The Federal Aviation Administration (FAA) is proposing a new rule that would affect General Electric Model CT7-2E1 engines. This is due to a study that found the part known as the stage 2 turbine aft cooling plate may not last as long as previously thought. The proposed rule requires reducing the life limit for this part from 6,100 to 3,100 cycles to prevent possible engine failure, which could lead to airplane damage. The FAA is accepting comments on the proposal until January 21, 2025.
Simple Explanation
The FAA wants to make a new rule for airplane engines made by GE because a part inside might not last as long as they first thought. They suggest changing its safety rules so the part gets checked or replaced sooner, from 6,100 to 3,100 times it's used, to keep planes safe.
