Hose, Hydraulic, High-Pressure

Tape

Saw

Vise

Procedural Steps:

a. Remove the damaged tube.

b. Measure the desired length of hose (see para 8-14). Hose may follow a different path than the

original tube and may be easier to install.

c. Squarely cut each end of the hose (see para 8-15).

d. Attach a fitting to each end of the replacement hose (see para 8-18).

e. Install the assembled hose.

f. Check that the hydraulic reservoir level is at least at the minimum operating level. If this level

low, refer to para 8-13 and fill the reservoir as needed.

g. Operate all hydraulic subsystems (except those that may still be damaged) to remove air from

the system. Check carefully for fluid leaks. Tighten leaking fittings.

h . Check the hydraulic reservoir again to ensure a sufficient hydraulic fluid level. If this level is low,

refer to para 8-13 and fill the reservoir as needed.

9. Record the BDAR action taken. When the mission is completed, as soon as practicable, repair

using standard maintenance procedures.
