Flight Operation Notifications Manual (FONM): None

Brake Control System (BCS) NFF Action:

  • To support the technical investigation, FSRs and Service Centers are requested to perform an NVM download, complete a condition report and fill out this BCS questionnaire

NOTES:

  • Download and complete this Water Ingress Survey Form when complying with AW700-32-0573.
  • To avoid unnecessary replacement of BCS part due to Brake related CAS nuisance message, before troubleshooting, follow AW700-32-0513 instructions

    1. Proceed to a QAR (if available) download of the last three flights (Aircraft meeting FAR part 135.172.), SB700-31-020
    2. BCU NVM download
    3. IAC CAS messages download
