Task Instructions
1. The position of the locking pawl is sensed by a micro switch that rides on an hourglass-shaped pin pushed by the pawl. Push this pin in against its spring and verify that it moves freely. As the pin is pushed, two clicks from the switch should be heard as the switch roller follows the shape of the pin. Figure 459
2. The other micro switch senses the position of the lock handle. Gently deflect it, verify free motion and an audible click.
3. Further inspect the wing lock switch mounting plate assembly and replace any unserviceable parts. Be certain that the structure of the plate is not bent of damaged.
4. Connect the two micro switch connectors to the aircraft electrical harness.
a. LH lock mechanism: D9021P connects to D9021I. D9022P connects to D9022I.
b. RH lock mechanism: D9065P connects to D9065I. D9066P connects to D9066I.
5. Align the mounting holes and install the mounting plate assembly on the fuselage BL38 Rib with three 8-32 8C50MTT3 truss-head screws, torquing them each to 13 in-lbfwith a T15 Torx driver.
6. Install the wing fold lock handle. (Wing Lock Handle Installation)
