Narrative:

While replacing the APU on aircraft xyz, a B727 in air carrier airlines fleet, we had difficulty installing the exhaust duct on the APU and the clamps on the load control vale. Once the installation was complete, we noticed the aircraft was to depart in about 1 hour. While finishing the overnight check and other maintenance items, we overlooked the removal of the beam in the right wheel well area used for the hoist to remove the APU. Subsequently, the aircraft departed cvg and the main landing gear would not retract. The aircraft returned to the gate and maintenance removed the beam with no damage and the aircraft departed cvg.
