I don't know if this has been discussed here previously so I will post it.

It almost sounds like pilot partial or complete incapacitation.

Bummer, indeed. I don't blame the plane. It does sound like the pilot was distracted or disabled.

I thought the Skycatcher is unable to do spins, or at least very difficult to spin.

Twice during practicing power-on (departure) stalls, I let the left wing drop. Must be quick on the right rudder! Don't attempt to level with ailerons! Also, the article apparently quoted the POH as saying reduce power(?!) True, once a spin has developed (PARE). But when recovering from a power-on stall, I was taught to leave in full power until recovery was complete and a positive rate of climb (Vy) was established.

Skycatcher POH : "Power -on stall recovery should be initiated by simultaneously lowering the nose while reducing power after which normal power -off stall recovery techniques should be applied."

I don't think that's true at all. One of the prototypes was lost in spin testing (BRS deployment, pilot ok). The tail was redesigned before production to make spin recovery more effective. They will still spin, but now at least you can recover them with standard inputs! :)

I have the POH here and I will go back and check it. What you say does make sense, as the combination of high power, low airspeed, and high angle of attack in the departure stall configuration does cause a severe left-turning/rolling tendency, which if unchecked in the break seems to cause that left wing to drop suddenly, possibly causing a spin. Pulling the power might prevent that, followed by slowly advancing throttle and correcting with right rudder. Maybe I was taught wrong :| at least for this plane.

The way you were taught is the normal way to make a recovery from a power on stall, at least from the FAA's standpoint. That being said the manufacturer's procedure should take precedence over the normal recovery technique if they are different.

Well, Section 4 Normal Procedures, page 4-41, STALLS. Yep. That's what it says.
