Every aircraft has some missing screws. Literally every aircraft. That's why there's so many of them. Some of them matter, and the pilots keep a close eye on those during the preflight checks. Others, matter less so. (A single missing screw on a prop spinner - big problem. A missing screw on a non-structural plastic aerodynamic fairing - okay to defer, literally zero risk.)
