             This Amendment becomes effective on 29 September 2005.

Background:  The original issue of this Directive required a one- time inspection of the combustion heater fuel pumps for fuel leakage.  If leakage was found, repair or replacement of the fuel pump was undertaken.  This Directive retains all those actions and includes additional serial numbers for the Models PA-34-220T aeroplanes in the applicability section.  This Directive results from further investigation that concluded that additional fuel pumps that did not meet the quality control (inspection or design) requirements of the Directive had been installed in Models PA-34-220T and aeroplanes.  Quality control problems with the heater fuel pump could result in failure of the heater fuel pump.  Such failure could lead to fire or explosion in the cockpit.
