Reason:

The modification (MOD) 58723 (A340-200/300) and the MOD 58724 (A340-500/600) consist in 

installing on A340 a Flammability Reduction System (FRS) to reduce the oxygen concentration in 

the centre fuel tank by feeding it with Nitrogen-Enriched Air (NEA).

The aim of this variation is to introduce a Critical Design Configuration Control Limitation (CDCCL), 

related to the design changes having an effect on FRS performance and/or an effect on fuel tank 

flammability exposure. This CDCCL applies to FAA operators only.

Any design change that could reduce the bleed pressure in descent or could add any heat to the centre wing tank or could increase the heat retention of the centre wing tank is not allowed without an FAA approved analysis to show that the change does not affect the FRS performance per the requirements of Appendix M to 14 CFR Part 25, Amendment 125.
