General Electric Company CF34-10E Series Turbofan Engines
Superseded. A later AD replaced this one: AD 2007-12-15. Comply with the one in force.
This AD applies to General Electric Company (GE) CF34-10E2A1, -10E5, -10E5A1, -10E6, -10E6A1, and -10E7 turbofan engines. 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 adopting a new airworthiness directive (AD) for General Electric Company (GE) CF34-10E series turbofan engines. This AD requires removing the main fuel pump (MFP) inlet strainer from certain MFPs, installing a certain replacement flange as an interim repair, and performing initial and repetitive visual inspections of the main fuel filter. This AD results from three reports of release of the tripod support legs on the MFP inlet strainer, leading to engine in-flight shutdown. 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.
Within 40 engine flight hours after the effective date of this AD, remove the MFP inlet strainer from the affected MFPs listed by serial number in paragraph D. of GE Alert Service Bulletin (ASB) No. CF34-10E S/B 73-A0011, dated September 15, 2006.
(g) Within 150 engine flight hours after the effective date of this AD, remove all other MFP inlet strainers.
(h) Install a replacement flange, part number 837683, in all MFPs as an interim repair.
(i) Remark the MFP part number from 2043M12P03 to 2043M12P04.
(j) When performing the actions in paragraphs (f), (g), (h), and (i) of this AD, use paragraphs 3.A. through 3.E.(1)(c) of the Accomplishment Instructions of GE ASB No. CF34-10E S/B 73-A0011, dated September 15, 2006.
Perform an initial visual inspection of the main fuel filter at the time of MFP inlet strainer removal in paragraphs (f) and (g) of this AD.
(l) Perform repetitive visual inspections of the main fuel filter within every additional 160 engine flight hours.
(m) When performing main fuel filter visual inspections in paragraphs (k) and (l) of this AD, use paragraphs 3.F.(1) through 3.F.(6) of the Accomplishment Instructions of GE ASB No. CF34-10E S/B 73-A0011, dated September 15, 2006.
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.
