Jet engines wear out faster in South Asia, requiring more checks

The US aviation regulator is tightening safety checks for specific jet engines. Airlines must now inspect high-pressure turbine blades more often, especially for planes flying in South Asia, or replace them.

Jet engine parts wear out. This rule means airlines must now account for faster wear in a specific region. It will increase maintenance costs for some airlines, but it also means regulators are constantly updating safety based on real-world data.
