AD FAA-2006-25896

The FAA is superseding an existing airworthiness directive (AD) for GE CF34-10E series turbofan engines. That AD currently requires removing the fuel inlet strainer from main fuel pump (MFP) part number (P/N) 2043M12P03, installing a certain replacement flange as an interim repair, remarking the MFP to P/N 2043M12P04, and performing initial and repetitive visual inspections of the main fuel filter. This AD requires removing MFPs, P/Ns 2043M12P03, 2043M12P04, 837600-3, and 837600-4, from service and installing an improved MFP with a different P/N. This AD results from GE determining that the cause of MFP fuel strainer failure is a design problem with the strainer. We are issuing this AD to prevent engine in-flight shutdown due to MFP malfunctions.
