Analysis

During the taxi for takeoff, the crew noted a hydraulic malfunction on the right main gear and returned to the gate for maintenance. The aircraft was shut down and turned over to the maintenance crew for repair. The passengers were not deplaned. During maintenance troubleshooting procedures for the hydraulic leak, the gear handle was raised without the gear locking pins installed. This allowed the nose gear to retract and the nose settled onto a parked tug. Investigation revealed that the applicable checklist was not used and positive communications were not established between the maintenance personnel in the cockpit and those on the ground.
