Spin anyone?

2 wrongs don't make a right - but 3 lefts do.

Been there in training, never took hardly anytime at all to recover, though. Full left rudder should have fixed that, especially after most jumpers were out of there.

I read the captions in the video but I don't quite get it; what causes the wing to stall "at any altitude/airspeed"?

Was this from the increased drag from the door open and the jumpers hanging out, weight distribution problems, turbulence?

I'm surprised no one's blamed the spin on the guy's GoPro yet!

It's all been said before, no sense repeating it here.

Pretty sure the pilot was wearing one.

Jumping out of a spinning plane is fun as hell. Almost as fun as letting jumpers out of a spinning one. But maybe this one is not on purpose?

That's a general point about stalls - they are a result of esceeding the critical angle of attack (angle between chord line of wing and airflow), and it is therefore possible to stall a wing at any speed (of course, attempting to fly too slowly is very often what causes AoA to get too high).

Well, an open door with jumpers hanging out of it is something that's going to happen on pretty much every skydiving flight you're going to make, so the pilot really should be ready for it!


Although I'd imagine those two guys sitting right in the boot making no apparent attempt to move forward may be part of the reason the recovery took so long. Pilot seemed to fly out of it pretty quickly after they finally shifted. (But that's pure speculation and I may be talking utter bollocks).

Do you want to have an ideagasm?

So assuming it was AoA, why was the pilot not flying level on jump run? Or if he was level, was he just flying ridiculously slow? Maybe some sort of accommodation for the tandem passenger?

The jumpers hanging out aft of the door makes sense in terms of weight distribution, though would that have created the problem in the first place or just intensified it after it started?

No assumption needed. No spin without a stall, and a stall requires the critical AoA to be exceeded.

The only sure way to survive a canopy collision is not to have one.

Well the pilot without a doubt held it in a spin, maybe not on purpose though. I can't imagine a tailwheel pilot that cannot recognize a spin.

Seemed like a few jumpers were in on it though, and a few of them not.

I'm no pilot, so take it for what it's worth.

I see NO reason for a pilot to slow the plane down to accomidate a tandem student. None... Actually, if he got it slow enough, it could make their exit less stable (think flopping around until you hit a good airspeed)

Again, not a pilot... but I think the stall speed is different when the plane is most weight aft.

a few other things.

How about the reserve handle out

What about tapping the pilot on the shoulder when he is dealing with an issue? Was the jumper looking for direction? Pretty sufice to say GET OUT no?

Looks like the pilot was NOT dealing with an issue. On the other forum I read that he did not know he was in a spin . He thought he was in a spiral dive.

So, the skydiver was probably asking and gesturing "What is going on?!?!?! Do something! Why arn't you doing anything?!?"

Angle of attack is the angle between the cord of the airfoil (wing) and relative wind. You exceed the critical AoA and you stall; decending, climbing, climbing, or turning.

Reserve handle was interesting.

Also anyone notice the instructions at the end of the video. One was if you can't out, pop your reserve and maybe static line your reserve if you are thrown out the door at a low altitude.

That's not funny dude, someone actually think that's the appropriate action.

+1 Some pilots are sub standard. A bad pilot can kill you as surely as landing a bag lock.

Pilot got out though (according to you tube comments).

[riggerrob 643]

During the Islander spin, note that several skydivers fell SIDEWAYS away from the spinning airplane, which meant that the airflow was no longer coming from straight ahead.
IOW, the airplane was SPINNING pretty fast when they finally let go.

That is one intense video!

Totally agree! The guy kept his stick aft as you see in the video. That is NOT what you would do if you would want to recover. Most general aviation aircraft are very docile and would not enter a fully developed spin without positive pilot action or a centre of gravity way aft of limits. By the looks of it with two pilots in front the c.g could not have been much aft of limit if any. So I'm sure the guy is doing it on purpose. One of the jumpers attracted the attention of the pilot and got some sort of denial gesture. So here's a pilot aware of an open door and (unsecured) jumpers in the aircraft, yet provoking a stall spin maneuver. I would say kick him off the premises and tell him never to come back. And be thankful no one got hurt.
