This AD is cancelled on 3 July 2008.
Background:	This Directive specified once-only modification of a cabin heater box plate in 1961 in accordance with Piper SB No. 203.  This Directive was not based on a USA Directive.  As all affected aircraft would have been modified long ago, this AD is no longer required.
