NTSB Prelim Report Analysis: Lake Placid 177RG Crash killing Richard McSpadden and Russ Francis
I provide an early analysis of the NTSB Preliminary Report on the crash of a Cessna Cardinal (177RG) that killed the beloved Richard McSpadden and former NFL star Russ Francis.
From the information in this early report, we see where the NTSB has initially investigated. We already knew that there was an element of engine power loss but that begs the question, why did the engine lose its power in the first place? We dig into that topic in detail and explore any possible lessons that could be learned here, even before we have the full results of the investigation which could take years to complete.
Based on the early information in the NTSB report, we can discuss the what-if's about engine failures and how we can detect early warning signs of possible engine failures. That's not to say with any certainty that any warning signs were apparent here to these pilots in this particular accident, because we still conclusively don't know what happened to the engine. But there are real dangers and real scenarios worth discussing to improve the safety of our future flights whose lessons we can take to heart now, immediately, as we comb through any of the possibilities that led to this tragic outcome.

    No, why the engine failed isn't the main question, numbnuts. The question is why they tried to make that dumb impossible turn back to the runway. Engines fail. Every pilot, every moment of the flight, should be ready for that to happen. And your entire video here is completely speculative and unsupported by the evidence in the NTSB preliminary report. It is, basically, storytelling. You aren't even being internally consistent.

    My thoughts Not a pilot...They're running a rich mixture for a faster run-in ? That seems fraught with problems. There are other ways to do it. Royal Enfield Motorcycles (I think) use thinner oil for the run in to accelerate wear. New or re-bored Motorcycle and car engines have the luxury of not needing full power straight away. Do they not bench run in these aviation engines at all? 36 hours ...should be run in? 36@50mph(equivalent for cars) is 1,800 miles These engines sound behind the times. From the mid 90s motorcycle engine can be thrashed straight out of the crate. They don't last as long without the careful run in but they're ready to go immediately and don't really overheat. And they're high performance- my suzuki is 1000cc and 160ish bhp. Sad loss. Apparently engine failure on take off is the worst.

There are gobs and gobs of data available right now so the lessons to other pilots can begin now. We should not throw up a roadblock to learning just because someone passed away in an accident. If it were me that had passed away in an accident, I would hope others would immediately learn from my potential mistakes and bad decisions and not repeat them. Not only can we learn lessons immediately from accidents but we can also provide closure to people that are desperately seeking relevant and valid information about an accident. There is an extreme shortage of useful information in the media after these crashes.

    Flaps are so misunderstood. Most pilots think of them as high lift devices that reduce stall speed. While that's true, you can also think of them as camber modification devices. Wings with higher camber shift all speeds lower - Vx, Vy, best glide, best endurance, and best range. Even if they add drag, there may be performance benefits utilizing small amounts of flaps. It's really hard to tell without doing analysis of the modified drag polar or flight testing. And manufacturers of light GA aircraft simply aren't going to do flight testing with partial flap settings except where it's normal like flying for best angle-of-climb. Also, giving something else for pilots to think about in an emergency is probably counterproductive. When I used to fly C152s in my much younger days, on one high DA day I decided to experiment with partial flaps in a climb. I found that adding 5°-10° of flaps improved my climb rate significantly. But anything compared to nothing was an infinite improvement :-) As a pilot and instructor, maybe it's proper to complain about their use of flaps when the POH doesn't call for it. However, as an engineer with a background in aerodynamics, flight mechanics, and aircraft design, I can't fault them without knowing more information. There's a chance they would have fallen even more short had they not used partial flaps, for example. With the engine making partial power, you could make an argument to fly at a speed where less power is required. This is obviously at lower speeds, and partial flaps makes the wing more efficient in terms of power required at lower speeds even with increases in drag up to a point. My advice is, if you're a student, follow the book. If all you do is chase $100 hamburgers, follow the book. But if you're in a constant learning mode like me, go up to a safe altitude and experiment some to understand the true capabilities of your aircraft and also learn your capabilities and limitations as a pilot. Just my $0.02.

  • @ConvairDart106

    I know of no other pilot besides myself, who never departs straight out on departure over inhospitable terrain. For me, this accident is the result of bad decision making. My home airport is located with the city to the east, and surrounded by forest on the three other sides. I climb up to 3,000 feet before exiting the airport environment, and circle down into the pattern upon return. We are supposed to fly as if we EXPECT an engine failure at any time! 99% do not fly with that mindset, and will suffer the same result if this happens to them in the future. I climb until I can assure making an open area in my chosen direction, and will only depart the airport when I know it is safe to do so. Staying in the pattern for just one minute more for an extra 1,000 feet of altitude does not cost that much, and is the cheapest insurance you can buy with one gallon of fuel. Your decision decides the fate of everyone on board! Choose wisely! I have been flying for 40 years, and have had two engine failures. The first one resulted in a restart at 3,000 agl. The altitude gave me plenty of time to go through the checklist. The second one found me having to shed altitude in order to make the runway.

    • @MalibuMikeCFII
      @MalibuMikeCFII ปีที่แล้ว

      Allow me to play devil's advocate for a moment. For many airports, and/or many airplanes, there is typically going to be a vulnerable minute or two for departures simply because the area might be heavily congested or as Richard himself demonstrated in his video publications (e.g. for high performant aircraft), the impossible turn is truly impossible. To make a blanket statement that unless people fly the way you do, they will suffer an off-airport landing, is a little far-reaching. For GA, the fatality rate in the U.S. has been hovering around 1 in 100,000 hours the past couple of decades. I tend to believe the bottom 5% of pilots weighs that statistic down; I want to be in the top 5% to be a couple more orders of magnitude safe. You are striving for the same thing. However, with modern-day engine monitors and subsequent data analysis capabilities, oil filters, and oil spectral analysis, under most circumstances, the engine will begin to show warning signs long before a catastrophic engine-out event occurs. It's up to the pilot/owner to make sure they are listening. Back 30 years ago, they would put a single EGT and single CHT (both analog and with no data recording) into an airplane engine -- insanely insufficient to catch any troublesome patterns. We now have oil analysis that will find microscopic wear particles that hint towards possible issues. If we find a super tiny shaving of ferrous metal in oil filters we can find out where it came from. We now have boroscopy that allows us to easily inspect the condition of cylinders, pistons and valves in ways we couldn't 30 years ago. We also know more about these engines now than we did 75 years ago. Good pilots will operate their engines to not exceed certain temperature standards to prevent stacking the deck against themselves and their engine. Engines will usually give warning signs before they go kaput, and we just need to listen. Further, the new Advisory Circular 90-66C recommends to exit and enter the pattern AT traffic pattern altitude since otherwise it's too easy to descend and collide with another airplane in the pattern. Did you ever consider that maybe you are replacing engine-out risk with mid-air collision risk by enacting these practices? You certainly can't claim it's non-zero for hanging out right above an airport near the traffic pattern altitude for an extra amount of time! How many near misses have you had in 40 years?

    • @ConvairDart106
      @ConvairDart106 ปีที่แล้ว

      @@MalibuMikeCFII As for near misses, I have had several. Descending down into the pattern is not illegal, and was actually done during my training. My instructor learned to fly in WW2, when engines were not so reliable and he taught me many things you will not find in the manuals. As for mid air in the traffic pattern, have you ever done an overhead entry? From 3,000 agl, you can see the entire pattern and who is in it. I myself, had rather take my chances with my overhead entry, than an engine failure over a congested city at low altitude.I also prefer climbing to 3,000 agl before turning downwind on windy days to ensure I can get back if the engine quits. If you are one of those who take an immediate turn to course, you may very well have given up any chance of return. On my first engine failure, had I been downwind of the airport when it occurred, I would not have made it back as the wind was gusting to 20 that day.

It's easier to see airplanes at your same altitude than it is to see them 1000 feet below your altitude. Also, it seems like you are quite fixated on returning to the airport. There are many successful off-field landings all the time that we don't hear about because they don't become a statistic, as long as they don't stall the airplane before landing. I am suggesting there's a strong chance that your techniques are over-correcting out of fear of landing in a field somewhere. We all should prepare for where to put the airplane down if we have an engine failure at 400' AGL, and nearly every airplane needs to strategize for that, since it's likely too high to land on the remaining portions of most runways but too low to complete a turn back to the airport. The techniques I like to employ are keeping the airplane continuously within glide distance from the airport while flying a pattern wherever possible, and keeping sharp on my power-off 180 precision landings.

If you are using either for approach and the engine quits, you are unlikely to make the threshold. I live in western Washington which is heavily forested, and my father was killed flying into trees spotting salmon in Alaska back in 1967. I refuse to let the FAA force me into flying low over trees, or any other dangerous terrain.

      @@ConvairDart106 I personally don't know of any CFI that recommends you always assume an engine failure is coming and VCOA until at a safe distance to glide somewhere. That seems like a severe overreaction and introduces more mid-air collision risks (mid-airs are almost always fatal) whereas landing on a road or a field is rarely fatal. Like you pointed out, ILS procedures with a 3 degree glideslope assume you have power otherwise you will definitely not make the airport. There are many tradeoffs regarding risks in aviation that we have to learn to live with. Often the least risky thing to do is stay at home and not travel anywhere because you could get into a fatal car accident even at 30 mph. We can't live like that, though! Humans are inherently terrible at estimating risk. Some will happily cross mountains but be very sheepish thinking about crossing Lake Michigan. What about relatively flat places in PA for example that don't have roads anywhere nearby, and the clouds force you to fly at 3,000? Again, if all we did was waited for clear skies, unlimited visibilities, and climbed to 5,000 feet above an airport before going anywhere, that's no way to fly in my opinion.

    Can you show where you came up with 355fpm? The POH shows, even with the 140hp engine, it should have been able to climb at 550fpm. I understand it had the 180hp engine. Either way, none of it matters because the crash has nothing to do with density altitude. Almost guaranteed this is spatial disorientation. The increase in speed before CFIT is pretty telling. I’ve flown singles out of CNY, you’re really really harping on DA but that plane should have had absolutely zero problem out climbing the terrain. It wasn’t high DA.

      Feet per minute is not the same as feet per nautical mile. If you're climbing at 600 feet per minute but flying 180 knots over the ground, that's only 200 feet per nautical mile. Climb gradients are specified in feet per nautical mile because that's directly convertible to the climb angle whereas FPM isn't, since then you also need to know the ground speed. Feet per nautical mile is the climb rate (in feet per minute) multiplied by 60 then divided by the ground speed in knots.

I just don’t see anything in the data given that shows climb performance has any bearing on what happened. It was not high DA.

      Sorry for the confusion. 355 FPM when flying approx 80 knots (IAS) and then adjusted for ground speed at a relatively high density airport is like doing almost 90 knots (TAS) so roughly you're traveling 1.5 miles per minute so divide 355 by 1.5 to get 236 feet per nautical mile. That is just over half of the requirement (456' per NM) to make an IFR departure from runway 21. Definitely severely risky business. However if the airplane had the engine upgrade as many are speculating, it would have made it less severe of a risk but still a moderately risky departure and that's only if everything goes exactly as planned. Unfortunately in these types of accidents there are often multiple links in the casual chain of events that doom a flight; spatial disorientation via somatogravic illusion was the dagger here as you said.

So he was turning into a tailwind. Yet again, his climb performance had zero bearing on this accident. The plane, if configured within POH parameters, was 100% capable of out climbing the terrain. The DP isn’t relevant. Thousands upon thousands of planes depart safely every day from airports where they couldn’t possibly meet the DP requirements.

    Having read the preliminary report myself, I was also wondering about it being a stuck valve scenario. And as you pointed out there is often no physical evidence of the condition after the fact. I also experienced a stuck valve situation with a Millenium-rebuilt Lycoming O-360 while working for an aerial imaging company years ago, but I had the benefit of an altitude surplus for the nearest airport KBUF. It was my first flight in this particular aircraft since the rebuild several months prior. Onsite FBO maintenance didn't find anything wrong, so my boss asked me to fly it back to base. I refused. So another pilot was sent out to fly it back. He got 10 miles from KSYR night IFR when cylinder 4 detached from the block. I have a video of the destruction somewhere.

    I had a similar experience with a freshly overhauled engine in my Comanche where on take off it would occasionally start losing power when I was 2 to 300 feet above the ground. I had about four different engine shops, checked the engine out, and none of them could find anything wrong with the engine. There were times it would do this and they were times it would be normal and take off. I eventually found out that if I adjusted the RPMs back to climb position instead of takeoff position with the engine, running a little slower on the RPMs at full power that the engine would run. Normally it was only at high rpm that the engine occasionally would do this. I then took it back to the original shop that did the overhaul and told them the story. They found that on one of the cylinders there was an exhaust valve spring that would work normally, except occasionally on a high rpm it would not work. At high rpm, there was a weak spring that was cracked, and would not close the valve properly, thus injecting exhaust back into the induction system, which took power away from the other cylinders. They replaced that exhaust valve spring, and after that, I never had a problem. It sounds very likely that this is what killed McSpadden and his friend.

    Good analysis and sad loss is about all I want to say. I'll add that with a four banger, losing a cylinder means a twenty five percent power loss. Given there altitude of 2000 msl or so that became a thirty percent power loss. So, an IO360 that could develop 180hp at sea level is down to 120hp with loss of a cylinder at 2000 msl. 70 percent power means the airplane is flying like it's at 10,000 feet. Now, we have two big guys and I'm assuming full fuel in a turn back to the airport with gear in transit. I've seen the satellite photos for that airport. The options taking off from RWY 32 aren't great with neighborhoods and wooded areas. As well, a pilot with an engine still running is always going to choose an airport. I think any of us could have found ourselves in this situation. Again, this is a sad loss for both of these gentlemen and to the aviation community.

    • @MalibuMikeCFII
      @MalibuMikeCFII ปีที่แล้ว

      Losing one cylinder is absolutely not a 25% power loss. This is not a mathematics equation. In a 4 cylinder it means you have almost no power at all. This is primarily because there is now a gap and asymmetry in the power production of the engine that the other 3 cylinders cannot overcome. You don't have to look far into examples of valve failures in 4 cylinder engines to verify this. In a normally operating 4 cylinder 4 stroke (suck, squeeze, boom, blow) engine, the cylinders take turns making power. When one cylinder takes a vacation, imagine a tug of war rope where nobody's holding the rope for 1/4th of the time. It's not hard to imagine the other team winning no matter how strong the other 3 people are.

I encourage you to watch webinars from Mike Busch (most respected A&P/IA in the world AFAIK) on the Savvy Aviation youtube channel to help form a better foundational base of your theory of engines. There you will uncover a popular quote of Mike's that if you lose a cylinder in a 4-cylinder engine, you'll have to put it down in a field, but if you lose a cylinder in a 6-cylinder engine, you'll just have to change your underwear after making it to the nearest airport.@@scottw5315

I routinely fly a Cherokee 160 out of Carson City NV (4700’ altitude, 6100’ runway) using no flaps for takeoff so I am in best rate of climb configuration at liftoff. WIth a similar altitude and longer runway at Canyonlands, Col Larsen I think would have been better off with a clean wing on that 7000’+ runway. Less to contend with, climb straight ahead until 74 knots, then turn. These old POHs… over 50 years old in this case… have not been refined or improved and do not provide the degree of guidance one is used to in more modern aircraft, or mililtary aircraft that this pilot was used to.

Was there supplemental oxygen on board? AIM recommends supp O2 above 5000’. 2). Night, single piloted, single engine over terrain and very forbidding country. Where do you go with an engine failure? Even, say, a voltage regulator failure? You have 30 minutes at night to get it down before your battery goes. 3) Inadequate climb performance at this DA with this load. No margin of safety. 4) Pilot may have been instrument rated, but did he have instrument currency or recency of experience? 5). The Black Hole scenario for this takeoff is an extreme challenge for an instrument rated, instrument current pilot. 5) The POH numbers from 1966 in this case are demonstrated on a brand new airplane with a test pilot at the controls. What will YOUR 57 year old airplane do? Do you know? Have you test flown it against the POH numbers? 6). As Mike mentioned, the aircraft has probably slipping through the air, requiring right rudder, at the departure end of the runway. Out-of-balanced flight kills climb performance. Again, Martin of Safety. If you don’t have a 25% to 50% margin above the POH performance numbers, reconsider. Yes, if flown at all, this flight should have been a daytime flight with a very fresh pilot. Very sad, my condolences to the family and friends. Margin of safety, people, margin of safety.

    One very important technical piece: the speeds on the ADS-B track are GROUND speeds. Note at around the 14 minute mark when Mike zooms in, the adsbexchange software actually adds “ground” to the speed annotation. This means, since winds were basically calm, that these are TRUE Airspeed numbers on the ground track readout. Indicated Air Speed, which is what drives aircraft performance through the air, is about 8%, or 6 knots LESS, than each of the numbers presented on the ground track. Vy, or best-rate-of-climb speed for this aircraft, is 85 mph per the POH, or 74 knots, with a CLEAN wing. In my opinion, the IAS of the aircraft at the departure end of the runway associated with the 68 kt and 72 kt readouts of the ground track is therefore 62 kts and 66kts, respectively. For this Piper Cherokee, this is compatible with struggling in ground effect with 25 degrees of flap still out. Likely Col Larsen retracted the flaps after the turn. To get best performance for climb, an IAS of 74 kts should have been maintained, or GS/TAS (assuming no wind) of 80 kts.

I reported the incident to my A&P and because it was an intermittent problem he could only suggest replacing the alternator or voltage regulator and see if that cured the problem. I wasn't interested in his shot gun approach so I continued to fly the plane. The last time it happened was on an Angel Flight mission with 1 pax and as luck would have it I was over my home airport about half way through the mission and cycling the alternator switch did not bring it back on. I was VMC at the time so, without declaring an emergency I told ATC I had an alternator problem and diverted to my home airport. After arranging alternate transportation for my pax I walked down to my A&P's shop and he was still in the shot gun mode as far as troubleshooting. Long story short, I did some trouble shooting and found a loose connection at the voltage regulator. Problem solved! With regard to your decision to declare an emergency, who would find fault in that. Declare and use all the resources available to you. Personally, I would not have chosen to fly a low instrument approach back into the departure airport. If I was on top in VMC with plenty of fuel and VMC airports nearby, I would have headed for it.

      I explained this in the video. A stuck valve doesn't necessarily result in a damaged cylinder nor permanent loss of compression. It can un-stick after the engine cools off. There are ways, though, to ascertain the probability of a stuck valve by performing the Lycoming wobble test that the manufacturer outlines.
