During climb out of Sydney the left engine oil pressure warning illuminated, associated with a falling oil pressure indication. The left engine was shut down. ATC were advised of the problem and the aircraft returned to Sydney where an uneventful single engine approach and landing was carried out. Investigation revealed the rear bearing oil scavenge line was cracked and the rear turbine blades showed evidence of foreign object damage. Engine strip revealed a low pressure turbine blade had failed from fatigue. There is an improved blade assembly now available which the operator is using to upgrade the fleet.
