REPLACEMENT OF FLIGHT CONTROL REMOTE MODULE (FCRM)
SUMMARY This summary is for information only and is not approved for modification of the aircraft.
A. MODIFICATIONS
MODIFICATION CLASSIFICATION MAJOR None MINOR None NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics affecting the airworthiness of the product. All other changes are major changes.
B. REASON
(1) History A350 operators experienced several cases of flight control actuator failures solved by Flight Control Remote Module (FCRM) replacement. A statistical analysis has demonstrated that the FCRM failure rate increases with increased Flight Cycles (FC) and/or Flight Hours (FH).
The safety analysis concludes that the FCRMs have to be replaced before reaching 9000 FC or 50000 FH, whichever occurs first.
(2) Objective/Action The objective of this Service Bulletin (SB) is to give instructions to operators to review the maintenance records with the objective of checking FCRM Part Number (PN) and Serial Number (SN) and corresponding FC and FH.
(3) Advantages The accomplishment of this Inspection Service Bulletin (ISB) will enable the planning for replacing in a timely manner the concerned FCRM and ensure the continuous airworthiness of the Aircraft (A/C).
(4) Operational/Maintenance Consequences None C. GENERAL EVALUATION
