A method and apparatus for aligning a swing tail cargo door. An alignment
system comprises an alignment ramp, a set of pull-in hook mechanisms, and
a set of lock trains. The alignment ramp may be configured for initial
alignment between a swing tail cargo door and an aircraft fuselage during
closing of the swing tail cargo door. The set of pull-in hook mechanisms
may be disposed along an interface between the swing tail cargo door and
the aircraft fuselage and may be capable of a final alignment between the
swing tail cargo door and the aircraft fuselage during the closing of the
swing tail cargo door. The set of lock trains may be disposed along the
interface and may be capable of locking a plurality of latch actuators in
the latched position.
