of the United States chairman of the National Transportation Safety Board (NTSB). By Jennifer Homendy according to the report, it is still not possible to say what the cause of the plane crash is.
The NTSB has asked the public for help in searching for a piece of the wall. According to Homendy, the piece fell over Cedar Hills, a suburb of Portland, and is likely to be found in the same area.
The piece of the cabin wall in question came off during the plane's flight on Friday. The plane had time to be in the air for more than half an hour before it made an emergency landing back at the airport.
The plane's pressure drop was so strong that it blew open the cockpit door, according to Reuters.
No one was seriously injured.
Also more information has been obtained about the machine's sound recordings.
According to Homedy, it was not possible to listen to the audio recording of the plane's cockpit. The voice recorder can record for two hours at a time, after which the recording starts over. The new recording is recorded over the previous recording.
When the maintenance team received the audio recording of the flight, the recording from the time of the crash had already been replaced with a new one.
“If [ohaamon] the speech has not been recorded, it is an unfortunate loss for us, the FAA and safety because that information is crucial. Not only for our research, but also for improving flight safety,” said Homendy.
The NTSB has sought to extend the cockpit voice recording requirement to 25 hours, Homendy said. He noted that in November, the FAA proposed a rule that would increase the number of hours of recording. The rule would only apply to newer machines.
Federal The Federal Aviation Administration (FAA) ordered on Saturday that 171 Boeing planes must remain on the ground until they are deemed safe.
About 170 planes all have the same piece of wall as the plane that made the emergency landing, Reuters reports.
