SPOILERS FAULT
(Advisory)

There is a fault in the spoiler system that does not affect spoiler operation.

Inhibited by the EICAS during take-off and landing conditions. Also inhibited when any of the 'SPOILERS FAIL' (amber), 'SPOILERS FAULT' (amber), 'ROLL SPOILERS FAIL' (amber), 'ROLL SPOILERS FAULT' (amber), 'FLT SPOILERS FAIL' (amber), 'FLT SPOILERS FAULT' (amber) 'GND SPOILERS FAIL' (amber) messages are displayed.

• Throttle Quadrant Assembly (TQA) - (A51)
• Control Wheel Resolver - (MT125, MT126)
• Flight Spoiler Control Lever (FSCL) Rotary Variable Displacement Transducer (RVDT) - (A6)
• Brake Control Unit (BCU) (A67)
• Input Output Concentrator (IOC) input bus or label
• Associated Wiring

NOTES :

• Selecting the roll disconnect on the ground and moving the control wheel separately will result in the message being posted. If this occurs, removing all power from the aircraft and re-powering will cause the message to clear.
• CAS Messages 'FLAPS FAULT' (cyan), 'STAB TRIM FAULT' (cyan) and 'SPOILERS FAULT' (cyan) all posted at the same time: Switch to Flight Control synoptic page and check for any abnormal indications.
• If either the left side flap indication is magenta dashes or the right side is magenta dashes, the flaps will work normally and on touchdown the EICAS messages will change to an 'FLAPS FAIL' (amber). Flaps will reset with Rotary flaps reset or cycling Pilot's CBs B13 (L IND) or B12 (R IND).
• CAS Messages 'FLAPS FAULT' (cyan), 'BRAKE FAULT' (cyan) and 'SPOILERS FAULT' (cyan) all posted at the same time: Switch to Hydraulic synoptic page and check for any abnormal indications.
• Look for the left hydraulic system indications to be magenta dashes. Additional troubleshooting on this condition, refer to advisory wire AW300-29-0079.
• The Spoiler Electronic Control Units (SECUs) can detect a nuisance fault during aircraft power-up in the ailerons are not in the neutral position. Refer to AW300-27-0086. This can be verified by putting on hydraulics and looking at the spoiler synoptic page, typically the outboard spoiler the yoke is tilted towards will go amber after their self-test.
• The B3-006879 LH, or B3-006880 RH fault equation will be posted.
• Center the yoke, re-power up the aircraft.
•  If CAS messages SPOILERS FAULT (Caution), SPOILERS FAULT (Advisory) and STAB TRIM FAULT (Advisory) are all displayed at the same time on the EICAS momentarily for few seconds (between 3 to 20 seconds) and possibly MDC messages B3-007899 - XTALK ARINC BUS [SPOILER ECU 1] or B3-007932 - XTALK ARINC BUS [SPOILER ECU 2], B3-007882 - NO L-SECU-1 BUS TO DCU [SPOILER ECU 1], B3-007915 - NO R-SECU-1 BUS TO DCU [SPOILER ECU 2] and B3-007969 - INVALID SECU INPUT [STALL COMPUTER] displayed together in the fault message history at the time of failure, download and send both SECU NVM files to the Bombardier Customer Response Center (CRC) for analysis.
• A metallic or reflective surface (Water, Ice, metal plates, metal grills, etc...) underneath the RA antennas when aircraft is on the ground can cause erratic readings and cause the unit to fail. The first thing that should be attempted is move the A/C a few feet and test the system again.
• If all or any combination of the following CAS are posted at the same time Troubleshoot the PROX SYS Fault (Advisory) first.
  PROX SYS FAULT (ADVISORY)
  STAB TRIM FAULT (ADVISORY)
  SPOILERS FAULT (ADVISORY)
  L ENGINE FAULT (ADVISORY)
  R ENGINE FAULT (ADVISORY)
  
  

1. If you experience a SPOILERS FAULT - Amber or Cyan EICAS message, combined with a B3-007883 and/or B3-007916 MDC fault in the CURRENT FAULTS and/or FAULT HISTORY, in order to prevent an unnecessary removal, ask the crew to perform MDC and SECU NVM download. The NVM download may be sent to the Bombardier Customer Response Center (CRC) for review.

   1. Look if the fault was triggered by "LTQAIdSwID" or "RTQAIdSwID" in the SECU NVM. If this is the case, replacing the TQA will fix the issue.
   2. Look if the fault was triggered by a "FrameOvrRun". If this is the case, the SECU may need replacement.

2. The SECUs have detected a fault that affects the redundancy of the SCS. The definition of these signals would include such failures as the following:

   • Failure of a Control Wheel Resolver
   • Failure of an FSCL RVDT
   • Failure of an IOC input bus or label

3. Retrieve from MDC faults associated to the spoiler system, either nomenclature, or Equation ID #.
