An aircraft structure (500) such a helicopter tail fin which is protected from collisions with foreign objects by including a first support (525) proximate to an aircraft structure root; first sheets (545) attached to the first support (525) to form a first leading edge portion of the aircraft structure (500); a second support (530) proximate to an outer end of the aircraft structure (500); second sheets (550) attached to the second support (530) to form a second leading edge portion; and a door (520) including one or more ribs (535a-535g) disposed between the first (525) and second (530) supports and configured to give shape to a third leading edge portion of the aircraft structure (500); and third sheets (540a-540f), attached to the ribs (535a-535g) to form the third portion of the leading edge; wherein the first support, the first sheets (545), the second support, the second sheets (550), the one or more ribs (535a-535g), and the third sheets (540a-540f) are disposed to mitigate damage from a foreign object collision by absorbing kinetic energy from a collision.
