China News Service, February 22, reported that a few days ago, a United Airlines Boeing 777 flying to Honolulu dropped debris while flying back during the emergency return.
On the 21st, United Airlines announced that it will temporarily ground all 24 of its Boeing 777 airliners with the same engine.
The US Federal Aviation Administration (FAA) said that it will strengthen testing of Boeing 777, while Japan said it will suspend its use.
According to previous reports, on February 20 local time, a United Airlines flight to Honolulu was forced to return to Denver International Airport due to an engine failure shortly after takeoff.
And in the process of returning, the fragments began to fall.
In several residential areas near the airport, debris from the aircraft's engine was found.
Some residents said they heard loud noises and saw black smoke in the sky.
According to Fox News, the Federal Aviation Administration (FAA) stated that it will require enhanced testing of Boeing 777 aircraft equipped with Pratt & Whitney PW4000 engines.
FAA Director Dixon said in a statement: "This may mean that some aircraft will be deactivated."
On February 20, local time, a United Airlines flight to Honolulu was forced to return to Denver International Airport due to an engine failure shortly after takeoff.
There are 241 people on the flight, including 10 crew members.
The picture shows thick smoke constantly emerging from the passenger plane engine.
United Airlines stated that it will continue to discuss with the U.S. authorities to determine whether any further measures are required to "ensure that these aircraft meet our strict safety standards and can resume duty."
According to FAA officials, only the United States, South Korea and Japan currently use Boeing 777 passenger aircraft equipped with Pratt & Whitney PW4000 engines, while only United Airlines in the United States uses these aircraft.
On February 21, local time, in a residential area near Broomfield on the outskirts of Denver, Colorado, debris falling from a United Airlines aircraft engine was found.
In Japan, All Nippon Airways (ANA) has 19 aircraft of the same type and Japan Airlines (JAL) has 13 aircraft.
Currently, Japan’s Ministry of Transport has ordered Japan Airlines and All Nippon Airways to suspend Boeing 777 aircraft equipped with Pratt & Whitney PW4000 engines, while considering whether to take additional measures.
The Ministry of Transport of Japan said that on December 4, 2020, after a JAL passenger plane took off from Naha Airport in Okinawa Prefecture, due to the failure of the left engine, it made an emergency return to the original airport.
This airliner has the same age of 26 years as the Boeing 777 airliner that crashed recently.
According to Reuters, Pratt & Whitney, a subsidiary of Raytheon Technologies Corp, has not yet commented on this. Boeing said the company's technical advisers are supporting the National Transportation Safety Board.
