Lufthansa A346 at Toronto on Dec 1st 2013 , landed without clearance

A Lufthansa Airbus A340-600, registration D-AIHF performing flight LH-470 from Frankfurt/Main (Germany) to Toronto,ON (Canada) with 307 people on board, was on approach to Toronto's runway 23 but did not switch from approach to tower frequency and consequently did not receive landing clearance, but continued for a safe landing on runway 23.

Canada's TSB reported that the aircraft continued to taxi off the runway for several thousand feet northbound on taxiway H before air traffic control was able to raise the crew on the approach frequency and instruct the crew to stop the aircraft.

NAV Canada reported the aircraft landed on runway 23 without establishing contact with tower, vacated the runway via taxiway H and continued taxi. Tower was able to contact the aircraft via approach frequency and instruct the aircraft to stop, then contact ground. The aircraft stopped just prior to crossing runway 33L and contacted ground.
