Airlines must inspect new jet engines for cracks after two in-flight failures

The US aviation regulator is ordering airlines to regularly inspect certain new jet engines for cracks. This means airlines will have to ground planes more often for checks or replace parts sooner than expected.

Two in-flight engine shutdowns on new planes are a serious problem. This order means airlines will now have to spend more money on maintenance and potentially replace parts on these engines much earlier in their lifespan. It also means the manufacturer, CFM International, will likely face higher warranty costs and a hit to its reputation for these newer engine models.
