Touchdown! Greaser!
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?
