INSPECT
Inspect the actuator assembly in accordance with WP 0005 00, using the procedures in Table 1, as well as
the following procedures:
1. All actuator assemblies must be checked prior to every airdrop.
2. Inspect the actuator spring guide rod as follows:
a.
Rotate the actuator arm clockwise until the spring guide rod is fully extended and lock the actuator
arm into position with the appropriate quick release pin.
b.
Place a 2-inch straight edge (or equivalent) on the fork end of the spring guide rod.
c.
If spring guide rod shows any bend or curvature against straight edge, remove EFTC from service.
3. Check for free movement of actuator arm latching pin as follows:
a.
Pull latch ring on side of actuator to determine if latch pin moves freely under force of latch spring.
b.
Slowly rotate actuator arm counterclockwise to ensure arm pushes in latch pin and latch pin snaps
back into position to secure the arm from rotating clockwise.
c.
If latch pin sticks in one position, check for binding, bends, dirt, or debris on the latch pin assembly
inside actuator. Remove dirt and foreign matter but if pin is bent, remove EFTC from service.
4. Once the EFTC has been mounted to the platform, check the latch assembly coupling IAW WP 0017 00.
