seperation required?

My first flight indoors did not as expected, bumped into a wall and P3 fell about 4 feet, broke a prop and this.  Flying just fine otherwise.  
Not sure if I am seeing a part of the locking tab, does not seem to want to move back in.  I am wondering if I should seperate the shell to have a look.   
Will have to pick up a T6 to remove the end screws, but I was wondering if it is very tricky unlocking the locking tabs.

Oops...Minor separation, can be cured either by snapping back in (your risk) or disassembling that portion and having it go in without the risk of snapping that tab....
Check the videos on disassembling otherwise it will be painful...Start from the end...hint..hint!!...watch videos.....

Yeah looks like a tab, go on Youtube and type in "Phantom 3 shell replacement",  some good videos showing the shell replacement and innards, interesting viewing.

It would be better to replace the shell
