Boeing 747-400, LX-FCL, was operating as flight CLX775 from Calgary Intl, AB (CYYC) to Luxembourg-Findel Intl, Luxembourg (ELLX). During takeoff, the pilots heard a loud bang followed by the stick shaker being activated. The airspeed indicator was still functioning, however the stall margin indicator was lost. The crew continued with the climb and assessed the situation. The crew suspected a nose wheel tire failure and elected to return to CYYC. An emergency was declared and the crew dumped fuel to get the aircraft within landing weight limits. The aircraft landed safely at CYYC with ARFF in attendance. No damage was found to the nose wheel tire. Subsequent inspection by the operator?s maintenance revealed that the right AOA vane was missing, along with evidence of a bird strike. The AOA vane was replaced and a bird strike inspection was carried out. No other damage was found and the aircraft was returned to service.
