Your welcome unidev. Because I know that when running the MBA without Wifi there is no black out at all . I have tried even that. TBH its all about the eco-system I believe OS X is quite stable and even MBA ( not being a fan boi ) I have a retail shop and I sell laptops / pcs / Apple for a living . But yes the Black screen issue is a plague that needs proper investigation, have had a lot of client complaining.
But the size / form factor and mobility along with performaces outweighs this technical blunder.
In the long run we are damaging the HDD even if it is a PCIE SSD due to force shut down or incorrect force bootup via the PRAM reset method.
Good Luck unidev.
Will update posts if any more findings pop up for the community.
I just started getting this problem yesterday. I am on 10.8.5 and I think I upgraded not long before I started getting this issue (basically a few days ago max.).
I also have the Chrome graphic glitch: http://forums.macrumors.com/showthread.php?t=1613841
As I wrote there, my issues is that after leaving the macbook closed for a longer time (hours), when I open it the screen just stays black like it's off (I can't really tell if it is or not). I have to hold the power button and maybe even press it again to make it power on (it doesn't instantly throw me into the desktop, it's the grey apple logo screen booting etc). I didn't have this problem until a few days ago and I think 10.8.5 might have actually cause it. It's that or my hardware is failing

I have been experiencing this issue with my 2013 13" MBA since I got it in June. It looks like there are a few different variations of this problem listed in this thread, so I’ll try to describe what I’ve experienced.
Here are my Energy Saver preferences:
Turn display off after: 2 min
Put hard disks to sleep when possible is checked
Turn display off after: 10 min
Put hard disks to sleep when possible is checked
The problem: after I have been away from my computer and my display goes to sleep, I will wake it and log in— and after a few seconds, even if I’m typing or using the mouse, the display will go black and the computer goes to sleep. I am then forced to wake it and log in again. In some instances this has happened over and over. One thing that I noticed: my external hard drive will power down and any music being played will stop once the computer goes into this second unexpected sleep. This leads me to believe that the second sleep is different—the computer is going into a full sleep, and not just a display sleep.
After updating to OSX 10.8.5, the problem did go away for a while, and I noticed that the computer was waking from sleep instantaneously, as opposed to taking a few seconds like it usual does. Last night, I unplugged the magsafe power adapter for the first time since the upgrade, and as soon as I did so, I heard my external hard power down and the computer went to sleep. Since then, the computer is slow to wake from sleep, and I did experience a black out—even with the magsafe cord connected. There were absolutely no problems for the week or so that I had the MBA plugged into the adapter after having updated the OS.
I’m not sure what all this means, but I hope that this can give some hints to others as to what is going on.
DanBoulet: I experienced a similar issue like you described (after waking, it would sometimes go to sleep again after a few seconds), on my old Macbook Pro 13 2010. It was definitely a software issue as I otherwise had no problems whatsoever with the laptop. For me it was not really annoying as it happened pretty rarely and after a few seconds I could wake it back up with a touchpad click. Just wanted to let you know.
well, that will teach me to spend 10 days saying how all my problems went after removing chrome!
last couple of days i have had 2 ir 3 blackouts each day.
As with Mrbrdo, it is not a show stopper....but annoying nonetheless. & I don't recall changing anything (not yet gone to 10.8.5 - has the camera bug with skype been fixed yet ?)
You're just wasting your time. If you want to find if the update fixes the problem, then update and try.
Apple is just going to say that you should always update to the latest version, and they're right to say that. If they wanted to admit or realized that an update is causing problems then they would stop distributing it.
I occasionaly provide IT support and people like you really annoy me. Use your brain.
