SLAT ACTUATION SYSTEM NOT RIGGED #1
Fault Code:
2751042STD

Fault Description:
Rigging of the Slat System is incorrect. Data from the Data Acquisition Units (DAUs) does not compare with the data stored in the Slat/Flap Control Unit (SFCU) non-volatile memory for the below conditions:
- Out of tolerance rigging data
- Dates that do not agree
- Aircraft serial numbers that do not agree
Possible Causes:
- Slat/Flap Control Unit (SFCU) 1 (A124)
- Slat/Flap Control Unit (SFCU) 2 (A95)
- Associated Wiring
Troubleshooting Tips:
Advisory Wire/Service Bulletin: None
Forum Articles/Infoservice/Newsletter: None
This fault is normal if both SFCUs have never been installed on the A/C.
This fault is normal if an IAC was replaced and the A/C identification in CAIMS is not same as the A/C. The fault should clear after performing the installation procedure of the IAC.

Troubleshooting Recommendations:
- Confirm the A/C identification (SN of aircraft) time & date are good and agree for each of the three IACs.
- If all data are good and agree, continue with next step.
- If data does not agree, adjust and set the three IACs.
- To access the aircraft ID:
Aircraft Identification (ID) Mode Make this selection Result START AIRCRAFT DIAGNOSTICS DEFINE AIRCRAFT ID The AIRCRAFT ID menu shows Use the up/dn arrows as necessary to increase or decrease the aircraft ID numbers APPLY Writes the new aircraft ID number into the NVM of the IACs CANCEL Cancels the menu - If both SFCUs are reporting that the slats and flaps are rigged, continue with next step.
- If both SFCUs are reporting that the slats and flaps are not rigged, perform a complete rigging of the slats and flaps for SFCU installation.
- If system checks are good, do close out.
- If fault remains, continue with next step.
NOTE: It is very important to perform the electrical rigging on the SFCU that is not reporting the fault because this will confirm the cross talk communication busses integrity.
- Perform wiring checks between SFCU 1 and 2 rack connectors (cross talk communication busses) as follow:
From To Result A124AP1-60 A95AP1-61 A124AP1-73 A95AP1-74 A124AP1-61 A95AP1-60 A124AP1-74 A95AP1-73 - If wiring checks are not good, repair defective wiring as required and do close out.
- If wiring checks are good, continue with next step.
- Replace the defective SFCU and perform slat electrical rigging on the SFCU that was not reporting the fault.
- Do close out.
