HAL A321 circling around KSEA

Anyone know what’s going on with Hawaiian Airlines 8027? It was flight planned from KPAE (Everett, WA) to HNL but after takeoff it went into a hold over SEA and it just did a low approach.

There is a company here at Paine Field that does refits, updates and C/D checks on heavies. Im guessing something went amiss after take off and they went into hold to work it out or plan if they want to land or continue. More than likely in communications with home base. I see on the flight its now continuing on to HNL, so Im assuming they worked it all out.

Everthing must have went fine. Its scheduled for a revenue run today
