I highly doubt it. Perhaps, however, the pilots contacted the company, and the phone call was directed to UAL’s Newark Operation Team. If that was the case, chances are there was a hot mic involved, too, which would make sense with all the static heard on the ATC archive (the radio appeared clear for all aircraft).
Where’d you hear this from?
The reason for the diversion was due to a RA (Resolution Advisory). I don’t know the details about it and what led to the need for a diversion, but there was no compressor stall. Not to mention, the flight departed for EWR within an hour of arriving in CHS. A compressor stall or any serious issue would’ve left the plane out of service for much longer than that.
I will look into this further and get back to you all.
I sat through hours of ATC audio archives. The pilots of UA 3437 did not tune into ZNY (DIXIE Low on 118.975), NY Approach (ARD Sector on 128.550), or NY Approach (MUGZY Sector on 127.600).
You likely heard another aircraft with a similar callsign, such as UA 3438, which operated CLT-EWR and landed at 8:48 PM EST on 01/03/22, just under two hours after UA 3437 diverted and landed in CHS at 6:51 PM EST on 01/03/22.
