Last night at DEN I observed this HP 733, N316AW parked at the west end of C concourse, not docked to any jetways...as you can see there is a large gash in the outer skin just aft of the rear door...anyone have an idea what caused it and what the plan of action is to repair something like that? I'm guessing that such a small bit of damage isn't enough to ground the aircraft...am I correct?
I apologize for the quality of the photo but between bad light and inadequate equipment thats the best I could muster...the damage is still pretty discernible though...

Looking at similiar photos I see that thing on every other 733 tail so it looks like you guys were right...Ive never seen that before and last night when I saw it looked like it had jagged edges and was not supposed to be there so I thought the aircraft had been damaged in some way...perhaps a ground collision or something like that...its good to know that everything is supposed to be like that...
Thanks for your help,

Actually the deflector looking thing is called a Vortex Generator and is used to modify the airflow into the apu inlet and ensure it's laminar and not supersonic.
To the original question; any damage induced hole will ground the aircraft until it can be inspected to determine damage extent and temp repaired for ferry to a repair facility. Its revenue days would be over until it was repaired.
This isn't the Air Force where ABDR is considered acceptable.
That's not to say there haven't been holes in aircraft that went overlooked for a time (jetway bites are a most common cause).

FWIW, my CDL (49-15-1) shows it as the APU Inlet Flow Deflector. The vortex generators (see the China Southern photo) I believe are the ones at the top of the fuselage between the horz/vert stabs, 3 on each side... Aft body vortex generators, CDL 55-xx-xx (exact number escapes me.)
