FAA proposes changes to inspection rules for Rolls-Royce Trent 7000 engines

The Federal Aviation Administration is proposing a new Airworthiness Directive (AD) that would replace the current rule for Rolls-Royce Deutschland Model Trent 7000-72 and Trent 7000-72C engines. The current rule, issued in 2022, requires airlines to perform specific borescope inspections of the high-pressure turbine blades to look for cracks and sets a reduced life limit on those parts.

Why it matters: This is a technical update to an existing safety rule. It does not change the fact that inspections are required, but it removes an artificial lifespan restriction on the parts. For operators, this means they may be able to keep using the blades longer than the 2022 rule allowed, provided they pass the required inspections. It is a routine administrative adjustment to match current engineering data.

Who it affects

• Airlines operating aircraft equipped with Rolls-Royce Trent 7000-72 or Trent 7000-72C engines
