Some of those cracks, especially the ones along what looks like the top of the horizontal stab could be cause for concern. One thing you don't want to lose while flying is your horizontal stab. You may wish to have someone more experienced take a good look at this fuselage to make sure that these are not structural in nature.

If these are just surface cracks, well, perhaps a little repair, some covering, or just leave them alone.. and give it a try. But be careful.

Don't just think 'well, if it crashes, well, so what' because that could cause you some severe heartburn. The what if.. could be what if it does break apart in flight and hits someone on the flight line? Then what would you do? Losing the horizontal stab during flight means you have completely lost control of that aircraft and where it is going to go next.
