9. Check the sealing compound on the aner-
oid screw, shown in figure 2-7. The seal must be
intact and undisturbed. Cracks due to normal
aging of seal material are acceptable.
10. Inspect the Teflon seal. Be sure that the
cup side of the seal is facing the piston (fig. 2-8).
FIRING ALTITUDE CHECK
To check for the proper firing altitude of the
automatic ripcord release, you must first be
familiar with the automatic parachute ripcord
release test set.
AUTOMATIC PARACHUTE RIPCORD
RELEASE TEST SET
The automatic parachute ripcord release test
set, shown in figure 2-9, is designed to test the
sensitivity of the automatic ripcord release to a
preset pressure altitude through use of an aneroid
The principal action that you test is the
consistency of the aneroid in actuating the release
mechanism at a predetermined altitude. To do
