remove the tape, clamp, and severed portion of hose from the quick-disconnect connector. Position the spacer/reinforcement on the rubber extension of the connector (fig. 4-12). Butt the end against the raised portion of the connector, and cover it with three turns of electrical tape. Slide the inner hose (bladder material) over the connector and butt it against the raised portion of the connector. Ensure the spacer/reinforcement is not twisted. Secure it with three turns of tape. NOTE: In some instances it may be necessary to build up the outside diameter of the hose area under the clamp with three to six turns of tape to get the clamp tight. Slide the outer cover of the hose over the inner hose until it butts against the raised portion of the connector. Install a clamp as shown in figure 4-12. Cover the clamp with three turns of tape or a heat-shrinkable insulation sleeve. Figure 4-12.-Assembly of hose and quick-disconnect fitting. Finally, ensure that the fitting is properly inserted in the hose, and clamp it properly positioned between the raised bead and the body. Ensure that the clamp is tightened sufficiently by grasping the hose and fitting and jerking sharply. Inspections A preflight inspection is performed by the aircrew member before each flight. The interval between preflight inspections must not exceed 14 days. To perform the preflight inspection, do the following: l Check the slide fasteners for secure attachment, ease of operation, and corrosion. l Visually inspect all seams for loose or broken stitching. . Visually inspect outer shell and hose covering for holes, tears, and abrasion. . Check the quick-disconnect connector for nicks, corrosion, and proper operation. . Inspect the laces and lacer loops for secure attachment and excessive wear. If you find any discrepancies, forward the garment to the aviator’s equipment branch for a periodic inspection. The calendar inspection is made by an Aircrew Survival Equipmentman prior to placing the anti-g garment in service and every 180 days after that, which coincides with every second life preserver calendar inspection. The calendar inspection is also done whenever a discrepancy is discovered during preflight inspection. This inspection consists of the preflight inspection items and the following additional tasks: You will be required to perform a leak test and repair any discrepancies found after you complete the leakage test. To perform the leakage test on a CSU-15/P anti-g garment, you should use a special test fixture, which inflates the suit and measures the inside pressure. You are required to inflate the g-suit to 5 psi. The bladder must not drop more than 1.0 psig in 30 seconds. A pressure drop greater than 1.0 psi in 30 seconds constitutes a failure. The CSU-15/P anti-g garment remains in service until it fails the leakage test. If everything is in order, date and sign the history card. 4 - 14
