My office is at Springs airport. The discussions doing the rounds based on bits and pieces from different people on the field or in the circuit. :

There are no eye witnesses that saw the aircraft enter the spiral/spin. Someone (not sure if it was pilot waiting to takeoff or not) watched the initial takeoff then looked away. He then looked back and saw the aircraft was nose down and presumably in a spin at about 300ft.

The observer heard a bang and saw a puff of smoke just before the aircraft dropped out of view. This is presumed to be the ballistic parachute being activated.

I’m not claiming any of this to be an accurate chain of events - it is only what I have heard from reliable sources.

I guess we have to have the discussion about whether or not the BRS chute deployment changed this from a survivable to a non survivable crash.

There is a height limit on the chute for a reason and that is because the deployment sequence places the aircraft nose down and at a high rate of descent. On the Sling which has (I believe) the same Magnum BRS chute system the min deployment height is 1000ft. The Cirrus can deploy at 600 to 500ft depending on model.

Very sad accident.

Indeed. It would also be interesting to know what the probability is of an uncommanded activation of the BRS.

What's left of this aircraft is in a skip waste bin at my office. Not good at all...…………...

KINGAIR ..

Do you have any photo's of this ?
If so - please post ….

It would be very presumptuous to "assume" the crash cause is clear and simply dump the remains in a skip....
As Peregrine stated - an un-commanded activation of the BRS should be looked at closely …

I assume the SACAA is looking at the wreck / cause of the crash ….. :?:

With regards to the questions about the ballistic parachute...

apologies if my comments were not clear on this...

The puff of smoke was seen coming from the aircraft WHILE it was in the spin just moments before impact - and just before the aircraft dropped out of view behind trees. Not before entering a spin/spiral. (the observer heard the bang and saw the smoke - did not see the chute deploying .... it did not have enough time to deploy)

Having spoken to people that viewed the accident site, the chute was laying next to the wrecking semi deployed.

Look on google maps. Options are not good. Oval is the approximate crash site.

Thanks JCA - not great, but anything is better than spinning in.

Check this report from a eerily similar accident to a Polaris in Belgium. In the report they speak of a proclivity to Spin easily

And a little strange that a photo of the very aircraft that crashed at Springs is used as a file photo for the Belgium report....

To slow, up to 2sec of video you can see the right turn before stall and spin.

That's a scary Video Neville. What type of a/c? - it looks like an RV from the low aspect ratio.
It also looks like he was banking right but spun left.

Looks like top wing stall from to much rudder.... thats really steep bank angle for so low......

From the partial date, is guess its the aircraft involved in this thread (01-12-20xx) ?

To add a little context to the video..

Yesterday one of my colleagues had the good idea to check our archive CCTV footage from Sunday and realised we had captured the accident although from quite some distance. So this is shot from a hangar on the south side of the field.

The aircraft comes into frame in a steep right hand turn approximately 90 degrees right of runway heading. I can only guess he was attempting to turn back to the runway following a loss of power. What follows requires no further explanation.

The low resolution video does not show it but a puff of smoke is emitted from the aircraft shortly before it drops out of view. This being from the ballistic parachute being deployed.
