>Is this a problem with joining carbon fiber? Fundamentally? No. That said, I imagine there's a lot of pressure from the management to make big, expensive, slow-to-manufacture subassemblies fit together, even when they maybe don't quite. Not sure if it's an issue with their tolerances, or if something bigger is going on (the skin roughness they mention is troubling, because it implies the carbon layup might not have been compressed enough during its cure, and would require significant reinforcement at the very least to meet minimum strength requirements--an aircraft that can't even reach its limit load is fantastically unsafe to fly), but joining composites is mostly about having good procedures and following them religiously.
