### 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 A340-200/300 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 A340 MRBR task 21.31.00/09 constitutes compliance with requirements of this Service Bulletin.

# @A340 SERVICE BULLETIN (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. (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 A340-200/300 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.

Table 1, Config. All - General visual inspection of installed CPCS safety valve Condition Action Compliance time Definition for a CPCS serviceable 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. G. MANPOWER The manpower estimates given in this Service Bulletin are based on the direct labor cost to do the work. These estimates assume that the work will be done by experienced personnel, and may need to be revised upwards to suit operator’s circumstances. The estimates do not include the time to prepare, plan or inspect the work.
