Airlines grounded dozens of older Boeing 777 aircraft after the failure of a Pratt & Whitney engine showered debris into a Denver suburb and prompted US regulators to order emergency inspections.
United Airlines halted operations of 24 of its planes in the wake of the incident involving one of its fleet over the weekend, after the US Federal Aviation Administration ordered fan-blade checks on PW4077 engines. Japan’s transport ministry grounded planes with the engine variant on Monday, while Korean Air Lines and Asiana Airlines idled theirs.
