    ICON has experienced several field service difficulty reports and numerous production line non-conformance reports of one or both of the fuel pumps in the Rotax fuel pump assembly that are failing to make rated pressure. The failures are associated with Rotax Fuel Pump Assembly Part Number 889696 Serial Numbers 18.XXXX and 19.XXXX series of fuel pump assemblies. The pump assembly failures are typically characterized by one or both fuel pumps in the assembly failing to make rated fuel pressure of 43.5 ± 3.0 PSI (3.0 ± 0.2 bar). This is indicated to the operator by a FUEL PRESS light or FUEL PRESS / LAND AIRCRAFT light being displayed on the annunciator panel while the engine is running, or if a FUEL PRESS caution is displayed after 6 seconds with just the pumps running. Field failures were identified by their respective operator without incident. All production line failures were identified and fuel pumps replaced prior to aircraft completion and delivery. To ICON Aircraft’s best information, the pumps in the affected series will only be found in Aircraft Serial Numbers 00087 and beyond. Out of an abundance of caution ICON has applied this Safety Directive/Alert to all aircraft. ICON Aircraft is working closely with Rotax to come to a timely resolution of this issue. To increase the opportunity for the operator to identify a faulty pump prior to flight, ICON Aircraft requires that the following instructions are complied with prior to next flight.
