Troubleshooting Recommendations:
- Check if there is damage to the sensor and nose gear harness.
- If there is damage to the sensor or harness, replace nose gear harness and do close out.
- If there is no damage, continue with the next step.
- Check if there damage to the RH WOFW sensor target.
- If there is damage, replace the RH WOFW sensor target and do close out.
- If there is no damage, continue with the next step.
- Perform the adjustment of the nose-gear weight-off-wheels (WOFW) proximity-sensor AMM task 32-61-05-820-807. Is the fault still present?
- If NO, do close out.
- If YES, continue with next step.
- Access and disconnect the Right NLG WOFW Sensors. Perform a continuity check as follows:
From To Result PW2-R PW2-S - If there is no continuity, RH nose gear harness and continue with the next step.
- If there is continuity, continue with next step.
- Perform the continuity check as follow:
From To Result A52AP1-A3 P216-31 A52AP1-B3 P216-32 J216-31 JW2-R J216-32 JW2-S - If there is no continuity, repair defective wiring as required and do close out.
- If there is continuity, continue with the next step.
- Perform a continuity check as follows:
From To Result A52AP1-A3 Ground A52AP1-B3 Ground - If there is continuity, repair defective wiring as required and do close out.
- If there is no continuity, continue with next step.
- Replace the Right WOFW sensor and target.
- Do close out.
