Required Cooling Plate Replacements — GE CT7
If you own or operate aircraft with the listed GE Model CT7 engines (CT7-5A2, CT7-5A3, CT7-7A, CT7-7A1, CT7-9B, CT7-9B1, CT7-9B2, CT7-9C, CT7-9C3, CT7-9D, or CT7-9D2), the FAA requires you to replace the stage 1 turbine forward cooling plate and the stage 2 turbine aft cooling plate. The rule was issued because some fleets have cooling plates that do not meet lifing guidelines and the replacement is needed to address an unsafe condition.
