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.
Ridiculous it hasn’t been updated
There’s a lot of laws or regulations that end up this way because nobody is required to do any periodic review.
There’s more than 30,000+ federal statutes alone. Not including agencies, standards boards, state laws, etc.
As great as that would be, I’m not sure it could be done. (Good use for ai? Read all the laws and spit out a list of obsolete laws or things that need review?)
The entire airline industry runs on antiquated tech.
Between new certifications being needed for everything, and an attitude of “if it ain’t broke, don’t fix it”, combined with the constant attempts to save money, airplanes are rarely updated.
