Mandatory inspections for GE CF34 engines
If you operate aircraft with GE Model CF34-10E2A1, CF34-10E6, CF34-10E6A1, CF34-10E7, CF34-10E7-B, CF34-10E5, or CF34-10E5A1 engines, the FAA now requires repetitive fluorescent penetrant inspections (FPIs) of the high-pressure turbine (HPT) front rotating air seal to find cracks or 'linear indications' (any indication four times longer than its width). If an inspection finds an indication, you must replace the HPT front rotating air seal or the HPT rotor disk with parts eligible for installation as applicable. The AD also includes an optional terminating action that ends the repetitive FPI requirement when taken.
