Background:
Investigation into an incident involving an A320 aircraft showed that seizure of the alternate brake valve distribution body (BDDV) had been caused by water ingress into the valve.  The measures introduced by the initial issue of this Directive provides inspection and operational tests to prevent a dormant in-flight failure of the alternate braking system pending the release of a permanent modification.
Amendment 1, effective 15 June 2000, was raised to provide terminating action for this Airworthiness Directive.
This amendment is raised to correct the AD reference in the note.  DGAC AD
1998-262-120(B) R4 dated 8 September 1999 has been superseded by DGAC AD
2000-258-146(B) dated 14 June 2000.
There is no technical change to the requirements (beyond specifying a terminating action for Requirement 1) and no change to the compliance from the previous amendment.  Compliance with the previous amendment of this AD constitutes compliance with this amendment.
Exclusions granted to Amendment 1 of this AD remain valid against this amendment.
Amendment 1 of the Airworthiness Directive became effective on 15 June 2000.
The original issue of this Airworthiness Directive became effective on 22 April 1999.
