AIR DUAL BLEED FAULT
Note: In dual bleed failure, the rate at which the cabin altitude increases may be
minimized by closing
the forward cargo isolation valve, if the cargo freight permits.
�� ENG 1 BLEED failure :
This procedure is to be applied if ENG 1 BLEED was lost due to a :
‐ LEAK on side 1, or
‐ ENG 1 FIRE, or
‐ Start Air Valve 1 failed open.

�� ENG 2 BLEED failure :
This procedure is to be applied if ENG 2 BLEED was lost due to a :
‐ LEAK on side 2, or
‐ ENG 2 FIRE, or
‐ Start Air Valve 2 failed open.

Descend rapidly to FL 225, so that the bleed supply may be supplied by the APU, if
the bleed system
recovery is not successful.
�� If both packs are available :
If both packs are operative, it can be suspected that the second bleed system failed due
to
excessive demand. Recovery of the second failed engine bleed may be attempted.
