![]() “We have asked for permission from the NTSB to address these questions – they will not permit us to comment at this time,” the airline said. “That information is key not just for our investigation, but for improving aviation safety.”Īsked for comment about the overwritten CVR and other aspects of the incident, Alaska Airlines told CNN it was unable to comment, saying it would need permission from the NTSB. “That is unfortunately a loss for us, and a loss for FAA and a loss for safety,” Homendy said. “The circuit breaker for the CVR was not pulled. The maintenance team went out to get it, but it was right at about the two-hour mark.” “There was a lot going on, on the flight deck and on the plane. National Transportation Safety Board Chair Jennifer Homendy speaks to the media about the investigation of Alaska Airlines flight 1282 in Portland, Ore., Saturday, Jan. ![]() A mechanic or pilot can cut off power to the recorder, preserving it as a time capsule that later can be downloaded at a specialized laboratory, such as at the NTSB’s Washington lab or the French Bureau d’Enquêtes et d’Analyses.Īlaska Airlines tried to do that in this case, Homendy suggested in the news conference. After the plane landed in Portland, airline officials were busy setting up their emergency operations center. They eventually sent a mechanic to look into the voice recorder. ![]() There is a process for freezing the recording and preventing further overwriting. Often you can hear what’s happening with the door that blew open, headsets that might have flown off,” she said. You can hear what’s happening with the engines. “It’s not just about communication – it’s about everything else. “When we have the CVR, we kind of match up the timeline with everything that was occurring in the cockpit,” Homendy told CNN’s Pete Muntean, adding investigators are “able to isolate the smallest sounds” to help shed light on an incident. “You can easily install a different cockpit voice recorder and increase the time from two hours to 25 hours,” she said Sunday night.ĬVRs are a crucial tool in investigators’ efforts to shed light on an incident like the one that unfolded Friday above Portland, Oregon. ![]() The FAA last year proposed requiring 25 hours of recording for cockpit voice recorders. But it would only apply to newly-manufactured planes, Homendy noted, adding she wants the FAA to change its proposal and require aircraft currently flying to be retrofitted. She is calling on the Federal Aviation Administration to require a 25-hour recording window for the cockpit voice recorder in all aircraft – a duration that is already a standard requirement under European airline regulations. Now, Homendy wants the recording standard to change. It is an anomaly in the era of inexpensive and expansive digital storage, when the phone of each passenger onboard a flight could easily have more capacity than the plane’s voice recorder. “Cockpit voice recorders aren’t just convenient … they are critical to helping us accurately pinpoint what was going on,” she said in a news conference Sunday night. Missing part of Alaska Airlines plane is found in Portland, Oregon, NTSB says, as new details emerge about the aircraft National Transportation Safety Board officials retrieve the missing door plug from Alaska Airlines flight 1282, the Boeing 737 MAX 9 that experienced a rapid decompression on Friday over Portland, Oregon. ![]()
