             The effective date of this Amendment is 10 September 2013.
Background:  Amendment 1 is issued to correct typographical error in Note 2 of the Requirement Section.  The FAA AD reference is corrected from 2000-03-35 to 2000-02-35.

             The Federal Aviation Administration has advised that Raytheon received reports indicating that a field survey revealed that a reaction process was occurring, which resulted in cadmium flaking.  The flaking could cause blocking of valves resulting in impairing the function of the oxygen system, which could deprive the crew and passengers of necessary oxygen during an emergency that requires oxygen.

             This Directive specifies actions designed to prevent flaking of cadmium from certain oxygen system plumbing fittings and cone caps from blocking the valves.

   There is no change to initial requirements of the AD.

   The original issue of this Airworthiness Directive became effective on
   23 March 2000.
