The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) Model CF34-10E2A1, CF34-10E6, CF34-10E6A1, CF34-10E7, and CF34-10E7-B engines having certain high- pressure turbine (HPT) front rotating air seals installed. This proposed AD was prompted by a report of cracks found in the HPT front rotating air seal. This proposed AD would require performing repetitive fluorescent penetrant inspections (FPIs) to detect indications or linear indications (any indication which is four times longer than the width of that same indication) in the HPT front rotating air seal and, if necessary, replacement of the HPT front rotating air seal or HPT rotor disk with parts eligible for installation as applicable. This proposed AD also includes an optional terminating action to the repetitive FPIs. The FAA is proposing this AD to address the unsafe condition on these products.
