9) Extend and retract the flaps, then check the travels - refer to 27-50-00.
10) Install the cowling under hull 218.

D. Replacement of "AVIAC" flap actuator with a "LPMI" flap actuator - Refer to Paragraph 6. "REPAIR -FLAP ACTUATOR"
3. ADJUSTMENT / TEST - FLAP ACTUATOR
A. Tools and consumable materials
- Flap travel jig 8650 TB20 00000
- Clinometer
B. Adjustment of landing gear / flaps warning signal and wing flap intermediate microswitches (Figures 202 and 203)
1) Set the intermediate microswitches (I.MS.) to obtain 10° ± 1° flaps extended and 11° ± 1° flaps retracted.
2) The design location of the extended intermediate microswitch (4) (E.I.MS.) is 0.039 in (1 mm) closer to the cam. Set the microswitches so that the extended intermediate microswitch (4) (E.I.MS.) triggers before the retracted intermediate microswitch (1) (R.I.MS.) during flap extension.
NOTE : If necessary, adjust with screws (3).
3) Similarly, the retracted intermediate microswitch (1) (R.I.MS.) will trigger before the extended intermediate microswitch (4) (E.I.MS.) during flap retraction.
4) The offset value between these microswitches must be determined by testing so that the flap actuator stops between the 2 microswitches in both directions of operation - see Figure 202.
5) The audible warning signal microswitch (2) must sound (landing gear not extended) from "flaps extended 15 to 20°" position to "flaps extended at 40°" position.
