The Civil Aviation Safety Authority (CASA) has suspended operations of the GippsAero GA8 aircraft for 15 days as a precaution, as investigations continue into the cause of the crash near Umea in northern Sweden on July 14.

All nine people on the skydiving flight died in the crash.

"While we gather more information about that, we thought it was prudent to put them on the ground," CASA spokesman Peter Gibson said.

Swedish authorities have expressed concern that the aircraft may have broken up during the flight.

CASA said there were 228 of the planes in service globally, including 63 in Australia.

Spokesman Peter Gibson said the GA8 was first certified in 2000 and had not had a difficult safety history prior to the crash.

He said GippsAero held a production certificate issued by CASA to manufacture the GA8 and was subject to regular surveillance and safety checks by the authority.

The GA8 is a single-engine high-wing aeroplane with fixed tricycle landing gear.

It is used in Australia for a range of purposes, including charter flights and skydiving.

CASA has written to all Australian operators of GA8 aircraft, advising them of the suspension.

It has also written to all national aviation authorities who have GA8 aircraft operating in their jurisdictions.

In response to CASA's suspension, the European Union Aviation Safety Authority has issued an emergency airworthiness directive to European GA8 aircraft owners and operators to not fly the aeroplane except for ferry flights — for example, to return the aircraft to base.

CASA has sent an airworthiness engineer to Sweden to observe the accident investigation.
