By Andrew Osborn MOSCOW (Reuters) - Russia expanded its search on Monday for the remains of a military plane that crashed into the Black Sea, killing all 92 on board, and said pilot error or a technical fault - but not terrorism - were likely to have caused the tragedy. The plane, a Russian Defence Ministry TU-154, was carrying dozens of Red Army Choir singers and dancers to Syria to entertain Russian troops in the run-up to the New Year. Nine Russian journalists were also on board as well as military servicemen and Elizaveta Glinka, a prominent member of President Vladimir Putin's advisory human rights council.
