Cautionary tale about Internet instruction

That subject title should get your attention, because yes, this post is about an accident. In recent weeks we published the first of our planned series The Approach, which is a series of articles about backcountry flying strategy, and we started off with a technique for attitude flying that has the potential to let you achieve such a steep glide slope that you can sink at a very high rate on final.

Adoption of this technique for individual pilots and their aircraft and their personal abilities is a huge variable, one that can only be addressed by a live human instructor in the cockpit. Please do not go out and try this stuff by yourself in an environment where you can be hurt or damage your equipment. We publish these articles to open your mind and provide inspiration about what is possible, but make no mistake-- pushing into new, uncharted waters in your personal skillset has risks. Go out with a qualified instructor, and even then, be careful. Reading about it on the Internet is no substitute.

I'll let the conversation about the details pick up from here, but please remember that safety and preservation of property trump bragging rights. Some risks aren't on the menu when you're a hundred miles from assistance.

I'm going to respect this person's anonymity (I made a few select edits), please do not try to identify them here, that's not the point, just take the message and the outcome for what it is. The person who wrote this will definitely read your responses.

Edit: I'll add that I'm not posting the preface above to take anything away from the pilot's comments. They seem fairly experienced, in fact. However, I do want to revisit the message and the purpose of The Approach article, which is to provide a very broad technique for flying a pitch attitude that provides an appropriate AOA that will result in shorter, more controlled landings when appropriate. The message is NOT to get as slow as possible, or to approach as steeply as possible. Those are certainly possible, but the ultimate outcome should be a safe approach, not riding the ragged edge, or getting behind the power curve. Perhaps we will edit the article to more strongly emphasize these caveats.

Hi all,
I want to speak out a warning to try these kind of approaches!

But let me explain.

I have by far not the flight hours Patrick has, in fact I have 1050 hrs TT. 250 Hrs in gliders. 350 tailwheel and the rest on T41s, 172s incl. RG's, Pipers and Huskies. I think I am a decent pilot and since I finished my AC ( 260HP) last year, I have flown 200 hrs most of it cross country and in the backcountry. I landed at Cabin Creek, Wilson Bar, Sodier Bar, Deadwood Reservoir and lots of other strips, always the way I learned it with an approach speed 1.2 or 1.3 of Vso. Because it is an experimental aircraft I could not rely on a POH but had to fly those speed myself. From that I know that Vso of my AC is 37ktn add 20% to 30% and you are in the vicinity of 45 to 49 ktn. (Very similar to Patricks M7 I guess) With full flaps I had never a problem to get into one of those fields and additionally I could always slip the aircraft. (Yes, I am coming from a glider background, I have no problem to slip an aircraft) Those technics worked for me all the time. I could stop my AC in 300 to 400 ft and thats always way shorter than one actually need on those strips. (i.m.h.o. those short field landings are highly overrated because you need to get out of those fields again and you usually need more take off distance than you need to land! )

So a week before New Years Eve I did read Patricks article and thought that is an interesting thing worth trying. I went out to my airport and flew a some stalls the get my speeds again and then tried his method on our dirt RWY. And... it worked! My landings were short, within 300 feet.

I noticed that the elevator authority was almost gone and that you need that power burst Patrick is talking about to get at least some authority on the elevator in that transition from decent to flare. But..... It worked.

Until December 31st. I was out again to practice and this time I came a little to short. We have a cross RWY and that RWY has a drainage ditch.

Of course I was eager to shorten my landings even more and when I pushed the throttle in for the power burst, the RPM increased, nose came up but the AC did not stop sinking.

What happened? For some reason I had lost my altitude before I had overflown the ditch. On the approaches before, that power burst did get the nose up (tail down) and the aircraft settled down in an almost trheepointer with a fully stalled wing. This time, the ground wasn't there and although the nose came up, the aircraft did sink slightly into the ditch. The rest happened fast. My 26" Goodyears hit the edge of that ditch. The right gear leg was torn out of it's mount. When the aircraft began pointing the nose left, the left gear collapsed and the prop hit the ground and disintegrated.
The aircraft came to a stop and that was by far the shortest landing I have ever made. :-(

We all know that similar situation can happen everywhere in the backcountry. When you approach Angle Point, UT or Soldier Bar, ID you actually land on a carrier. Before you reach your RWY the ground is a few hundred feet lower than the actual RWY. You might get a downdraft or something or you don't have a straight horizon, like approaching Cabin Creek, to check your wings and then you have no reserve! You and your aircraft are doomed.

I was lucky! It happened at my home airfield help was instantly there and I walked away! Except a big dent in my EGO and a few thousand buck to repair the aircraft I am fine. For strips like Deadwood Reservoir or Mile High, I doubt that this method will work at all because you will not have enough speed to follow the ascending ground. So my guess is you will impact like a stone.

But I also learned something.

If something works for you! Don't change it!

I don't blame somebody except myself! I was stupid enough to depart from that principle.

And again. Shortfield landings are overrated and they push you into some kind of dangerous competition which is complete unnecessary!

Fly safe

Re: Cautionary tale about Internet instruction

Well I have to say full points to Mr.X for sharing, and I have to say how sorry I am for his AC but glad that he is ok.

I too am a new pilot, 250 hours, and read this article with the video. At first I thought , that is SO not for me yet. I have 145 hp 170 and can land it consistently way shorter than I would dare to get out from. Almost always three point and I can hit my spot pretty consistently.

However yesterday I was up at 6500 ft doing some slow fight and stalls and thought about the video again. I found that I could get the aircraft nice and stable using the wing to horizon angle at about 40 mph which is so much slower than I would ever approach and control sink with throttle. I still had good aileron authority. It was fun to play with and maybe helped me learn just a bit more about my plane.

No way I am going to put this into any approach for now though.

Once again - sorry for the plane.

Re: Cautionary tale about Internet instruction

Gonna go out on a limb and say that "pitch for airspeed power for altitude" is nothing revolutionary. The video was excellent and describes a slow steep approach well, albeit nothing new to many pilots.

IMO it is a big stretch to hang your accident on anyone else, especially a video online or short landings in general. Maybe shooting for the middle of a runway with this new to you method would have been a bit wiser than a spot with a drainage ditch just before.

Short landings are not required for big paved runways, other places they are. I've heard this argument from others and discount it completely but especially due to one scenario any pilot may encounter; would u prefer to be proficient on short landings in ur aircraft when the engine quits and the only option is a short tight spot, maybe not the best time to learn proficiency? Nah just stick with the I don't need flaps and brakes are expensive theory ;)

Sorry ur aircraft got tore up, total bummer. Just giving an honest opinion for whatever that's worth...

Re: Cautionary tale about Internet instruction

I would a gree that if you are comfortable then keep doing it, but keep an open mind. If you push too much bad things can happen. Being that I fly an aircraft that pretty much nobody else flies in the backcountry it has been up to me to figure out how to finess the airplane into places that others could only dream of taking a Mooney. The key thing for me is to set up an area for practice that I know is safe. Instead of the threshold it might be the 500ft markers instead. And once I get something down I perfect it, I don't try and push it harder and harder. That way if I come up short, or having something I don't plan on happen.... I won't damage the bird. Either way, we live and learn. Luckily the airplane can be fixed and you learned a good lesson. I hope your bird is back up soon and you're at it again!

Re: Cautionary tale about Internet instruction

Maybe instead of/in addition to a list of tailwheel instructors around the country we should develope a list of STOL instructors in various parts of the country? Maybe a list by those instructors of what specific aircraft they are (very) proficient in?
The pilots/ members here that use those instructors could recommend/rate/critique the individual instructors on the thread?

Just thinking out loud here. Top notch instructors are PRICELESS, besides being cheap insurance when exploring your aircraft's flight envelope.

Sorry about your misshap.

Afterthought: I wouldn't want BCP to be exposed to partial liability for a mishap. A disclaimer on thread might be (?) sufficient?

Re: Cautionary tale about Internet instruction

I’m interested in the unexplained sinker in this account. My airplane has a nasty tendency to suddenly drop like a stone out what had been a stabilized descent on short final. This happens only occasionally, and I’ve not been able to predict it despite 800 hours in this airplane (’76 206).

I suspect that it’s caused by the combination of Horton STOL kit and flap gap seals, as the stall break is sharper than the typical Cessna mush. Anyway, I have to assume that it will happen and be ready to add power fast. I also need some extra room past the threshold to reduce the risk of coming up short. I’ve thought about taking off the gap seals, but don’t want to make the airplane any slower.

Anyway, my takeaway is that it takes more than a few flight tests before you know what can/may happen and how to deal with it. Combining mods can be tricky. I wouldn’t add gap seals if they weren’t already installed. I practice short landings because I think it’s good emergency preparedness and keeps me sharp, but I prefer aiming for a spot past the threshold unless it’s a displaced threshold. I've been into all of the places mentioned in the OP except not the Big Creek 4. It's not necessary to touch down exactly on the threshold of any of them, IMO/experience.

Re: Cautionary tale about Internet instruction

Regardless, here's a guy (gal?) who weathered a pretty bad outcome, and then used the experience to help educate others, rather than turning around and suing somebody. That's remarkable in this day and age. I wish that kind of personal integrity was the norm, rather than the exception anymore. Possibly it still is among aviators. I'd like to think so.

My hat's off to the pilot, and best wishes for a fast return to the air.

Re: Cautionary tale about Internet instruction

Good one Z.

There aren't too many instructors around comfortable enough to let you get way behind the curve because they cannot catch it if you screw up.

I am not a fan of this approach style. Done it, and have seen it done way better than I can do it. If you use this method and get behind it just a little bit, find a sinker, or the neighborhood dog, bear, deer, whatever runs out in front of you, see that log pointing at you that you missed on the low pass, just make sure you know ahead of time that you're taking what's in front of you. If you have a ton of power, then the chances of success are way better.

A mentor of mine flew every approach hot with lots of energy on touchdown. Used plenty of brakes up, and bent his share of metal too. Using his method, he can land a 180 in places that will make the super cub bullshitter pilots go crying home to momma.

Background:

Off field operations with passengers in loaded airplanes for several years. Didn't do it nearly as much as my dad did, and by no means an expert.

As the OP stated, you still have to take off.

Cautionary tale about Internet instruction

We have many disclaimers around the site on registration and on every article page. I don't grant pilot certificates nor do I sign people's logbooks. BCP is purely for entertainment and pilot fantasy masturbation.

The first pilot to sue me for claiming that I or anyone on this website made his decisions for him will experience the full force of my attorney and my personal crusade to see their certificate revoked for allowing a website to override their PIC authority, in addition to not getting shit because I'm a fucking pauper.

Edit: perhaps a bit melodramatic.

Re: Cautionary tale about Internet instruction

There are a lot of ways to skin a cat, and this has been a respectable tool for some folks in some airplanes for a long, long time.

But- I saw one vocal proponent of the technique demonstrating it in the backcountry in a Citabria many years ago, with several folks other than myself watching, only to end up in a slight pride-bending situation...all with perhaps 1500' or more of beautiful runway left ahead of him. All of us less legendary flyers eventually got back to their evening supper and continued on with our vacations even as the other guy could not. It made an impression on me.

When I have tried something resembling the "falling manhole cover approach", I do indeed get to land a bit shorter, and hitting the desired LZ point required a bit less finesse, although I'd have to add more emphasis to 'hitting the LZ'. It was a lot of fun when I was more into low, slow maneuvering.

But I've never owned a plane where the landing required as much room as the takeoff...and not by a long shot up higher. And I've never flown the backcountry for a week at a time when I didn't have at least a few approaches where a low-margin-by-choice approach might have been plain silly.

Using as much of the available runway to land as needed to make the event as boring as possible for myself and pax generally requires roughly what the the POH says usually, and sometimes less, aside for saving the brakes. And 99.9% of the time, making conventional short field landings will never trump the runway I need to go back home on takeoff.

So I guess for me it was more a choice between 'art and fun' or just being practical. The slow steep "falling manhole cover" arrival performs as advertised, but I can't see why it is more than just another tool in the bag to have fun with for most folks who use the backcountry.

He clearly did not "hang" his accident on anyone else. I don't even know where you got that from. He clearly states it was all on him.

I agree 100%. The OP impressed me as someone who was curious about a technique, went out and tried it, took full responsibility for the unfortunate outcome, and was willing to share it with the rest of us so we could make our own decisions about it. I appreciate the willingness to put ego aside and let the rest of us benefit from the experience (Lord knows, we've probably all had "experiences" of our own), and I appreciate even more his candid recognition that he's the one who was responsible for whatever happened.

Bummer about the bent metal, thanks for contributing the info so we can all learn together, and I hope she's flying again soon.

Re: Cautionary tale about Internet instruction

Corefile, I was referring to this statement by the original poster:

"And Again. Shortfield landings are overrated and they push you into some kind of dangerous competition and are complete unnecessary"

My communication skills may be lacking and perhaps my statement was a bit of a "stretch" too ;)
The part where the OP says it's all on them doesn't jive as they also made that statement, which IMO is totally bogus. It takes away from the "it's all on me part" by putting blame on this landing competition they refer directly as being pushed in to?

If I sound like I am talking down to anyone that is not the intent, I have dumbass attacks daily, some bend more metal than others! No hate intended homie, sorry if that's how it came across :(

I was out flying the day after you posted that video via BCP YouTube, and tried to use the angle as described. It didn't work for me in my Bearhawk.

I guess the aerofoil on the Bearhawk does not lend itself to that sort of approach angle and power combination, you'd never hit your airspeed consistently enough. Too much flaps / drag maybe?

I find it better to have the wing roughly level with the horizon, with a fair touch of power to keep it from sinking like a rock... 45kts approach speed and just on the edge of the AOA alarm (1.2 Vso), unless it's dead calm and 40kts deeper into the AOA alarm becomes a realistic option (about 1.1 Vso). Forward visibility is better that way too. But we do have problems with the flaps washing the elevator off, so you lose pitch authority at full flaps. I am installing VGs as it can be hard to time the burst of power.

And to the AOA nay-sayers - I have no idea what you were talking about! The audible AOA warning is a God-send. It always lets me know when I start to push my luck, no matter what the aircraft weight or wind is doing. I find it especially good in gusty winds as it lets you know how close to critical AOA the gust takes you. 2c

Re: Cautionary tale about Internet instruction

My landing technique isn't the greatest but I can get in and out of the places I want to go to.

I think that no matter which technique you use it's probably a good idea to figure out what are the weaknesses of your particular method and plan for them. Plan your approach with a margin so that you can deal with whatever emergency might crop up having to do with the weakness of your particular method. Man, I'm having a hard time putting that into words. Hopefully y'all get what I'm trying to say.

I'd say you're doing exactly what the article and video suggest-- for your aircraft. You're paying attention to AOA. I'd say that the technique is an approach (no pun intended) to flying the wing, and the apparent positive angle of the wing surface above the horizon is only an example. I would expect it to vary for every aircraft and airfoil.

As for the Bearhawk and the Riblett airfoil that it uses, I find this surprising that it doesn't tolerate the higher AOA well. I have only the time in the Bearhawk that Blackrock has treated me to, but I did do some slow flight and a stall. It was mellow with no apparent hard break, so my assumption would be that this technique would work well, but that it would be easy to get into a super sinky situation that's just not practical.

Anyway, I can't speak with authority, but as you know, I have a vested interest in this particular aircraft's behavior.

Your post raises few interesting points -

The Bearhawk aerofoil actually isn't a Riblett, it's NACA 4412 I think. Slightly modified from memory - but Bob modified it I think, not Harry Riblett.
Bob started using Harry's designs after the Bearhawk, so the Patrol and LSA use a Riblett modified NACA.

The Bearhawk wings LOVE to keep flying, at high insanely high AOA it's still hanging in there.
In fact, it can tolerate more angle of attach than I can approach to land. Call me chicken!

Also interesting - the NACA and Riblett aerofoil Bob chose are basically a glider aerofoil for all intents and purposes, I was told (by Bob I think). So he said using the flaps is important to get landed without a long flare or bounce etc. because the wing loves to keep flying at low airspeed.

I just find that a very high nose attitude or very high sink rate on landing approach to be a real dog, it's wallowing around and you can't see jack, or it's racing towards the ground and all that downward momentum takes time to bleed off in the round-out. And to boot, the airspeed is hardly any different to what you can fly with wings level to the horizon - so I just don't bother. Not yet.... I have more 'sperimenting to do at altitude with the VGs.

Re: Cautionary tale about Internet instruction

OH boy, I am really sorry about the damage to your plane. I really appreciate the way you "fessed up" and brought this issue out for us all.
I have used this technique in my Stinson and it works fine but I found that I had to be really on a good day. I wouldn't even try it unless I had been doing a lot of low and slow so I was tuned up good. My plane has quite a lot of power for it's weight so it will recover if I get behind in this maneuver better than some but it would definitely be tougher with low power.

When I worked up to doing this the first few times I picked an altitude of 1500 AGL and made numerous approaches to "land" at that altitude. I then worked into it a bit at a time at ground level.

Anyway, thanks for the lesson and again sorry for the damage.
