Troubleshooting Recommendations:
- Access the Nose Landing Gear (NLG) door assembly. Check if there is damage to the NLG door uplock proximity sensor and wiring.
- If damage is found, go to step 7.
- If no damage is found, continue with the next step.
- Check if there is damage in the Nose gear door uplock sensor target.
- If damage is found, replace the Nose gear door uplock sensor target and do close out.
- If no damage is found, continue with the next step.
- Perform the adjustment of the Nose-gear door-uplock proximity sensors AMM task 32-61-05-820-803. Is the fault still present?
- If NO, do close out.
- If YES, continue with next step.
- Perform a continuity check between the pins of the connector P106 (NOSE LD/GR BULKHEAD (FS202.00 RHS)) as follows:
From To Result P106-E P106-F - If there is no continuity, go to step 7.
- If there is continuity, continue with next step.
- Remove the LGECU. Perform a continuity check as follow:
From To Result A52BP1-G1 P214-99 A52BP1-H1 P214-100 J214-99 J106-E J214-100 J106-F - If there is no continuity, repair defective wiring as required and do close out.
- If there is continuity, continue with next step.
- Perform a continuity check as follows:
From To Result J106-E Ground J106-F 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 Nose Gear Door-Uplock Proximity sensor.
- Do close out.
