Older Pratt & Whitney jet engines need new inspections after a different engine failed

The US aviation regulator wants new inspections for specific Pratt & Whitney jet engines. This is because a different engine model from another company had a part break during takeoff, which led to an aborted flight.

A single engine failure on one type of jet engine can trigger new inspection requirements for many other engine models. This means airlines and maintenance crews will have to add new checks to their schedules for a range of planes, even if those planes haven't had a similar problem. It shows how one incident can quickly ripple through the entire aviation industry, changing maintenance costs and operational procedures.
