Planes with specific Rolls-Royce engines must remove cracking-prone blades

The US aviation regulator proposes that certain Rolls-Royce aircraft engines must replace specific low-pressure compressor blades. These blades were improperly repaired and are now prone to cracking.

Aviation safety relies on constant vigilance, even for parts that have already been repaired. This proposed rule means airlines must replace specific engine blades that were improperly fixed and could fail. It reminds everyone that even after a part goes through a repair process, it can still pose a risk if the repair itself was faulty.
