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.
We must receive any comments on this proposed AD by March 19, 2007.
We invite you to send any written relevant data, views, or arguments regarding this proposal. Include "Docket No. FAA-2006-25896; Directorate Identifier 2006-NE-33-AD'' in the subject line of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the proposed AD. We will consider all comments received by the closing date and may amend the proposed AD in light of those comments.
