FAA Orders Radio Fix On 787s

News Discussion

The FAA has ordered a $127.50 software upgrade for 157 Boeing 787s in the U.S. fleet to fix a potentially problematic glitch with their radios. Apparently, the radios will randomly toggle between active and standby frequencies without pilot input. "The uncommanded frequency changes could result in missed communications between the flight crew and Air Traffic Control," the agency said in an AD issued more than a month ago.

3000 hours 787. Never even heard of this happening. Keep in mind - Boeing doesn’t make radios or tuning control panels.

“This AD applies to The Boeing Company Model 787-8, 787-9, and 787-10 airplanes…”

Seems the comm panels are different across variants. Maybe it’s due to the technology leaps between the -3s era and the -8+ era. Interesting.
