This sounds simillar to the Canadian story. Why can these guys not recover
from the spins if they are so high?

The Cirrus cannot recover from spins. Here is a quote from the SR22 manual:

Spins

The SR22 is not approved for spins, and has not been tested or

certified for spin recovery characteristics. The only approved and

demonstrated method of spin recovery is activation of the Cirrus

Airframe Parachute System (See CAPS Deployment, this section).

Because of this, if the aircraft “departs controlled flight,” the CAPS

must be deployed.

While the stall characteristics of the SR22 make accidental entry into a

spin extremely unlikely, it is possible. Spin entry can be avoided by

using good airmanship: coordinated use of controls in turns, proper

airspeed control following the recommendations of this Handbook, and

never abusing the flight controls with accelerated inputs when close to

the stall (see Stalls, Section 4).

If, at the stall, the controls are misapplied and abused accelerated

inputs are made to the elevator, rudder and/or ailerons, an abrupt wing

drop may be felt and a spiral or spin may be entered. In some cases it

may be difficult to determine if the aircraft has entered a spiral or the

beginning of a spin.

• WARNING •

In all cases, if the aircraft enters an unusual attitude from

which recovery is not expected before ground impact,

immediate deployment of the CAPS is required.

The minimum demonstrated altitude loss for a CAPS

deployment from a one-turn spin is 920 feet. Activation at

higher altitudes provides enhanced safety margins for

parachute recoveries. Do not waste time and altitude trying to

recover from a spiral/spin before activating CAPS.

Inadvertent Spin Entry

Sounds like legal-speak to me. I'm am willing to bet that Cirrus has spun
the hell out of that design with pleasing results.

That is apparently what cost Astronaut Gorden Fullerton his life, when
he was testflying a Cirrus.

That will come as a surprise to him. :-) You're thinking of
Bob Overmyer, but he was killed in a VK-30, which was a completely
different airplane, a kit put out by Cirrus before they certificated
the SR series. Fullterton is still alive, BTW.

Boy I bet he's glad about that :-) Thanks for the clairifaction.

You are right! My bad! I am glad that GF is still with us.

Actually, no pilot has ever reported recovering from a spin in a Cirrus. It
is not for lack of trying. There are numerous reports of Cirrus aircraft
crashing (or they would have crashed if CAPS had not been deployed) after
the pilots entered a spin, however.

It

crashing (or they would have crashed if CAPS had not been deployed) after
the pilots entered a spin, however.

I don't agree. What there have been is a few low altitude spin ins and a couple
of crashes involving pilots not deploying the chute. However, there is no indication
that they attempted to recover from (or even recognized they were involved in) a spin.

Searching the NTSB for Cirrus:

1. Stall/spin immediately after takeoff (treetop level). SR20
2. Pilot deployed CAPS in IMC after insturments became unreliable SR22
3. Botched landing due to brake failure. SR22
4. Wire strike during simulated forced landing SR22
5. Low altitude stall due to evasive manouvering in the pattern. SR20
6. Crash from low altitude pass SR20
7. Wire strike. SR20
8. Spatial disorientation followed by a high speed impact with the ground (unlikely therefore
to have been a spin). SR22
9. VFR-into-IMC CFIT SR20
10. Collision with deer SR20
11. CAPS deployed after aileron falls off. SR22
12. Mountainous terrain/Density Alt CFIT SR20
13. SPIN FROM 5000 FEET. SR22
14. Spatial disorientation and CAPS wouldn't deploy, collides with trees on emergency landing. SR22
15. Emergency landing due to failure to replace drain plug SR20
16. Forced landing due to fuel mismanagement. SR22
17. Botched landing SR22
18. VFR into IMC CFIT (mountainous) SR20
19. SR20 test crash (aileron jamming)
20. VK30 CG test results in spin.
21. VF30 engine fire forced landing

Plus there are two more that don't have enough information to determine. However
I suspect one was a botched illicit IFR approach. The other was a fatal in Spain.
As far as I know ther ehave been FOUR Cirrus deployments (counting the most
recent one) Of which only the last one as near as I can tell might be spin related.
The others were PANIC button pulls from mechanical failures or disoriented pilots.

So at the most we've had one SR20/SR22 crash from a spin that the pilot might
have thought to try recovering from (either via CAPS deployment or control input)
and one CAPS deployment to avert a spin.

This doesn't agree with your statement.

Cirrus' manuals treat spins and steep spirals the same. In this case, the
airplane entered a steep spiral.

3. Botched landing due to brake failure. SR22
4. Wire strike during simulated forced landing SR22
5. Low altitude stall due to evasive manouvering in the pattern. SR20


I am not sure what your point about altitude is or why you think it proves I
am wrong, but I am willing to listen to it.

6. Crash from low altitude pass SR20
7. Wire strike. SR20
8. Spatial disorientation followed by a high speed impact with the ground

(unlikely therefore
to have been a spin). SR22


No, but it would have been a steep spiral, which Cirrus seems to think is
the same thing.

9. VFR-into-IMC CFIT SR20
10. Collision with deer SR20
11. CAPS deployed after aileron falls off. SR22
12. Mountainous terrain/Density Alt CFIT SR20


One of these two CFITs had the pilot reporting that he had entered a spin.
Of course, the news reports may have been incorrect.

13. SPIN FROM 5000 FEET. SR22
14. Spatial disorientation and CAPS wouldn't deploy, collides with trees

on emergency landing. SR22
15. Emergency landing due to failure to replace drain plug SR20
16. Forced landing due to fuel mismanagement. SR22
17. Botched landing SR22
18. VFR into IMC CFIT (mountainous) SR20

I count four spins.
