I will be going to the AP in a day or so. Can you wait?

Maybe it was messed up when they did the split on it. It looks like the n ose bowl fit could be improved. It will mess up the paint job but since it's fiberglass it can be made to fit better with some fiberglass work and a lot of effort. Pictures attached below. Note the horizontal seam where the upper cowl door m eets the lower cowl side. Extend an imaginary line on this seam toward the p rop. You should see that the nose bowl seam is no where near that imaginary l ine. It is down significantly and it is not parallel. I think this is the c ause of your gap on the top corner where the cowl door should rest on the no se bowl corner. In addition, another source of the misalignment is that there is no spacing a t the nose bowl seam. When the nose bowl is cut for the split STC there is material lost with the c ut. The pictures show that there is no gap at the cut. The cut surfaces were laid on top of each other without any gap and the screws were placed to hol d it there. This would be where to start a fix. You might close your gap at t he corner by moving the screw holes to hold a gap here. As a result the seam will have a gap. You could fill the gap with epoxy if it gets unsightly. After the nose bowl is fit properly if there is still a gap one could build u p the fiberglass in the corer where the problem gap is. You could also use a stinker on the aluminum upper cowl door in that corner if you think it has b een stretched. But that is the last resort as it may crack.
