![]() "Ron Natalie" wrote in message m... Actually, no pilot has ever reported recovering from a spin in a Cirrus. Who would he report to? 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. 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 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 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. I count four spins. |

In this case, the airplane entered a steep spiral. But that wasn't your assertion. Your assertion was that spin recovery was either fatal or resulted in a CAPS deployment, with the implication being that spin recovery by control inputs was not possible. Sprials are a completely different beast. 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. Because my assertion is that no matter what the method for spin recovery would be (in whatever aircraft), recovery from such a low altitude spin would have been unlikely. 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. But that wasn't the point you claimed. You claimed that people were dying because there was no way to recover from the spin. 9. VFR-into-IMC CFIT SR20 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. Neither is apparent from the NTSB report... One showed the aircraft entering pretty much flat and straight ahead, the other showed failure outclimb obstacles at a reduced peformance (DA) condition. I count four spins. I don't. I count at most one spin that could have been recoverable if the aircraft had conventional spin behavior (and it has yet been proven that the Cirrus can't be recovered by some control inputs). Your assertion of numerous crashes as a result of spins and/or deployments is not supported. Even by your own optimistic view it's only 4. |

I am amazed at how people seem to think that average is acceptable. A new design should be SAFER than a new 182 other 40 year old design of similar class. Progress is called for is it not? btw, there are 2 in the last few months, this and canada. Combine that with the guys that were "going out to practice stalls" and you have 3 that I know of. I couldn't get through all your guys mishmash to see what other one is arguable. |

I am amazed at how people seem to think that average is acceptable. A new design should be SAFER than a new 182 other 40 year old design of similar class. Progress is called for is it not? Not necessarily. The Cirrus design is a *high performance* airplane with "fixed feet". Pilots appear to be treating it like any other "fixed gear" airplane which it's not. On top of that they have the BRS and to cover an apparent and admitted inability to recover from a spin. So, you have, in general, pilots with a fixed gear attitude flying an airplane with a retract attitude. It is deceptively slippery. It is 20 knots faster than the typical Bo and is definitely not a short field aircraft. According to the pilots of the one on our field it is a plane you fly on, much like the G-III or Lancair IV. They specifically say it lands fast and is not a pane for full stall landings. I would be very interested in how it handles accelerated stalls. Overall in my opinion and it is just that, an opinion, the plane could use a larger tail and rudder. Any plane that whose POH says "pull the chute" in a spin, or steep spiral needs a bit more work. btw, there are 2 in the last few months, this and canada. Combine that with the guys that were "going out to practice stalls" and you have 3 that I know of. I couldn't get through all your guys mishmash to see Practicing stalls in high performance means that most likely, sooner or later, it is going to drop a wing. An uncoordinated stall brings a spin *entry*, but a real spin takes time to develop. If the pilot is not familiar with spins and high performance he/she is most likely to use the ailerons which will accelerate the entry. I do not know how Cirrus handles this situation, but the new owners out here said you do not do uncoordinated stalls in the SR-22. That scares me a bit as sooner or later one will happen, be it in rough air, or a mistake in practicing.

Roger, I am with you on your points, but I have to say that it seems the
Diamond Star (admittedly not hi performance) and Lancair 400 have managed to create wings that are efficient and stall/spin friendly. I think that we should expect a new design to be better in these areas due to all our new knowledge, tools, and materials. I guess I am just to demanding? At any rate, you are right on about pilots not being ready for the Cirrus planes, and I don't see the 20 being any easier to fly than the 22. |

Your assertion of numerous crashes as a result of spins and/or deployments is not supported. Even by your own optimistic view it's only 4. I plead guilty to the charge of pessimism. I think we are talking at cross purposes here. I am going by what the manual says, which says that spins have not been tested and the only approved method of recovery is by deploying CAPS. I also think the number of stall/spin accidents is excessive, given the small size of the fleet and the fact that the Cirrus is supposed to be especially resistant to this type of accident. I think the thing that really bothers me is the implicit criticism of the pilot who merely followed the procedures in his manual, as well as the religious like fervor with which some people attack anyone who dares to say anything they perceive as negative about Cirrus, even if the information comes from Cirrus itself. I see no particular reason why the Cirrus should have any method of recovery from spins other than deploying CAPS. If there is, fine, but why bother? If the airplane is supposed to be spin and stall resistant and the pilots are trained properly, then this type of accident should be much more rare than it seems to be. |

are trained properly, then this type of accident should be much more rare than it seems to be. The airplane is supposed to be spin resistant. I don't recall any knowledgeable person claiming that it is stall resistant. As with most general aviation airplanes, you can pitch it so that the angle of attack exceeds the critical angle, and the wing will stall. Regards, -Mike |
