A specific engine part must now be replaced sooner than airlines expected
What happened
US aviation regulators propose a new rule for General Electric CT7-2E1 aircraft engines. Airlines will have to replace a specific turbine part earlier than they do now.
Why it matters
Airlines will face higher maintenance costs for these engines. This change comes from a new stress model that found the part wears out faster than previously calculated. It means the safety margin for these engines just got smaller.
The signal
Watch for airlines to update their maintenance schedules and potentially increase ticket prices on routes using aircraft with these engines.
