Boeing 777 planes grounded by airlines in US and Japan after engine failure

Boeing Co said it recommended suspending the use of 777 jets with the same type of engine that shed debris over Denver at the weekend after U.S. regulators announced extra inspections and Japan suspended their use while considering further action.

Iran PressAmerica: The moves involving Pratt & Whitney 4000 engines came after a United Airlines 777 landed safely at Denver International Airport on Saturday local time after its right engine failed.

Boeing said 69 of the planes were in service and 59 were in storage, at a time when airlines have grounded planes due to a plunge in demand associated with the COVID-19 pandemic.

Images posted by police in Broomfield, Colorado showed significant plane debris on the ground, including an engine cowling scattered outside a home and what appeared to be other parts in a field.

The 777-200s and 777-300s affected are older and less fuel-efficient than newer models and most operators are phasing them out of their fleets.

Japan's transport ministry ordered Japan Airlines Co Ltd (JAL) and ANA Holdings Inc to suspend the use of 777s with P&W4000 engines while it considered whether to take additional measures.

A spokeswoman for South Korea's transport ministry, speaking before Boeing recommended suspending operations, said it was monitoring the situation but had not yet taken any action.

Korean Air Lines Co Ltd said it had 12 of the planes, half of them stored, and it would consult with the manufacturer and regulators and stop flying them to Japan for now.

In Feb. 2018, a 777 of the same age operated by United and bound for Honolulu suffered an engine failure when a cowling fell off about 30 minutes before the plane landed safely.
