. Reason: Investigation results on the Cabin Pressure Control System (CPCS) safety valve demonstrate that this part is subject to repetitive restoration every 50 000 f light h ours (FH) or 12 years, but this airworthiness instruction is not yet reflected in the instructions for continuing airworthiness. Moreover, this safety valve, part of the CPCS, is not failure monitored. In order to maintain the required safety objectives, the CPCS safety valves must be replaced by a serviceable part no later than the above values. For the reasons described above, this AD requires repetitive replacement of CPCS safety valves.
