RATIONALE AMSAMSQQ428B has been declared Stabilized as it is no longer being used by industry. STABILIZATION NOTICE. AMSQQW428B has been declared "STABILIZED" by AMS Committee E. This document will no longer be updated and may no longer represent standard industry practice. This document was stabilized because this document is no longer state of the art and other documents contain similar but not necessarily equivalent requirements. Previously this document was reaffirmed non-current. The last technical update of this document occurred in December 1998. Users of this document should refer to the cognizant engineering organization for disposition of any issues with reports/certifications to this specification; including exceptions listed on the certification. NOTE: In many cases, the purchaser may represent a sub tier supplier and not the cognizant engineering organization. AMS Committee E recommends that the following similar but not identical specifications may be considered for future procurement.
