## Summary

The FAA proposes to supersede an existing airworthiness directive (AD) for General Electric Company (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 proposed AD would require removing MFPs, P/N 2043M12P03 and 2043M12P04 from service and installing an improved MFP with a different P/N. This proposed AD results from GE determining that the cause of MFP fuel strainer failure is a design problem with the strainer. We are proposing this AD to prevent engine in-flight shutdown due to MFP malfunctions.
