      @@GARDENER42 Interesting question. I assume the tanker has volume gauges on the flight deck to check her tanks and with Colson being an American operator the read-out will be in US gallons. If not they might depend on the read-out at the filling station for loading. If the equipment for filling was Australian the read-out may have been in liters as I believe the Australians have gone metric in most cases.Having previously used the imperial gallon, any conversion tables will be from liters to gallons, without indication of the "imperial" adjective - as that was the only gallon they were used to - opening the possibility of the aircraft being heavier than the pilots suspected and being more sluggish than they were expecting.
      On the other hand the ATSB report seems to be very comprehensive, and if either pilot reported a sluggishness in the aircraft the ATSB would without doubt have looked at the load factor, which I suspect will be SOP in any case.

    I'm astonished that any experienced pilot would let N1 decay to 30% in such circumstances. You simply cannot expect decent throttle response from 30%. This has ALWAYS been a classic limitation of jet engine characteristics (Mulhouse/Habsheim with the A320 comes to mind !).

    • @davidatovar
      @davidatovar Год назад +12

      My conclusion, especially since they survived, Is they got over confident with the multiple drop runs and were testing how Low And Slow they could get each time because of their overconfidence in their expertise and the ground jumped up and bit them, the picture of the terrain with the glide path shows they we're putting the pickle in the barrel but you can't win all the time.

      To crash a jet aircraft because you failed to remember engine spool-up lag from idle, is the most amazingly embarrassing way to lose an airframe. I don't like to speak ill of these pilots, but this is something that quite honestly, never should have happened.

      @@iankemp2627 I find it quite bizarre that they should get so low and slow to be honest. A Turkish 737 did the same approaching Schiphol, Amsterdam too and crashed but a defective radio altimeter played a part there in reducing the throttles to idle incorrectly, over-riding the set airspeed (140 kts IIRC) on the MCP.

  • @davewitter6565
    @davewitter6565 Год назад +9

    Part of the pre drop checklist would be to deactivate the GPWS. I am surprised they use flaps 40 and not 20. That would probably add 10 knots. That is a lot of drag, combined with below reference back side of the power curve. The RA and altimeter are for reference for what is a visual looking out the window maneuver. 1800 v/s is unstable should have been a go-around callout. 30% N1 is low considering 60% N1 is normal for a stabilized approach maybe a little less because you don't have the gear out. Glad the crew got out. Kudos on the excellent reporting.

    28:10 - The last fly around the crash site, seeing the hollow edges of the terrain, is from a 3D camera, similar to what dentists now use to collect the tooth dimensions and profile for a crown. In the dental case, the image produced is just used to give the tech confirmation that the data set is complete. In the crash case, direct measurements can be taken from the data. I have several color pictures of my teeth and gums done that way. The crowns fit perfectly.

  • @shenandoahhills7263
    @shenandoahhills7263 Год назад +10

    With airliners we were required to be on speed, engines spooled, configured, and on glide slope at a 500 foot window above the touch down zone. Failure to meet the requirements was a mandatory go-around. This came about due to the early B727 crashes where they would be high and fast on approach and attempting to get back to the glide slope from above with the engines at idle. Was there a window for this type of operation??
    Secondly the radar altimeter would have been bouncing around due to the irregular terrain, thus it would only serve as a rough back up, alerting the crew that they were closing on terrain. The airspeed indicators and the radar altimeters both had bugs which would be set prior to the approach.
    Flaps 40 is maximum flap extension and is a very high drag configuration. My airline discouraged using that setting if it was not required for fuel saving and to reduce wear and tear on the flap mechanisms.
    Question? What where the changes to the FOM and recommendations to prevent further such accidents?

    Flying low and slow over unfamiliar terrain is about as risky as it gets. It’s any wonder we don’t lose more air tankers. Which speaks volumes about the crews and procedures. The most important thing to remember, expensive as it is, the aircraft can be replaced… the crew, not so much. I’ve worked with the 737 Air Tankers off and on since the first one got carded. Had some interesting times working those birds. As usual excellent analysis and explanations!

      Heard another comment here pointing out that since the 737 wasn't designed for low and slow, but for high and fast, it's adding a particular risk to these kinds of operations. Do you have any thoughts on that? I'm just a layperson but it does raise an interesting point. I don't know if there's any other airliners or other similarly sized planes which are better for low and slow operations and would have better performance in situations like this.

    • @christopherestrada8576
      @christopherestrada8576 Год назад +3

      @@R2Bl3nd it’s not a matter of “design”, they are all designed to change their configuration (flaps and slats) for low and slow because it’s how they land! Hahaha! Flying low and slow is risky for ANY aircraft because altitude and airspeed generally equate to safety, mostly because it gives you more time to address any situations that might develop. I am by no means “expert”, but I’ve been around aviation my entire life and been in the wildland aviation arena for going on 8 years now.
      The Canadair CL line of “Scoopers” are the only built for purpose firefighting aircraft in the world, as far as I know. The Russians may have a version as well but I’m not certain. ALL other air tankers were built for other purposes, a mix of former airliners and military aircraft. This is absolutely NOT an issue because in just about every case they are operating well within their design envelopes, 737 being NO exception. Obviously they’ve been modified but each aircraft must pass a very strict inspection/test phase and must qualify (card as we say it) before they are allowed to be contracted. Similarly the crews go through extensive special training over multiple seasons before they are fully qualified. Most tanker pilots are highly “experienced” airmen who have had other careers before becoming aerial firefighters. The maintenance cycle is higher on certain critical parts of air tankers as well because of their high “cycle” (take off and landing frequency) rate, and because of additional requirements on the equipment, if that makes sense. For example engine igniters are changed on a much more rigorous schedule because they are turned on during every drop as a safety measure against possible engine flameout. Normal aircraft operating procedures don’t require such things. And I can tell you the crew chiefs and mechanics swarm over their aircraft the moment they stop upon returning to an airtanker base. EVERYONE on the flight line of a tanker base is CONSTANTLY looking over the aircraft for ANYTHING that might be amiss. If it looks stupid, chances are it IS stupid and should probably be reported immediately.
      Again these are just my experiences and observations, the crews than maintain and fly the birds know the deeper truths. And sometimes we won’t ever know the truth simply because of how the world works.
      Just as the wildland ground crews have learned very hard and costly lessons throughout the history of wildland firefighting so has the airtanker community. This time will be no different, lessons will be gleaned from the ashes and the community will be safer and stronger for it. Thankfully this time the price wasn’t paid in blood. It’s always a terrible thing when a tanker goes down. I know EVERY single time one leaves a base I’m on I say a little prayer for their safe return… because we just never know. It’s all part of the job. I hope that cleared some things up!

    This "nearly but not quite flat" terrain crash shares so much in common with the last Coulson crash in Australia, it's just spooky.
    Not quite flat is much harder to fly in than actually flat or really steep. There's almost no visual clues in rolling terrain.
    Out landing a hang glider you want to land up hill, even if there's not much slope. Over cultivated land there's features that can help, but over scrubby land there is almost nothing.

    The time scale on the graph shows about midday to 1:30 ish, if that is correct? In our harsh sunburnt country, at or around midday, the shadows that give form to the landscape, disappear. So, they may not have been able to define the knoll by eyeball. i assume it would take extra training to fly vfr when there are no shadows.

    I can see that because you know how to fly a 737 commercially doesn't make you a good pilot at extreme low level flying...what you take for granted in commercial flight can not be overlooked flying that close to the ground. I'm learning from Juan that eyeball training at 150 AGL over a flat runway is only the beginning of eyeball training over "seemingly flat" terrain. In this case wouldn't the lead dog's input be even more important to pass along information to the tanker crew about the type of terrain where there are ridges that can not be seen from directly over head. I have learned today that flying over a California mountainous area is not the same as the even more hazardous extreme low level flying in Australia...especially with a big "cumbersome" 737 jet that doesn't have the quick reaction time capability of a smaller prop driven airplane. I am glad the pilots of the 737 made it out safely and are still alive to pass that experience along for better flight safety in future fire fighting. Thank You Juan.

    Thanks for this. I live in Western Australia and have been to the Fitzgerald River National Park many times. I was astounded (a) that this happened, and (b) that the crew survived. I have read some opinions that suggest that a Boeing 737 is quite unsuitable as an air tanker, because low-and-slow flying is required for firefighting, and 737s are simply not designed for that - they are designed to move a load (usually people) over long distances at high altitudes and high speed. So this sort of flying goes against many of the basic design criteria of a 737. A specific problem (apparently) is that a swept wing is not good at rapid reversals of descent/ascent. I'm no aerodynamics expert - I'd be interested in your take on that.

      I am a retired National Park Ranger who worked in that Park briefly in 1986, but have a good memory of the terrain, soil and vegetation. Prior to that career I worked for 9 years in the precursor to the ATSB, so I have aviation knowledge and experience. As a ranger I developed a lot of fire experience and my take on this issue is that the B737 is a good tanker for Australian conditions; consider the distance from their base in Busselton to this fire site. The ex-airliner is ideal in having a very good transit speed from its base when repeat drops are necessary. Does the USA have a 737 capable runway every 100 miles? Perhaps you do in limited areas but that sort of luxury is pretty rare in a global context. The ATSB and Juan have correctly identified the cause of this accident; thank good luck that the crew walked away!

    I observed a 737's approach for a landing at my local airport and thought it looked odd. It looked like it wasn't moving at all, and just floating. Later I found the details online and it was dipping to 115 knots into a 5 knot wind. After that, they recovered to 120+ knots. It looked magical watching it and since I am no pilot, I don't know how close they were to a stall.

      Some smaller aircraft can actually fly backwards relative to the ground under full control, given a healthy enough airspeed from headwinds etc.

    I wonder if a physical stop on the throttle would help here. So if they transition to low level flight their checklist calls for a physical stop gets flipped to the throttle leavers, so they cannot be moved to a too low setting.
    If the aircraft is too fast, the crew would then need to result to speed brakes instead to slow the aircraft.

    Very good and precise walktrough of what happened. Visual operations are easy but also the easiest way to get into trouble if you are not on top of the situation. Instrument approaches have very well defined segments and limitations that you work your way through until you land or perform a missed approach. Not so much on a visual approach which makes it difficult for the PM to call a Go around. Something to think about in the way you brief the approach for all of you that do a lot of visual operations.

    • @gen4ls7
      @gen4ls7 Год назад

      I would have thought that as soon as the captain realised he was close to stalling he would have retracted the flaps to remove as much drag as possible at the same time increasing thrust.

    • @markcoveryourassets
      @markcoveryourassets Год назад

      ​Hi, ​@Ron Myers , I think that raising the flaps even a bit will reduce the lift of the wings and lead to a stall unless airspeed is increased. I suppose that landing speeds have a flap setting included, like the drag of the landing gear is factored in. The first time I learned about that was when a new private pilot had to make multiple approaches at a local airport. Each time she had to go around she would have to raise the flaps as she went back into the pattern. The flight data showed her doing this at consecutively lower airspeeds. This led to her stalling on the way up from her last attempt. I only fly Sims, but it was a major lesson to me.
      All three on board died. They were flying to visit her dad, who was in the hospital in my city. What I did not understand was why she planned her flight to land at our 2nd busiest commercial airport instead of one of the many smaller GA airports. The situation started off with her being asked to abandon her first approach because the faster landing airliners were backing up behind her. Then she was directed to a secondary runway. She was in over her head, with nobody else on board who knew how to fly who could have helped with checklists or watching airspeed. And she got handed off to another controller at the shift change which was in the middle of all of this. People talk about the sea being a cruel mistress. The sky is unforgiving.

      The barometric altimeter would be set to give height above sea level and the radio altimeter height above ground.
