Rolls-Royce jet engines get a permanent fix for a known crack problem

The US aviation regulator is replacing a rule that required repeated inspections of certain Rolls-Royce jet engines. Instead of inspections, airlines must now install a redesigned part that fixes the problem permanently. This means fewer maintenance checks for airlines and a safer engine design overall.

For years, airlines had to repeatedly check for cracks in a specific part of some Rolls-Royce engines. This was a known issue that required ongoing maintenance. Now, the problem is solved with a new part, which means less downtime for planes and lower operating costs for airlines. This kind of permanent fix, replacing a recurring inspection, is a small but significant shift in how regulators address known safety issues.
