Presumably those details are in the actual order? Are there any US registered 737-9s with the extra door? Or in neighboring countries that could fly into the US airspace?
Or maybe the operators just look at the plane and sign off based on the fact that the aircraft doesn’t have the part that needs to be inspected.
