### TITLE: AIR CONDITIONING - CABIN PRESSURE CONTROL SYSTEMINSPECTION-SAFETY VALVE DESIGN LIFE EXCEEDANCE **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES The Cabin Pressure Control System (CPCS) safety valves, installed on the aft pressure bulkhead, are parts of the pressure control and monitoring system. They prevent too much positive or negative differential pressure in the fuselage. The service life of the safety valve with Part Number (PN) 7012-18088 and 7012-18088-03 is limited to 50.000 Flight Hours (FH) or 12 years. This Inspection Service Bulletin details the work required to identify the safety valves having exceeded the service life limits. This Service Bulletin is also issued to advise all operators of A330-200/300 aircraft of the issue of Nord-Micro Service Bulletin No.18088-21-002. This Inspection Service Bulletin will identify valves having exceeded 50.000 FH or 12 years in order to ensure application of the restoration task to extend the service life to additional 50.000 FH or 12 years or to ensure replacement of safety valves by serviceable safety valves. Furthermore, the reliability of the pressure control and monitoring system will be increased. Accomplishment of A330 Maintenance Review Board Report MRBR task 21.31.00/09 constitutes compliance with requirements of this Service Bulletin.

(5) Configuration definition **CONF 002 Config. 002 is valid for all aircraft given in the effectivity of this inspection Service Bulletin which have two safety valves installed. **CONF 001 Config. 001 is valid for all aircraft given in the effectivity of this inspection Service Bulletin which have three safety valves installed. (6) Material Effectivity No Material Set B. CONCURRENT REQUIREMENTS None C. REASON (1) History The Cabin Pressure Control System (CPCS) safety valves, installed on the aft pressure bulkhead, are parts of the pressure control and monitoring system. They prevent too much positive or negative differential pressure in the fuselage. The service life of the safety valve with Part Number (PN) 7012-18088 and 7012-18088-03 is limited to 50.000 Flight Hours (FH) or 12 years.

# @A330 SERVICE BULLETIN (2) Objective/Action This Inspection Service Bulletin details the work required to identify the safety valves having exceeded the service life limits. This Service Bulletin is also issued to advise all operators of A330-200/300 aircraft of the issue of Nord-Micro Service Bulletin No.18088-21-002. (3) Advantages This Inspection Service Bulletin will identify valves having exceeded 50.000 FH or 12 years in order to ensure application of the restoration task to extend the service life to additional 50.000 FH or 12 years or to ensure replacement of safety valves by serviceable safety valves. Furthermore, the reliability of the pressure control and monitoring system will be increased. (4) Operational/Maintenance Consequences Accomplishment of A330 Maintenance Review Board Report MRBR task 21.31.00/09 constitutes compliance with requirements of this Service Bulletin. D. DESCRIPTION To accomplish this Service Bulletin it is necessary to : **CONF 001 Task 213154-832-848-001: Inspection (1) Inspect the safety valves 316HL, 317HL and 318HL (2) Restoration of safety valve **CONF 002 Task 213154-832-848-001: Inspection (1) Inspection the safety valves 316HL, 317HL (2) Restoration of safety valve **CONF ALL E. COMPLIANCE (1) Classification MANDATORY: Service Bulletin must be accomplished.

# @A330 SERVICE BULLETIN (2) Accomplishment Timescale This Service Bulletin has been classified Mandatory. It is expected that an Airworthiness Directive (AD) published by the European Aviation Safety Agency (EASA) will be issued to confirm this classification. It is anticipated that the AD will confirm the (thresholds and/or intervals and/or date) given below but reference should be made to the AD for confirmation of the mandated accomplishment timescale. Table 1, Config. All - General visual inspection of installed CPCS safety valve Condition Action Compliance time All aircraft Check the approved maintenance records to determine the safety valve accumulated Flight Hours (FH) and years from first installation on an aircraft. None

The number of Flight Hours (FH) accumulated by the installed CPCS safety valve can be positively established. Replace the CPCS safety valve with a CPCS serviceable safety valve. Whichever occurs later between a) and b) a) before the safety valve has accumulated 50.000 Flight Hours (FH) or 12 years since manufacture or 12 years since last restoration according to VSB 18088-21-002, whichever occurs first or b) within 26 months after the Service Bulletin issue date. The number of Flight Hours (FH) accumulated by the CPCS safety valve cannot be positively established. Replace the CPCS safety valve with a CPCS serviceable safety valve. Within 26 months after the Service Bulletin issue date. CPCS Safety valve is replaced. Complete and send the report sheet to AIRBUS. Within 3 month after the replacement. Definition for a serviceable CPCS safety valve: A serviceable CPCS safety valve is a safety valve which has accumulated less than 50.000 Flight Hours (FH) and not older than 12 years since manufacture or since last restoration according to VSB 18088-21-002. F. APPROVAL The technical content of this document is approved under the authority of Design Organisation Approval No. EASA.21J.031. If an aircraft listed in the effectivity has a modification or repair embodied that is not of AIRBUS origin, and which affects the content of this Service Bulletin, the operator is responsible for obtaining approval by its airworthiness authority for any adaptation necessary before incorporation of the Service Bulletin.
