Alaska 737 cockpit voice recorder data erasure renews industry safety debate
Washington: The cockpit voice recorder data on the Alaska Airlines Boeing 737 MAX 9 jet which lost a panel mid-flight on Friday was overwritten, US authorities said, renewing attention on an industry call for longer in-flight recordings.
National Transportation Safety Board (NTSB) chair Jennifer Homendy said on Sunday no data was available on the cockpit voice recorder because it was not retrieved within two hours – when recording restarts, erasing previous data.
The US requires cockpit voice recorders to log two hours of data versus 25 hours in Europe for planes made after 2021.
