GippsAero GA8 Airvan Grounded in Australia, New Zealand, and Europe

Sat Jul 20, 2019 6:17 am

The Australian Civil Aviation Safety Authority (CASA) has grounded the GippsAero GA8 Airvan for a temporary period of 15 days, following a fatal accident in Sweden last weekend:

New Zealand’s Civil Aviation Authority (CAA) has also followed suit:

The outer part of one wing (about half of it) broke and fell off, but AFAIK it is not yet clear if this caused the plane to crash or if it was a result of the forces when it went down. I guess that is what they want to find out. There are two cellphone videos floating around, but they show the final dive only, wing already broken.

I know it is most likely unrelated, but this unexplained GA8 accident comes to mind, not least because I knew the pilot and it was a very sad episode: https://aviation-safety.net/wikibase/34483

I wonder if the ATSB will take a look at that one again in light of whatever may be found from this one.

It will be very interesting to see if there turns out to be an issue with the type, or if the Sweden accident was something unrelated to airworthiness. I know there are a lot of operators who rely on the Airvan and who will be waiting for answers so they can have some certainty about their operations. Hopefully those answers come quickly. Difficult times for all involved, and really sad that such an accident took place.

The aircraft had recently (a few weeks before the accident) been checked due to renewal of the airworthiness certificate and the plane is said to have been in good condition.

As for the accident, the plane was flying at 13 000 ft when it entered a steep dive-sharp turn and at about 8000 ft the aircrafts's forward speed dropped to 0
and the aircraft fell out of the sky with the left wing pointing upwards and the right side of the fuselage pointing downwards. The aircraft's fuselage was rotating
rapidly (on around the horizontal axis).

As mentioned, the fact that about half the wing was missing during the spinning descent is not established as either cause of the crash nor the effect of something else. There were 8 parachutists and one pilot on board and the pilot had radioed that they were ready to jump. Therefore flight should have been level and smooth. It seems so weird that the accident happened at that point in time as the forces on the wind should have been at a minimum. I myself believe something else caused a major handling issue (load shift, rudder problem, pilot incapacitation,...) that lead to a steep dive or massive G-forces due to an unexpected turn which in turn lead to the wing break. Of course this is only speculation on my part. They were all from Umeå (population 128k, #13 in size in Sweden) so this is a huge tragedy for the whole region.

The grounding has been lifted by CASA:

EASA has followed suit:

There is nothing on the New Zealand CAA website but I have read elsewhere that they have also lifted their grounding this morning.

Swedish authorities also lifted the grounding. The Swedish AIB says the plane was for some unknown reason exposed to massive G forces that lead to the rear stab and fin being torn off along with part of a wing. They state that nothing seems to have been wrong with the model as such (no apparent design flaws, faulty components and such) and the accident aircraft was well maintained.

9 people on board should have been wearing a parachute, the aircraft was at altitude, yet none made it out. A strong giveaway that something very violent happened, probably knocking everyone unconscious
