2003-10-08: TSB Update A03A0110: The Air Canada Airbus 319, operating as ACA 637, was on approach to Halifax Intl. Airport when the crew declared an emergency due to a landing gear malfunction. The crew were unable to extend the landing gear using normal means and requested time to lower the gear manually. Once the gear was down and locked the aircraft landed safely on RWY 06 at 1302 ADT with airport emergency crews standing by. The aircraft stopped on the runway until maintenance confirmed that the landing gear was locked down then the aircraft was towed to the gate. Maintenance reported that the aircraft was operating under MEL with the #2 LGCIU (Landing Gear Control Interface Unit) inoperative. At some point during the flight to Halifax the #1 LGCIU failed which prevented the landing gear from being lowered normally. Maintenance replaced the #1 LGCIU and completed a byte test confirming it as serviceable. Troubleshooting was carried out on the #2 LGCIU and a byte test was completed; the unit was found to be serviceable.
