Fault Description:
Bleed Management Controller (BMC) 2 senses that the Secondary Power Distribution Assembly (SPDA) 3 does not supply 28 VDC from its sensors output. Inhibited during Take-Off and Landing.
Possible Causes:
- Secondary Power Distribution Assembly (SPDA) 3 (A15)
- Bleed Management Controller (BMC) 2 (A70)
- Junction Box (JB3)
- Right Bleed Pressure Transducer (MT112)
- Right Intermediate Pressure Transducer (IPPT)
- Right Cowl Anti-Icing Pressure Transducer (CAIPT)
- Associated Wiring

Troubleshooting Recommendations:
- Swap SPDA 3 with SPDA 2.
- If system checks are good, replace SPDA 3 and do close out.
- If fault remains, continue with next step.
- Perform wiring checks between SPDA 3, JB3, R BPT, R IPPT, R CAIPT and BMC 2.
- If wiring checks are not good, repair defective wiring as required and do close out.
- If wiring checks are good, continue with next step.
NOTE: Remove all interface components for short test.
- Swap Right BPT with Left BPT.
- If system checks are good, replace Right BPT and do close out.
- If fault remains, continue with next step.
- Swap Right IPPT with Left IPPT.
- If system checks are good, replace Right IPPT and do close out.
- If fault remains, continue with next step.
- Swap BMC 2 with BMC 1.
- If system checks are good, replace BMC 2 and do close out.
- If fault remains, continue with next step.
- Replace cowl anti-ice valve.
- If system checks are good, do close out.
- If fault remains, continue with next step.
- Replace JB3.
- Do close out.
