According to an emergency AD Cessna's quality controls are a bit loose: - Two airplanes with ailerons not engaging the upper stops and one with a flap push/pull rod missing the nut on the bolt. - Elevator cables chafing fuel lines near the fuel selector, which caused damage to the fuel lines. - Elevator trim cables routed outside the cotter pins in the horizontal stabilizer. - Elevator trim cables crossed twice (trim functioned correctly in flight). - Control cables rubbing structures such as bulkheads and center consoles. - Aileron bell crank adjustment screw interference with stringer. - Barrels on control cables not safety pinned or incorrectly pinned. - Control cables routed outside of pulleys. - A bent flap bell crank. I could see mistakes like this happening, but I'm surprised that inspection processes didn't catch all of it. I wonder how much stuff is caught by inspection on the assembly lines?
