Soooo Many Cirrus' For Sale

While the parachute idea did stem from a frank structural failure (mid-air), I don’t believe that many GA aircraft suffer from catastrophic failure of the kind addressed by fault tolerant design. They suffer engine failures to a first order. That’s what the parachute is for.

Though it may have been updated, the POH for my 2003 SR22 listed these as possible CAPS scenarios.

Deployment Scenarios
  1. Mid-Air Collision
  2. Structural Failure
  3. Loss of Control
  4. Landing Required in Terrain not Permitting a Safe Landing
  5. Pilot Incapacitation
 
Max Trescott has an interesting opinion that Cirrus aircraft have a higher approach speed for forced landings than most other single-engine aircraft, resulting in significantly lower survivability during a forced landing, since the kinetic energy (square of the velocity) is so much higher. For this reason, he states (as I recall) that the chute is virtually always preferrable to a forced landing.
The difference in stall speed between my Ovation and an SR22 is one knot. So, I'm not buying it as a "vs other single engine aircraft" thing.

It's not just about kinetic energy, either, it's how quickly that kinetic energy is dissipated. In a normal landing, it's on the order of 10+ seconds. If you can land in a field, it might be in the 1-10 second range, but if you crash into a tree it'll be less. So, an SR22 crashing vs. an SR22 coming down under a chute is really where the difference lies.

If you can get into a reasonably safe situation without the chute, great. If not, it's an awfully nice thing to have in your toolbox.

Though it may have been updated, the POH for my 2003 SR22 listed these as possible CAPS scenarios.

Deployment Scenarios
  1. Mid-Air Collision
  2. Structural Failure
  3. Loss of Control
  4. Landing Required in Terrain not Permitting a Safe Landing
  5. Pilot Incapacitation
The introduction of the blue LVL button took care of #3 for the most part. The Garmin Autoland has/will take care of #5. The other three, I don't think you can safely recover from without a chute.

That said, I wonder what the relative incidence of each of the above is. I'm guessing it's (in descending order) Loss of control, landing required in terrain not permitting a safe landing, pilot incapacitation, mid-air collision, structural failure. No idea as to how different they are, though... And I'm in control of the risks for loss of control and landing terrain, so the thing I'd most like to be able to eliminate the danger of is pilot incapacitation. I'd hate to suffer some sort of "event" and take down my family with me.
 
Is that stall speed difference clean or dirty? If it's terrain that the gear won't help with anyway, maybe keeping the gear up is an option? How much of a difference then?
 
Agreed... But there's a lot of good reasons for pulling the chute anyway. Day VFR, engine fails and you can't make an airport maybe... But night or IMC engine failure, much higher likelihood I'd pull it if I had it.
That's where I'd love to have one. I'm very hesitant to fly my plane over unfriendly terrain, at night, or above widespread low imc. I want to have a chance to find an open field when the engine quits. Flying over the Appalachians last week, I planned my routes to follow highways and keep a landing option within glide range. With a second engine or a chute I'd be much more willing to accept the second two risks. High terrain is still an issue for either solution (single engine ceiling for a twin and difficulty of rescue for the cirrus), but the chute would be far more survivable if forest was the only option. Plus, they still glide just fine, so you could almost certainly get to a road that you couldn't land on, but could be rescued on, before popping the chute.
 
If planes were still being made in any numbers, and the regulations moved forward like they do for cars, every single engine plane would probably be required to have a parachute. Think about how airbags, antilock brakes, and rear cameras filtered down from luxury add-on to required equipment as the technology matured and became cheaper.
It’s honestly pretty surprising to me that it’s still legal to fly over a congested area (think the LA basin, Manhattan, or most other large cities) without either a twin or or airframe parachute. Transiting those urban hellscapes offers no practical emergency landing options, and what few airports are there are increasingly being swallowed up by development.

I’ve been reading this thread with interest, because I’ve just marked 10 years and nearly 1000 hours of owning a Cessna T210N. During that time I’ve done an engine, avionics, interior, and paint. I LOVE my 210. But I’m taking delivery of an SR22T in June. I had several reasons for moving to the Cirrus, and for choosing it over other options:

- 20 extra knots is 20 extra knots; that’s a free 20 knot headwind
- I don’t need the seats or useful load of a 210 (never really did)
- Following from the above, improved fuel efficiency
- Air conditioning for summer days in the southwest
- A desire to have FIKI when penetrating layers in the winter
- Newer system designs with more redundancy than my particular aircraft has
- Retractable gear driving increasing insurance premiums
- Better rate of climb over urban areas
- CAPS for more time spent flying at night, in IMC, over urban areas with no landing options, and freak accidents (which, rare as they may be, are usually unsurvivable: flight control malfunction, structural failure, or midair collision)
- Still fits in a 40-foot T hangar
- Still charged by FBOs as a single engine piston
- Mostly still has the mx burden of a single engine piston

Any one of those is something I “don’t need”, but everything together is a decent sized list. As someone mentioned earlier, it’s also true that when I bought the 210, I was a fairly new pilot (~3 years flying, ~250 hours, and no emergencies). I was fresh from a vacation where I flew a rental Cessna 172 between the Hawaiian islands that was burning a quart of oil every hour. After a few years in the 210, I’ve had a couple of emergencies that led me to look into my soul. I’m 10 years older and wiser. CAPS is an appealing part of the package, and I hope I never need to use it.

No published difference in stall speed for gear up vs. down. And it's for landing configuration, since we're talking about minimum kinetic energy upon touchdown wherever.

What sort of emergencies did you have? Completely understand the appeal of the speed and the appeal of chute (even have flirted with the 22T myself), but for crappy IFR, nothing rides like a 210. Cirrus is pretty nice, must admit, especially for point-to-point traveling. But nothing beats two or three people and all their stuff out of a short grass field like a 210. Maybe a 206 I guess, but there goes what little speed the 210 has...
 
I got checked out and did an IFR IPC in a Cirrus two years ago. A lot to like - But - the FBO apparently had a loss on one airplane because a door caught the wind on the ground damaging it, and slapping the forward area of the fuselage hard - a sheet metal repair on an aluminum aircraft, but near-fatal for this one, as I heard it. Something about it now having damage history affecting re-sale and the high costs required to determine the true extent of the damage and making it good.

Still, if they had been certified such that the chute was optional, could be placarded "inop" instead of the expensive and time-eating re-pack AND if I had the $$$ I think I'd like one.
 
It’s honestly pretty surprising to me that it’s still legal to fly over a congested area (think the LA basin, Manhattan, or most other large cities) without either a twin or or airframe parachute.
?? Is it also pretty surprising to you that it's still legal to drive a car? Those kill far more people on the ground and cause way more property damage than single-engine aircraft.
 
I think your info is a bit dated. Diamonds have had full G1000 with GFC700 autopilot since 2007. Also, Southtec in NC was working on an STC for G3X Touch and GFC500. They've already successfully installed in DA20's. Not sure of current status on DA40, but certainly a lot cheaper upgrade for pre 2007 models with KAP140's.
No, I don't think so. The DA40 community has been begging for GFC500 support for quite some time and so far no dice. Also, how do you plan on upgrading from a G1000 to a G3X? (I know, trick question). But so what are you going to do with a 20+ year old G1000?
 
You can't put a GFC500 in any G1000-based aircraft. Diamond was an early adopter of the G1000, IIRC the DA42 was the first aircraft certified with the G1000. They only built non-G1000 DA40s for three years. There's only about 111 aircraft on the registry from that timeframe, so the market is quite limited... And that's not Garmin's fault.

Six pack DA40s? Ok, that's fair but it still leaves these people without a viable option so far.

I'm just trying to figure out what upgrades it needs. I mean, you can get a supercharger for it if you want... But the mods I can think of on other planes are mostly things that wouldn't apply:

* Already has advanced avionics
* Already has long range fuel tanks
* Already has super clean aerodynamics, so no speed mods.
* Already has a really neat configurable extended baggage system

So, color me confused.

The G1000 is how many years old? You have to live with it forever. Kinda sucks if you ask me. Even in an SR22 you can upgrade the old Avidyne system to Garmin (people have in a G2). DA40 is a trainer and I think we both agree on that.
 
Six pack DA40s? Ok, that's fair but it still leaves these people without a viable option so far.
Yeah, and that kinda sucks. But Garmin is a business, and they need to have a reasonable expectation of ROI to invest in such things. It appears that they're looking to add the C170B, C172 (with no letter, the first year or two of production), and C175 next. I don't know if that represents more airplanes in the fleet than the DA40, but at least Garmin is getting down to smaller fleets. Hopefully they'll get to the early DA40s eventually... But I don't know how small they'll go.

FWIW, S-TEC was taking deposits to decide who to develop for/first. If enough DA40 owners stepped forward with cash, they could make it happen.

And finally... This was your initial post on the subject:

Diamond has a ton a pi$$ poor job of starving the market with inventory and not making the DA40 more configurable via STC.
I do believe Diamond has been a bit stingy about sharing engineering information with potential STC developers, but that's not unheard of nor is it unwarranted in today's world. That doesn't necessarily stop someone from developing an STC.

In some ways, yes. It's definitely going to be harder to upgrade and even maintain far in the future. It's also exceedingly expensive to do the limited upgrades you can do now - The WAAS upgrade (which does give you new computers) is well north of $25K. And as I understand it, you can do that first and *then* you can upgrade to the NXi. $$$$$. I know it's done fairly routinely in turbine aircraft, but it's pretty cost-prohibitive in pistons.

DA40 is a trainer and I think we both agree on that.
Nope. It *can be* a trainer. It's fixed gear and 180hp, though most of them have constant speed props.

However, it's also a dang nice cross country bird if you don't need to haul a ton of gear with you. It's the most efficient certified fixed-gear single in that speed class, it flies nicer than any other plane I've flown except the P-51 Mustang, the view is incredible, and it's reasonably inexpensive to maintain IME.

If I were going to open a smallish FBO/flight school, the DA40 would be one of the first planes I'd put on the line because it *can* serve the trainer role, but it can also be a very versatile rental aircraft.
 
I fly a cirrus for someone under part 91. I absolutely love the plane. I see why people like them. But the cost to do repairs if anything goes wrong is insane. nothing is cheap to do in the cirrus. I feel like the shops look at the cirrus owners as the rich pilot and charge accordingly.

one time I flew the sr20 without ac and I thought I was going to suffocate. the folks owning the cirrus want the latest and greatest so I agree with others that most are upgrading.
 
I'd take an sr22T over an m350 at the same price.

If you are a really big guy, might feel a little cramped in the M350 but have seen some pretty big people fly them. I am 6'2 and 200 lbs, and with the new design seats, I am quite comfortable. But the passenger experience is far better. Much quieter, pressurized, no nose hoses. Flying over the weather as opposed to flying in it is a real blood pressure tool.

Here is flying an Angelflight passenger from Utah to Norcal, over a named winter storm over the Sierras at 24,000 feet in pressurized comfort. Not doing that in a Cirrus. At least not safely with an unhealthy passenger. Very different level of capability and comfort. But also need to invest more time into being pilot, training, bigger hangar, etc.

The one positive item behind the G1000 is that support won't be dropped for that line anytime soon. When several OEMs went with a factory G1000 cockpit, Garmin had to agree to not sunset its support. And given one of those OEMs now offers a G1000 upgrade to the earlier legacy analog cockpits within that model, my take is the G1000 support will last for decades.

I’m also seeing flitestreams added to G1000s now. If that enables pushing a flight plan from an EFB to the machine, that overcomes my biggest grip with the G1000 and that’s the HMI to enter/change a flight plan.

Although continuing support at some point can mean replacing everything at high dollar cost. Electronics from 2005 are long in the tooth and some things will simply not exist at some point, much like the 430/530 screens.

Agreed. But it is STILL a G1000. Not a huge fan compared to say a G3X or G500Txi etc.

Just a point of reference, the TWO schools that had DA40s, sold them. Why? Not cheap to maintain as you think. Because rough landings hurt a lot harder in a DA40 than 172.

EDIT: Yeah, it could be a one/two person XC machine. Better options at 300k!

As for someone developing an STC on their own .... where is that flag when I need it ... :-)
 
Agreed. But it is STILL a G1000. Not a huge fan compared to say a G3X or G500Txi etc.
No argument there. The 430/530 and by extension the G1000 interfaces were clearly programmed by SW engineers who did not fly. Ply upon ply of hierarchical menus. The 650/750/xx5 navigators and G3X were designed by pilots (and the lessons from the 430 in actual use). I'll take a 750 driving a GI-275 over a G1000 any day.
 
It’s honestly pretty surprising to me that it’s still legal to fly over a congested area (think the LA basin, Manhattan, or most other large cities) without either a twin or or airframe parachute.
Adding either of those requirements would be really hard on the helicopter operators.

Except I'm talking about those aircraft where the G1000 is the entire cockpit display and not just used as an upgrade from a 530. In these configurations the cost replacement would border on uneconomical and entitle more than just a box swap as shown in a before/after pics below for a Bell 407. And the G1000 has been standard equipment in the 407 since 2011. So with that commitment in place, I expect the G1000 to be supported and internally upgraded a lot longer than 275/650/750 or G3X. Just something to think of.

You'll find most large urban areas already have various restrictions on helicopter routing with some based on whether its of the single or twin engine variety.

Yes... But that requires either the G1000 NXi, or a software update to the G1000. Since the G1000 software has to be approved by the aircraft OEM, and there's not much incentive for them to do anything for their older birds, I think only Daher (TBMs) and Cirrus (?) have done so.

This software thing is a major drawback of how the FAA certifies the G1000. Garmin should be able to certify the software updates themselves and everyone should have them available.

Just a point of reference, the TWO schools that had DA40s, sold them. Why? Not cheap to maintain as you think. Because rough landings hurt a lot harder in a DA40 than 172.
Our club's DA40 did go through a lot of tires and brakes, but it was still about 40% cheaper to maintain per hour than the metal birds were.

Except I'm talking about those aircraft where the G1000 is the entire cockpit display and not just used as an upgrade from a 530.
The G1000 has never been "just used as an upgrade from a 530", it is a full PFD+MFD glass cockpit including the navigator(s), radios and other avionics. In the piston world, either it came on the airplane or it didn't, there's no upgrade. They do have G1000 upgrades available for the King Air line and some Citations and other small jets, but even when that came out it was $350K to do the upgrade and is probably north of $500K now. Like your heli example, it's just not economical for them to certify an upgrade for pistons.

I think @Trogdor was pointing out the G3X/G500TXi as being a more modern touchscreen system, as well as something that is not the entire avionics suite and can thus be replaced/upgraded piecemeal. If you want to upgrade a G1000 to an NXi, you replace at least both GIAs. If you have a G3X with a 530, you can upgrade the 530 to a 750 without doing anything to the G3X except interfacing it to the new navigator.

In these configurations the cost replacement would border on uneconomical and entitle more than just a box swap as shown in a before/after pics below for a Bell 407.
If you have a King Air or Citation Mustang with the G1000, you can upgrade it to the NXi "starting at 59,990 USD" per Textron. They don't list any other upgrades - It doesn't do them much good to offer support for older piston aircraft. :(

And the G1000 has been standard equipment in the 407 since 2011. So with that commitment in place, I expect the G1000 to be supported and internally upgraded a lot longer than 275/650/750 or G3X. Just something to think of.
So here's the conundrum. Tech moves extremely fast, the FAA moves extremely slow. So, by the time avionics are certified, there are already components in them that are being end-of-lifed by their manufacturers. That means Garmin has one last chance to place an order for as many of that component as they will EVER need, for new manufacturing as well as repairs.

Eventually, they will run out of the less reliable components, and at that point it's game over - It's simply not possible to support them any more.

Now, I expect that Garmin ordered a lot more parts for the G1000 than they did for a G5, for example... But there is an expiration date on all electronics.
 
Yes... But that requires either the G1000 NXi, or a software update to the G1000. Since the G1000 software has to be approved by the aircraft OEM, and there's not much incentive for them to do anything for their older birds, I think only Daher (TBMs) and Cirrus (?) have done so. ….
There’s at least one Mooney in the US with it.
 
A non-NXi? Where?

Don’t know it’s NXi or not; I believe it’s an Acclaim.

 
So here's the conundrum.
No conundrum or expiration date. Basically, Garmin has guaranteed Bell they will support the 407 G1000 in perpetuity. Its also my understanding there are one or two other OEMs with a similar deal. I think in the case of a 407, those who have a conundrum are the ones with the original analog panels with Litton indicators.

I think the reason Bell went the extra mile to provide a G1000 retrofit kit back to 407 S/N: 00001 was the Litton indicators were on the sunset list and they only want to support the G1000 in the 407. So its those owners who need to make a decision sooner than later on what route they need to take. Regardless, I’ll stick to my statement the G1000 will be around for the foreseeable future based on what I’ve learned and have recommended.
 
No conundrum or expiration date. Basically, Garmin has guaranteed Bell they will support the 407 G1000 in perpetuity.
No such thing in electronics, save replacing the whole kit with something that fits in the same space and does the same thing 20 years down the road. But maybe that's the commitment they made - our screen, even if replaced and on a different platform, will fit in the hole and do the same thing.
 
No conundrum or expiration date. Basically, Garmin has guaranteed Bell they will support the 407 G1000 in perpetuity.
There is no guarantee, contract, or other agreement that can make electronic components appear out of thin air. There is an expiration date... We just don't know what it is. Given the limits of economics, they may have gone with a 30+ year projected supply, but I can't imagine they'd be able to do more than that... And they really don't know what the weak link is yet so what was a 30-year supply might quickly become a 10-year supply.

I think @Steamflyer is probably right that things like the NXi upgrade will be required eventually. That could still be viewed as "supporting".
 
Don’t know it’s NXi or not; I believe it’s an Acclaim.

Interesting... That's definitely not an NXi (all caps on the softkey labels) but it's a flightstream 210, not 510, and he says it was configured solely for flight plan transfer (no ADS-B In streaming of weather and traffic to portable devices).

There’s another thread over there as well talking about one done in Europe that gets into the technical aspect of why weather/traffic isn’t transmitted.
 
But maybe that's the commitment they made
That could still be viewed as "supporting".
I think we’re splitting hairs here. In 2011 the 407 was offered with the G1000H which was originally an option, then quickly became the only option. Around 2017 the G1000H NXi became standard equipment and its my understanding the G1000H NXi will eventually replace the original G1000H as needed but the G1000H support has no defined end date. And it was after the G1000H NXi was released that Bell developed the retrofit kit for the legacy aircraft to bring them into the G1000 fold per se.

What took me down this rabbit hole was there were several pre-NXi 407 owners and one legacy analog 407 owner who wanted to upgrade their avionics. Suffice to say if the G1000H is serviceable any upgrade is on your nickel. So if Garmin plans to support the G1000H for the earlier 407s for an undetermined time I see no reason why they wouldn’t provide the same support for existing G1000 owners either given the hardware is the same.

Yup, in two weeks I'll be flying mine from Atlanta to Glacier and Yellowstone NP's in Montana/Wyoming, Vegas, the Grand Canyon, and back home. And it will fly like a dream, on half the gas of an SR22. Might take me 20% longer, but I'll be statistically more safe as well.
 
The original question was "why so many for sale?"

Like everyone, I only have suspicions. Severely limited part availability adds to general mx wait time and cost frustrations; 'why do I own a million dollar plane I can't fly?' Even living in Duluth the part availability is almost nonexistent. Add to that the frustration of repack wait times...

I don't really buy the "everyone is upgrading" answer because that would require the planes for sale numbers to equal new version production quantities.

I suspect that Cirrus owners are overrepresented by vanity purchases that don't actually get used that much. I personally know more than a couple of dot com millionaires who bought-then-soon-sold or bought-but-rarely-flew theirs without accumulating many hours, but that's even more handwaving.

On the question of safety I am perpetually frustrated by the lack of readily comparable data on the subject.

Well, there is data available. Just out of curiosity, what constitutes "many hours"? Just what I recall reading around 70hr/yr is average. 50 or less is low or what I'd consider "not many". 100hrs/yr or greater seems to be the goal.

 
My hunch is based on anecdote; I'd say under 50/year but I definitely wasn't checking logbooks!
 
Yup, in two weeks I'll be flying mine from Atlanta to Glacier and Yellowstone NP's in Montana/Wyoming, Vegas, the Grand Canyon, and back home. And it will fly like a dream, on half the gas of an SR22. Might take me 20% longer, but I'll be statistically more safe as well.

Agree to disagree. I'll take the parachute, better climb capability, better de-ice/anti-ice options, in some cases, better autopilot, as well as better overall A&P support. That's me.

Diamond itself I think treats the DA-40 as a "stepping stone aircraft" to get you into their more luxurious options (think DA50 or 62). A Lifestyle rep once told me that a lot of the DA40 purchases are folks without a PPL. Dead serious. They buy it to learn on it, flip it, and then go buy a higher performing Diamond. :shrug:

I have a process to estimate the average annual flight time for homebuilts involved in accidents. It takes the date of the accident, subtracted by the manufacture date of the aircraft, and computes the annual flight time based on the total time at the accident.

I call it "RRSM", for "Ron's Really Stupid Method." Because it IS. It assumes the aircraft first flew on the first day of the manufactured year. However, I tend to believe that it smooths itself out over time...some planes fly on the first day of the year, others on the last day, and the assumption is that it'll average out.

The FAA Survey says that homebuilts fly ~50 hours per year. RSSM says 50.8. Coincidence? Maybe.

Anyway, I use the same sort of database on process on Cirrus accidents from 1998 through 2022. I only include accidents where the manufactured date and the aircraft total time are available. That eliminates more than half of the total from the process.

Here's how the results come out...

The median is about 182 hours per year.
