During take-off, a section of the left engine inlet separated from the aircraft. The crew conducted a fuel dump and returned the aircraft to Sydney with no injuries on board.
Passing about 33,000 ft on climb, the No. 4 engine thrust reduced to about 45 per cent. The flight crew shut the No. 4 engine down. The aircraft returned to Los Angeles Airport and landed without further incident.
Proactive safety action results from SAAB 340 propeller detachment.
It is reported that the right propeller assembly detached in-flight during the Regional Express (REX) flight from Albury to Sydney, with 16 passengers and three crew on board. The aircraft landed safely at Sydney.
An excellent example of effective crew resource management techniques when faced with an abnormal situation.
