History
On 29 September 2013, at approximately 19:00 UTC, an Airbus A320-216, registration EI-EIB, operating flight AZ063 from Madrid to Rome Fiumicino, was on approach to runway 16L. When the landing gear lever was selected down, the cockpit crew received a master warning, three red landing gear indicator lights, and an ECAM message reading "L/G GEAR NOT DOWNLOCKED". The crew initiated a go-around and coordinated with ATC to proceed to the Campagnano VOR, where they performed the Quick Reference Handbook (QRH) procedure for the gear not downlocked, without success. They then executed the "L/G GRAVITY EXTENSION" procedure. After completion, the nose landing gear and left main landing gear showed extended and locked, but the right main landing gear remained unlocked, as indicated by a red light on the landing gear downlock indicator.
A low pass over the airport was conducted for visual confirmation. The crew of another aircraft on the ground confirmed via radio that the right main landing gear appeared not extended. The flight crew then returned to the Campagnano VOR to prepare for landing using the QRH procedure "LDG WITH ABNORMAL L/G". After declaring an emergency, the aircraft landed on runway 16L at 19:00 UTC. Following touchdown, the aircraft proceeded nearly straight until it suddenly yawed right and came to a stop off the runway, approximately 10 meters from the lateral edge.
The captain ordered an emergency evacuation. Firefighters arrived, and all occupants evacuated via slides.
Injuries
No injuries were recorded among the 151 passengers or the 6 crew members.
Damage to the Aircraft
The aircraft sustained damage to the right engine and its pylon, the right wing tip, the rear fuselage, and the left main landing gear door and wheels.
Investigation
The Italian National Flight Safety Agency (ANSV) opened an investigation. The aircraft's flight recorders were recovered and analyzed. The investigation focused on the technical failure of the right main landing gear extension system.
