Unsafe Condition

Due to a misbehaviour in the establishment of the FWS logic, it is possible that the AIR Auxiliary Power Unit (APU) BLEED LEAK Electronic Centralized Aircraft Monitoring (ECAM) alert triggers several times. This condition, if not corrected, could lead to exposure of critical locations and surrounding structure to heat stress, possibly resulting in reduced structural integrity of the aeroplane.
