Flight Crew Overcame Equipment Problem; Flight Crew Returned To Departure Airport; General Declared Emergency; General Flight Cancelled / Delayed; General Maintenance Action
Aircraft; Human Factors
Everything was normal on the taxi out and takeoff until I asked for gear up. We received a Gear Disagree aural warning and the gear indicators showed the left and right main gear retracted with the nose gear still down. The Captain recycled the gear lever; gear all lowered and the gear indicators were all green. He then selected gear back up; this time the nose and left main gear retracted but the right main gear would not retract; and it kept going up and down. The Captain asked for vectors back to the airport and then ran the QRH checklist following which we left the gear down. All three gear safe lights were green. The Captain took the controls after coordinating with Dispatch and Operations on the ground that we were returning to [our departure airport]. The Captain declared an emergency so that the trucks would be standing by in case of any malfunctions on landing. The landing was normal and we taxied to the gate where Maintenance took the plane from us. In hindsight it probably would have been a better idea to have just left the gear down the first time we received the Gear Disagree message and have headed back to [our departure airport]and not have run the QRH.
...we notified ATC and declared an EMERGENCY; briefed the flight attendants and tried to contact our Dispatcher on company radio but were unable to do so. Thus; we notified Dispatch of our intentions via ACARS. I then made a PA to the passengers. At this point the crew--tired after the four day trip and short rest times--decided not to continue the rest of the round trip due to safety [fatigue] and so notified crew scheduling.
A CRJ-700 flight crew declared an emergency and returned to their departure airport when they were unable to retract all three landing gear after takeoff.
