On the 22nd (local time), Boeing, the manufacturer, announced to AFP that all 128 Boeing 777 aircraft equipped with engines that recently malfunctioned during flight have been grounded.

On the 20th, after a Pratt & Whitney 'PW4000' engine on United Airlines Flight 328 from Denver to Hawaii failed during flight, Boeing advised airlines to suspend operations of the 777-200 and 777-300 models equipped with the same engine series until the U.S. aviation authorities complete their investigation procedures.

At the time of the engine failure, debris from the aircraft fell onto a residential area in broad daylight, but there were no casualties.

According to Boeing, a total of 128 Boeing 777 aircraft equipped with PW4000 series engines include 69 that have been in operation and 59 that had been grounded earlier due to decreased travel demand.

These aircraft are operated by United Airlines, Japan's Japan Airlines (JAL) and All Nippon Airways (ANA), South Korea's Korean Air and Asiana Airlines, and Jin Air.

Asiana Airlines announced on the afternoon of the same day that it had suspended operations of nine 777 aircraft equipped with PW4000 series engines (including two that were already grounded), and Korean Air is expected to announce its measures soon.

Korean Air owns 54 Boeing 777 aircraft, of which 16 are equipped with PW4000 series engines, and currently 10 of these are grounded.

Jin Air operates four Boeing 777-200ER aircraft equipped with PW4000 series engines and reportedly has no flight plans through the weekend.

United Airlines decided to suspend operations before Boeing's announcement, and Japan's Ministry of Land, Infrastructure, Transport and Tourism also ordered the suspension of 777 aircraft equipped with PW4000 series engines the previous day.

United Airlines was operating 24 Boeing 777 aircraft equipped with PW4000 series engines.

JAL and ANA own 13 and 19 aircraft respectively.
