Forum Articles/Infoservice/Newsletter: None

• Reset SECU1 circuit breaker 'SPOILER CTRL 1' CBP1-B9 if any of the inboard MFS and GS #2, #4, #5 and #7 surface indication are amber or magenta.
• Reset SECU2 circuit breaker 'SPOILER CTRL 2' CBP2-B9 if any of the inboard MFS and GS #1, #3, #6 and #8 surface indication are amber or magenta.

NOTE: It is not permissible to cycle the SECU 1 or 2 circuit breakers in the air.

1. Re-rig SECU 1.
2. Visually inspect the back of the box for pin damage or in the rack. If damaged, repair pin.
3. Interchange SECU 1 with SECU 2. If problem follows, replace SECU 1.
   NOTE: Perform electronic rigging of both SECUs when either SECU is swapped or replaced. The intent is if a SECU that is being installed was previously rigged in a different location in the same aircraft or it is being installed in a different aircraft or the SECU is a spare part it requires electronic rigging (AMM 27-61-05-820-802) per the instructions in AMM TASK 27-61-05-400-801 Installation of the Spoiler Electronic-Control Unit (SECU).
4. Check wiring from FSCL RVDT 1 to SECU 1. If damaged, repair wiring.
5. Check Flight Spoiler Control Lever (FSCL) RVDT 1 coil resistance.

   1. Remove SECU 1 and locate connector A118AP1.
   2. Pin 2A to 1E = 91 Ω ±5%.
   3. Pin 2B to 1E = 91 Ω ±5%.
   4. Pin 7B to 7A = 197 Ω ±5%.
   5. If coil resistances are out of tolerance, then replace FSCL.

6. Perform close out.
