The cockpit voice recorder data on the Alaska Airlines Boeing 737 MAX 9 jet which lost a panel mid-flight on Friday was overwritten, U.S. 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 U.S. requires cockpit voice recorders to log two hours of data versus 25 hours in Europe for planes made after 2021.

The International Civil Aviation Organization (ICAO) has since 2016 called for 25-hour recording on planes manufactured from 2021.

“There was a lot going on, on the flight deck and on the plane. It’s a very chaotic event. The circuit breaker for the CVR (cockpit voice recorder) was not pulled. The maintenance team went out to get it, but it was right at about the two-hour mark,” Homendy said.

The NTSB has been vocal in calling for the U.S. to extend its rule to 25 hours. The U.S. Federal Aviation Administration (FAA) a month ago said it was proposing to extend to 25 hours – but only for new aircraft.

    Until their Air Force One, or any of their other defense products start being produced the way they produce aircraft that the general public uses, we will continue to be the guinea pigs to see how much regulation can be stripped away for profit margins until we start to die at rates that become unprofitable for them. Industry never really learned from the Triangle Shirtwaste Fire and safety regulations will continue to be written in blood because ALL legislators would rather take donations and shut up than challenge a component of the MIC.
