A REX Regional Express Saab 340B, registration VH-NRX performing flight ZL-768 from Albury,NS to Sydney,NS (Australia) with 16 passengers and 3 crew, was descending through about FL120 towards Sydney cleared to descend to 8000 feet when the crew declared PAN reported they just had had uncommanded engine (CT7) operations, the right hand propeller had sheared off, they still were able to fly with normal handling of the aircraft. Air Traffic Control stopped departures and sent arriving traffic into holds advising a runway inspection was needed, only one runway would remain available and they couldn't estimate when the second runway would become available again due to the landing with one propeller sheared off. A second PAN aircraft (medical emergency), that had earlier been assigned to runway 16R, too, was reassigned runway 16L. The Saab continued for a safe landing on Sydney's runway 16R about 25 minutes later.
