New Northwest Arkansas Talkgroup

[Ozarkz]

Been getting a hit on this talkgroup off the Benton County Simulcast (773.33125) and the Fayetteville Simulcast (856.7375) via SDRTrunk, is encrypted so haven't heard any traffic on it:
53659

Given that 53658 is Event B for Washington County Sheriff, could this be another event channel?

Got another hit with another new TG: 53883
Became very active with the aircraft emergency at XNA earlier tonight

"Units" referred to their dispatch center as maintenance.
"Maintenance I've got an alert inbound, 10 minute ETA, alert inbound, alert 3, one soul on board. I need you to go get a trailer."

Could this channel be XNA maintenance traffic? Haven't gotten much on the previously discussed channel 53659 but this one seems to be some airport ops.
