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.

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.

(4) Operational/Maintenance Consequences

Accomplishment of A340 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 :
