After a temporary suspension of flying operations for the Australian Army's Sikorsky S-70A-9 Black Hawk helicopters since the 19th of January upon the discovery of a number of fractured bolts during a routine maintenance check, the fleet has returned to full flying operations following the lifting of the suspension.

A thorough engineering investigation was carried out following the discovery of the defective bolts, and results have indicated that the defective bolts were confined to a single manufacturer’s batch and were not a fleet wide issue. The defective batch of bolts has been quarantined from use.
