Not really a matter of standards, I was more so concerned with doing more damage to the longeron in an effort to get it out (which the OB clearly did and STILL didn't get it out). Since it's not completely drilled thru the longeron I guess I'm hesitant to do more drilling from the bottom to try to extract it. Maybe the acid... or just carefully remove some material around it until I can grip it and wiggle it out then smooth the damaged area.
If the drill tip is loose - or if you can wriggle it a bit ... - you could see if you could get it out with a strong magnet (Rear Earth Neodymium NdFeB) .... or electro magnet ....

I would recommend a Dremel tool or die grinder, with about a 1/8 diameter fine burr and clean the area up removing all traces of the bit and any gouges in the material. I would not necessarily make this a through hole unless necessary to complete the cleanup. After general cleanup, polish and round all edges. That will remoe the stress risers and invole the minimal material removal. From there you can see how bad it looks take a depth dimension and get an opinion from Vans.

I would confirm with Vans, but I think that you would do more damage removing, or attempting and failing, the drill bit.
It will be ugly, but it will be covered and only you will know it's there - the VAF readers will have forgotten...
Check and have Vans clarify their answer.
I'd rather have a bit of damage which I know about, so I can clean it up or repair the piece in question, than have damage down in that hole caused by the drill bit which I *don't* know about (and may rear its ugly head at an inopportune time, like in flight).
