Some jet engines must replace specific rotor blades to prevent failure

The US aviation regulator proposes that certain jet engines must replace a specific part. This is because the manufacturer found that these parts can wear out and cause the engine to fail.

When a manufacturer finds a defect in an engine part, the US aviation regulator often issues a mandatory directive. This ensures that all affected aircraft are inspected and repaired, preventing potential accidents. This proposed rule means that airlines operating these specific engines will have to schedule maintenance and replace the blades.
