Hi, I'm new in the forum and apologize in advance if i'm posting this in the wrong place.
I Recently flew with Air Asia Indonesia QZ8496 from Bali to Singapore. I'm obviously not a professional but I think it is a A320 Airbus. Sitting just behind the left wing I could not help to spot what looked to me as a patch job on the wings (flaps?) which by the looks of it have been sitting there for a while and had what looks like a large crack or tear on the part closest to the fuselage.
Is this something to worry about? Why does the wing look patched up in the first place? I fly with AA-Indonesia every few months but this has me questioning whether they are safe or not.
Here's the photo I snapped from my window:

Thank you in advance.
