Airworthiness Directive · Amendment 39-15093 · General Electric Company (GE) CF34-10E Series Turbofan Engines
General Electric Company (GE) CF34-10E Series Turbofan Engines
This AD applies to General Electric Company (GE) CF34-10E2A1, -10E5, -10E5A1, -10E6, -10E6A1, and -10E7 turbofan engines, with main fuel pump (MFP) part number (P/N) 2043M12P03, P/N 2043M12P04, P/N 837600-3, and P/N 837600-4 installed. These engines are installed on, but not limited to, Embraer ERJ 190-100-STD, ERJ 190-100-LR, and ERJ 190-100-IGW airplanes.
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.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
Not later than July 31, 2007, remove MFPs, P/Ns 2043M12P03, 2043M12P04, 837600-3, and 837600-4 from service and install a serviceable MFP.
For the purpose of this AD, a serviceable MFP is one that does not have P/N 2043M12P03, 2043M12P04, 837600-3 or 837600-4.
We recommend that operators avoid performing the actions in this AD on both engines installed on the same airplane at the same time, if at all possible.
