"Based on the limited information available immediately after the accident, the 21 GA8 aircraft operating in New Zealand were grounded, as well as a number operating overseas. There were 63 aircraft grounded in Australia for the same reasons," Director of Civil Aviation Graeme Harris said.
The precautionary suspension was triggered after initial information from the Swedish showed the aircraft had broken up in flight.
However, the director said he had received further information that there was no evidence to indicate a potential unsafe condition. As a consequence, the GA8 aircraft type would now be safely allowed to return to normal operations.
"They can now be assured that the initial concerns expressed following the accident in Sweden have been addressed."
"We do not take these steps lightly," he added. "The flying public, operators and pilots of the affected aircraft need to be satisfied that these aircraft are now safe to fly."
CAA's Australian counterpart, the Civil Aviation Safety Authority, has an airworthiness engineer in Sweden observing the accident investigation.
Mr Harris said feedback had been beneficial. "We will continue to monitor the investigation into the GA8 accident and will take appropriate action should any related safety issues become apparent in the future," he said.
