Aircraft; Procedure
Day three of a four day of pairing; we were departing. Right after takeoff we had a L/G LGCIU 1 FAULT. Following ECAM procedures we turned off GPWS system which gave us a NAV GPWS fault. We followed up both ECAM advisory with the QRH and the ECAM Non-Normal Supplemental Manual. We then notified our Dispatcher and Maintenance Control. On final approach to our destination when the gear was selected down; we had a right main gear red unlock light on. We saw three green down lights at the gear indicator with the red unlock light. On ECAM we saw three amber gear triangles and three green gear triangles. We were in CAVU conditions and the traffic was very light. So we elected to go around informing the Tower that we needed vectoring to work with a gear issue. I knew that there was another Company Captain in the cabin commuting home; I called the A Flight Attendant to have him come up to the cockpit. Together we agreed that the gear was down and locked and we could continue the approach for landing. Tower wanted to know if we were declaring an emergency; and we informed them NO; but would like to have the ground standby. I briefed the Flight Attendant what had happened and that we would be making a NORMAL landing which I stated to her three times. I then briefed the passengers why we had gone around to double check the indications and that we were now satisfied and we were proceeding in for our landing. At the gate; Maintenance informed us that there was linkage that was not connected. Maintenance released us after the repair and we continued on to our final destination.
An A321 ECAM alerted L/G LGCIU 1 FAULT after takeoff so the ECAM procedures were followed and when the landing gear were lowered at the destination; three green down and three red up lights illuminated. After a go around to complete the procedures a normal landing followed and maintenance found a disconnected linkage at the gate.
