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