We had multiple cracks on the corner radius's, (Radii? Radiai? <img src="/ubbthreads/images/graemlins/confused.gif" alt="" />) That has been the main find in our 150. But, with our mechanic, not to traumatic to repair. But does involve removing the tail structures.
Where are these cracks?
Cessna has out some heavier parts for some of this and before I'd let a mechanic repair anything, I look at parts replacement.
