Pratt & Whitney jet engine bolts are cracking, requiring new inspections

The US aviation regulator proposes new rules for certain Pratt & Whitney Canada jet engines. This means airlines must regularly inspect specific bolts on these engines for cracks and replace them if needed.

Airlines operating aircraft with these engines now face mandatory, repetitive inspections. This adds to their operational costs and maintenance schedules. The change comes from a manufacturer's own review, showing that a known part is failing faster than expected.
