Every iv-p that I have seen has these cracks which I assume are coming from the expansion and contraction of the fuselage during pressurization cycles. I have been told in the past that these cracks are in the micro only used in the body work. In fact when my airplane was repainted last year we verified that the cracks were in the micro when it was sanded down, but I would be interested to know if anyone is aware of cracks extending into the structural carbon fiber and has it caused problems. Has anyone had to reinforce their fuselage and if so how was it done?
