Narrative:
The landing gear didn't extend and the pilot went around. By using an alternate emergency gear extension procedure, the crew tried to extend the undercarriage , but attempts were unsuccessful. The crew elected to make a belly landing at O'Hare Airport. It appeared that the gear selector actuating rod was disconnected from the normal gear retract and extend actuating assembly. The crew damaged the manual gear extension mechanism in the manual extension attempts.

PROBABLE CAUSE: "Improper procedural checklist in which a critical step was not listed. "
