Narrative:

After takeoff, the nose gear failed to retract. We performed appropriate checklists which called for recycling of the gear. This did not correct the problem and we returned to the airport. On the ground it was discovered that the nose gear pin had broken and the outer sleeve had remained in the nose gear when the central barrel and flag were removed. A maintenance write-up was performed by the captain, the nose gear was inspected and the flight departed again without incident.
