Aircraft; Procedure
Approaching the final fix; when the gear were extended at 160 KIAS and flaps 3 there was a red UNLOCK indication above the green triangle for the left main landing gear; the ECAM L/G LGCIU (Landing Gear Control Interface Unit) 1 FAULT illuminated; and there were flashing XXs for the left main gear on the SD (System Display) wheel page. Indications for the nose gear and right main landing gear were normal. Went around and wanted to do a left turn to avoid terrain but were continually directed to do a right turn and climb so [advised] tower. WX was VMC so turned right and received vectors back around for the ILS 05R due to our low fuel state (6K pounds). Accomplished the checklist for the ECAM. Received word from Tower that aircraft on the ground confirmed we had 3 landing gear down. Landing was uneventful; taxied clear and to the gate.
Approaching FAF; 160 kts; flaps 3; put gear down for landing. Nose and Right main were normal but Left main showed both a green down arrow and a red UNLK. Also the wheels showed a flashing Left main. LGCIU1 (Landing Gear Control Interface Unit) fault ECAM also a landing gear disagree ECAM.Aborted Landing/went around. Controller wanted us to do a right 340 degree turn (mountains right and behind us). Had to comply with less than desirable turn due to language barrier. Worked on checklist for LGCIU1 fault and unsafe landing gear. Fuel was short and based on Tower's assessment of all of our gear being down; we cut off checklists and landed uneventfully.
On approach an A320 left main landing gear indication was a green down; red UNLK and an ECAM LGCIU (Landing Gear Control Interface Unit) 1 FAULT so the Captain executed a go-around. The QRH was followed and safe landing completed.
