February 22 – A few days ago, a United Airlines Boeing 777 plane flying to Honolulu dropped debris while flying during the emergency return period.
On the 21st, United Airlines announced that it would temporarily suspend all 24 Boeing 777 passenger planes with the same engine. The Federal Aviation Administration (FAA) said it would strengthen testing of the Boeing 777, while Japan said it would suspend its use.
According to previous reports, on February 20th local time, a United Airlines flight to Honolulu was forced to return to Denver International Airport due to engine failure shortly after takeoff. And in the process of returning, the debris begins to fall.
In several residential areas near the airport, fragments of aircraft engines have been found. Some residents said they heard loud noises and saw black smoke in the sky.
According to Fox News, the Federal Aviation Administration (FAA) said it would require the strengthening of testing of Boeing 777 aircraft equipped with Pratt & Whitney PW4000 engines.
“This could mean some aircraft will be out of service,” said FAA Director Dixon in a statement.
On February 20, local time, a United Airlines flight to Honolulu was forced to return to Denver International Airport due to engine failure shortly after takeoff. There were 241 people on the flight, including 10 crew members.
The picture shows thick smoke constantly coming out of the passenger engine.
United Airlines said it would continue to discuss with the competent authorities of the United States to decide whether any further measures are needed to “ensure that these aircraft meet our strict safety standards and can resume service”.
According to FAA officials, only the United States, South Korea and Japan currently use Boeing 777 aircraft equipped with Pratt & Whitney PW4000 engines, while United Airlines in the United States only use these aircraft.
In Japan, All Nippon Airways (ANA) has 19 aircraft of the same type and JAL has 13.
At present, the Ministry of Transport of Japan has ordered Japan Airlines and All Nippon Airways to stop using Boeing 777 passenger planes 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 taking off from Naha Airport in Okinawa Prefecture, a Japanese Airlines passenger plane urgently turned back and forced to land at the original airport due to the departure of the left engine.
This passenger plane is 26 years old like the Boeing 777 passenger plane that happened recently.
According to Reuters, Pratt & Whitney, a subsidiary of Raytheon Technologies Corp, has not commented on it so far.
Boeing said that the company’s technical advisers are supporting the National Transportation Safety Board.
