Small craft midair collision near APA

Wed May 12, 2021 4:53 pm

UPDATE: Initial reports indicate that 2 planes collided midair over Cherry Creek State Park property just south of Belleview and Peoria. One plane crashed here with no injuries or fatalities. The second plane landed safely at Centennial Airport with no injuries. Updates to follow

Is that a Cirrus? It's tough to tell in the photo, but it looks like a parachute might have saved them.

It's a relief to hear no one was injured, let alone killed.

Looks like a Cirrus involved and no reported fatalities. CAPS may have saved the day again.

Comments in that tweet says it was Key Lime (probably KG970) vs the Cirrus (based on FR24 playback, I assume N416DJ)

Glad no one was hurt.

I drive by Centennial every day, and they keep that pattern stuffed FULL. Surprised this doesn’t happen more often there.

Definitely a Cirrus. And you can see the parachute deployed behind it. What I can't see is the rudder. Otherwise the plane looks mostly intact. If it did in fact lose it's rudder, there is not doubt that the CAPS saved their life. As a Cirrus pilot myself, you always love knowing that you have that option.

Just saw the photo of the Key Lime Metro at APA... 2/3 of the fuselage barrel, a few feet wide just forward of the tailplane is gone. Amazing it stayed intact, and incredibly lucky nobody was sitting back there. Would definitely been a fatal and quite a mess... will see if I can locate a shareable version.

KLA's HQ is at APA, but they have no scheduled service from there. So likely no passengers.

That SWM is probably only used for boxes anyway. I don't think they are running their Denver area-GJT pax flights right now.

Safe to say that that Metroliner is a loss. But I'm amazed that the plane was able to get on the ground in one piece. At least Key Lime Air can salvage it for parts and then scrap what cannot be reused.

Listened to the recording. Cirrus was cleared to 17R - Metro was on another tower frequency for 17L. West controller gave Cirrus a traffic advisory for the Metro and they called "in-sight". Controller was asking him not to overshoot final right before he saw the chute deploy. Looks like the SR-22 took it too wide.

Thanks. Those new (to me) photos in the report are amazing, Quick note that though the collision happened at 6400 feet, the airfield is at nearly 5900 feet so only 500' above ground.

This is the tower controller working the Metroliner - the Cirrus was on another frequency - not sure how to link that one. Starts about 23-minutes in.

It's on LiveATC. Just listen to KAPA Tower (Primary) and KAPA Tower (Secondary #1) between 1600-1630Z. Should start around the 22-23 minute mark.

APA runs two frequencies when the pattern gets busy (controller was clearing someone #5 for touch and go); one for the short 17R and one for the long 17L used by departures and IFR/jet arrivals. You can hear the 17R controller warn the Cirrus "do not overshoot the final" before he suddenly asks if they require any assistance. People overshooting the final at APA has been an ongoing issue; I guess it finally resulted in an accident.

N416DJ is under Independence Aviation out of KAPA...based on the track, it looks like they went North for a discovery flight along the mountains. 6DJ is one of the planes included in their discovery flight promos.

Low wing aircraft making a wide right turn to final...likely lost sight (or never sighted in the first place) the Metro coming in fast from the left. Not the first time this has happened and it won't be the last, but what a great outcome!

I too thought about how the Cirrus couldn't have been more than 500'-700' above the ground. Does anyone know the minimum altitude needed for a safe parachute deploy?

In that plane, the Cirrus manual states safe deployment is between 600' and 2000' AGL but you may deploy less than 600' AGL if no survivable alternate exists.

Video of the Cirrus floating toward the ground shows the aircraft is very much intact. Maybe the landing gear(s) is missing...it's hard to tell due to the video quality. Both wings are intact, so I'm assuming the Cirrus' landing gear is what hit the fuselage of the Metro.

In the ATC audio, the controller warns the Cirrus aircraft not to to overshoot the turn, but has to interrupt himself to ask if assistance is needed (presumably because a parachute was spotted).

Incredible outcome. Every one of these recordings reenforces my respect for controllers at fields large and small.

It’s clear the Metroliner pilot didn’t know the extent of what occurred- probably for the best. On the recording he calmly reports that he’s declaring an emergency because it “looks like the right engine failed”... understatement of the year. Imagine his shock when he got a look at the damage.

So glad everyone is ok. It could have been so much worse.

Clearly a navigation error but people's lucky stars were shining that day.

Do I see correctly that there's not only fuselage damage but also a piece of rudder missing? The lower most forward corner?

Yes, in addition to the damage to the fuselage, there's a small chunk missing from the leading edge of the tail of the Metro.

Based on some of the photos, it looks like the Cirrus nicked the top of the Metro and "folded over" (for lack of a better term) a large piece of the fuselage to the left. The damage looks impressive, but most of the fuselage material is still present and attached to the aircraft.

That Metro pilot was very calm, even after he realized what happened and asked to taxi to Signature.

And this may be key. The runways are less than 700 feet apart. If you have a tailwind on the right base to 17R, you have to be on your game. The track log indicates that the Cirrus was really booking on the base leg (over 150 kts).

Would either of the aircraft involved be TCAS equipped? I would imagine that the Metro would have TCAS, but what about the Cirrus?

I can't speak for the Metroliner, but all Cirruses have TCAS. It is one of the reason I fly them. State of the art GPS with coupled Auto Pilot. Parachute. TCAS. It's what set them apart in their category of aircraft.

Is it TCAS or ADS-In which provides TAS service but no RA. If TCAS equipped there should have been a RA unless the Cirrus was below the min height required for an RA.

In that plane, the Cirrus manual states safe deployment is between 600' and 2000' AGL but you may deploy less than 600' AGL if no survivable alternate exists.


The demonstrated minimum AGL is 400 feet. Usually at 500' we'll call out CAPS available as we climb out as a reminder that it is an option. That being said, if you got NO option, even below 400' I'd still try it. There is no demonstrated spin recovery on a Cirrus. So if you are in a spin, you pull the chute. If you are under 400', it just probably isn't your day.

When I watched the video, there is a nuance that I think most would not recognize. The oscillation that was happening as it impacted the ground shows a very low deployment. It likely would have flattened out if it had a few more 100 feet. Because of that oscillation, this likely was a bit harder of an impact than normal. That being said, if you didn't have the CAPS, or didn't use the CAPS, or even waited a few more seconds, you'd have a lot worse situation.

Also, someone said they were doing 150kts on base leg. I am sure that was ground speed and probably wasn't airspeed. But the CAPS shouldn't be deployed above 133kts. Again, if you have no option, you do it anyways. But it benefits you to get slower (with out stalling of course) if you have that option available to you. Being that close to max speed, at that low of an altitude, with that minimal amount of oscillation, really shows just how amazing the CAPS really is.

I had to look that up. You're right that it is just TAS with no RA. But it is still technically TCAS. It's just TCAS-1 (no RA) instead of TCAS-2 (with RA).

I have an uncle that was a sales representative for Cirrus many years ago when the parachute system was new. He was careful to emphasize that it is truly a “last ditch” option. Basically you can hit the ground at 200 kts or something less than that, how much less and whether you survive is an open question.

First, before making light of the situation, this is borderline miraculous that anybody survived this.

Now...

Can we say that Fairchild offered the Metroliner with a convertible option?

This is not true. It may have been how they sold it back in the day when they were getting all the critique from Cessna and before it had proven itself in the real world. But they specifically train us now NOT to think like this because there were many cases where there was reluctance to pull it that would have saved lives.

While it certainly isn't your FIRST choice, and you should still try and see if there is an acceptable place to land if you have effective control of the aircraft, there should absolutely not be any hesitation to use it - especially in particularly grave situations (spins, icing, collision, etc...).

It isn't like hitting the ground at 200 kts. It is the G-impact equivalent of a 15 foot fall. It's essentially the equivalent of being strapped to a chair and thrown off the single story house roof but landing on all for legs of the chair. Certainly not something you want to do, but also not NEARLY the equivalent of hitting the ground at 200 kts.

Also, regarding whether you survive is an open question: it absolutely is not an open question. There has been no deaths related to a CAPS deployment when used within the parameters (less than 133 kts, above 500'). There have been 122 CAPS deployments, with 103 of those resulting in no deaths. Out of the 13 fatal events, all but 3 of them were because it was attempted to be deployed too low (below 500'): https://www.cirruspilots.org/Safety/CAPS-Event-History

I have an uncle that was a sales representative for Cirrus many years ago when the parachute system was new. He was careful to emphasize that it is truly a “last ditch” option. Basically you can hit the ground at 200 kts or something less than that, how much less and whether you survive is an open question.


This is not true. It may have been how they sold it back in the day when they were getting all the critique from Cessna and before it had proven itself in the real world. But they specifically train us now NOT to think like this because there were many cases where there was reluctance to pull it that would have saved lives.

That makes sense. Yeah I’d have to get the details from him but this would have been in the 1999-2000 timeframe so messaging may have been different. And my comment was specifically in relation to activations below 500’, but from this incident and from the list you shared, it looks like there have been successful activations even at below spec altitudes (I saw one 300’) so I don’t doubt the technology at all.

I too thought about how the Cirrus couldn't have been more than 500'-700' above the ground. Does anyone know the minimum altitude needed for a safe parachute deploy?

In that plane, the Cirrus manual states safe deployment is between 600' and 2000' AGL but you may deploy less than 600' AGL if no survivable alternate exists.


The demonstrated minimum AGL is 400 feet. Usually at 500' we'll call out CAPS available as we climb out as a reminder that it is an option. That being said, if you got NO option, even below 400' I'd still try it. There is no demonstrated spin recovery on a Cirrus. So if you are in a spin, you pull the chute. If you are under 400', it just probably isn't your day.

When I watched the video, there is a nuance that I think most would not recognize. The oscillation that was happening as it impacted the ground shows a very low deployment. It likely would have flattened out if it had a few more 100 feet. Because of that oscillation, this likely was a bit harder of an impact than normal. That being said, if you didn't have the CAPS, or didn't use the CAPS, or even waited a few more seconds, you'd have a lot worse situation.

Also, someone said they were doing 150kts on base leg. I am sure that was ground speed and probably wasn't airspeed. But the CAPS shouldn't be deployed above 133kts. Again, if you have no option, you do it anyways. But it benefits you to get slower (with out stalling of course) if you have that option available to you. Being that close to max speed, at that low of an altitude, with that minimal amount of oscillation, really shows just how amazing the CAPS really is.

Vpd is max demonstrated parachute deployment speed. It isn’t a hard limit like Vne on the airspeed indicator. So just because the POH states it’s 133 (135 in the G2), it doesn’t mean that it can’t be deployed any faster, like how the max demonstrated crosswind is 21 knots. It’s just what was “demonstrated”.

Also: the ground impact force is equivalent to a 10 foot drop, and a roughly 1,500 fpm descent rate when it’s coming down with it. Cirrus seats also have a crushing honeycomb design which helps absorb some of the impact force when the plane hits the ground after CAPS has been deployed.

Really amazing that no one was injured. Having said that The metro should just need to be buffed out. :D

Absolutely incredible! I cannot for the life of me figure out how that damage was done to the Metroliner and didn’t take out the entire tail section. I’d love to see exactly what orientation that Cirrus was in to be able to carve out a chunk like that, but manage to leave the tail mostly untouched.
