Hard landing video, finally https://twitter.com/KFM936/status/1125124009597788160
It show a "landing", a big bounce, a second "landing" maybe a small bounce, engine fire on the ground impact, and then a lot of smoek. It appears that the right engine kept running? Maybe the right slide deflated slightly? |

Being in aviation claims I’ve seen my share of lightening strikes on all types of jets(albeit no Russian iron), to the point where they are the most benign claims I see. Not one of those aircraft crashed or so much declared an emergency. It makes me wonder about the design of the Superjet.

cabin baggage lock
What do you think of airliners introducing an automatic cabin baggage lock in emergency situations? That would stop people from trying to grab luggage in the cabin in emergency situations.

So many factors, and so much speculation...but hey, that is what this forum is all about, although let us keep it professional. |

By way, thanks for telling the entire non-flying terrorist community what '7500' means. Any other security codes you wish to share globally? 1. No fire on board reported by crew (COMs seem to have been intermittent, not dead). 2. Timing and character of fire is consistent with a likely scenario of a landing with that much fuel. 3. PAX video made during/shortly after landing suggests no smoke in cockpit prior to conflagration on the outside. As to the codes - they are, and have been for a long time, so readily and widely available that no one would bother with looking for them on a message board. |
Boeing and Airbus main wheels are designed to detach and not penetrate fuel tanks, if overloaded or stressed beyond limits. Do Sukhoi have similar design?? |
Someone should have spotted that burning aircraft on approach and raised some alarms you would have thought. |
It bounced/skipped, then came down hard the second time |

In answer to my earlier question, this 360 walk thought reveals flight crew door opens outwards into main cabin.
Debate on if overwing exits should have been deployed is moot as there are no over wing exits on the model photographed. https://www.superjetinternational.co...rjet100/cabin/ It does look like an engine was running during the evacuation. mjb |
I agree with the other poster. Baggage compartments should be locked during take off, landing and during emergencies. We will never know how many lives this would have saved in various accidents including this one.

By any measure that landing(s) was a shocker. If both engines were performing adequately well, then there is no excuse for such a landing - lightning strike - or not. It appears that the landing contributed to the start of the fire.
|
I am amazed at that guy who took the video of the crash sequence inside the aircraft. Did he know how much danger he was in? Even after that last, gear collapsing touch down which must have been bone shattering and then with all the flames and noise that followed? Yet his video was amazingly calm and steady like he was in a movie or a computer game where no one really gets hurt perhaps? A sort of virtual/real reality. Maybe he just wanted some more You Tube likes? Mind bending.

Perhaps flight control issues? It’s easy to say that when you haven’t had to confront the situation yourself... A couple of videos and some few sketchy facts are not quite enough to claim that the flight crew performed poorly. Yeah, the landing looks awful, but I have no idea what challenges they were wrestling with. One could just as easily view the video of Al Haynes' landing in Sioux City with no additional information and conclude that he really screwed that one up, when in fact, he did a pretty damn good job considering the hand he was dealt. |
Yeah, it's a big secret:

I agree right engine runs for about a minute after the aircraft comes to a stop, fanning the flames. Apparently did not deter pax from evacuating (good thing). I have no idea if that was simply how long it took the crew to "unstartle" and run the shut-down list, or if the previous impact and/or hypothetical lightning strike had damaged engine controls (remember "stuck" #1 engine on the Singapore/Qantas A380?) It may simply have stopped only once the fuel had leaked out and burned on the ground.
Salute to whoever it was that ran back into the burning plane. I suspect it was the FO getting the CAPT out of the cockpit and down the slide head-first (dark "objects" on slide). Zero further comment on crew until we know a lot more about what degraded controls they may have been fighting. Agree the fire response was slowish - but we don't know what they were told to expect and how they were deployed. Remember there were comm problems with the aircraft. Whatever else goes on with the SSJ-100, it looks like it may have a "Ford Pinto problem." Tendency to collapse gear in a way that ruptures fuel tanks. |

"doors and bins locked for landing" This would take a few decades to become ubiquitous across a carrier's fleet. A passenger fumbling with the overhead locker is less of an obstruction than one tripping down the isle with a wheelie. Mjb |
While nothing can be ruled out at this stage I would say that if handling difficulties were the cause of the terrible landing attempt then they must have occurred very late in the approach. A pilot experiencing handling problems doesn't simply squawk 7600 indicating a radio failure.

Bounced landings
My first solo I bounced and not knowing what to do nearly destroyed the aircraft. Similarly I had the oxygen masks out on my only one on a jet before I figured out how to handle one.
Many many pilots and a lot of instructors do not know how to salvage one. My last passenger flight in a light aircraft saw the nose gear wrecked when the owner with more than 1000 hours on type bounced and then pushed the stick forward. We were landing upwards on a mountain strip. I stopped his second and third attempts to kill us. I've taught many qualified glider pilots who should have already been shown what to do but didn't know how to salvage a bounce without the luxury of a power plant. Blame the system, lack of understanding and fear. You generally bounce because you have too much energy and if a go around is not possible or desirable then roughly maintain attitude unless extreme. As the energy bleeds off the aircraft will descend and a check back on the stick will produce something comfortable. Part of the problem is the philosophy that the aircraft must be on the ground in the TDZ regardless of runway length available. |

If every landing was in direct law then pilots wouldn't find it "a handful" when they were faced with a direct law landing, no doubt with other problems as well. |

Approach looked fast (flapless?) SSJ version of Direct Law? Stuck THS? Massive / multiple electrical failure can lead to any number of issues. A4 |
TDZ
Occasionally there are conditions that catch even the best out such as wind shear, the effects of low level inversions, stress including fatigue, wake turbulence with a tailwind and a go around or thump it in in the TDZ isn't the optimal solution.

Bounce into an undamped fugoid - something we were all warned about prior to first solo. Bounce? Hold the landing attitude and wait for the impending contact! Or GO AROUND or don’t bounce in the first place. |
