It's their ops tempo. Most of the aircraft involved haven't had major upgrades recently. The first half of 2015 interceptions of Russian aircraft
were up 50% over all of 2013. Most of the accidents are engine related it appears.
The Russian military has always been known for maintenance issues, but when they were at their normal ops tempo it wasn't as big an issue. Now that
they've ramped up operations as much as they have, it is.

Can we assume that the auto-gyro feature on that craft is a tad inefficient? Or did it go into auto-gyro at all? I can't tell from the blade
direction ofrotations and there was an interruption in the video.
I see the tail rotor slow spinning. That matchers the claim of failed hydraulics, the statement by the co pilot said the hydraulics alarm sounded
before loss of control, and we see the auto rotation descent…
You can clearly see the rear rotor has failed.. Is it a coincidence that it happened right after they all release chaff? Could that have been the
cause as apposed to some type of internal failure? Just wondering...
Remarkable hte copilot walked out by himself from the burning wreckage. Imagine being in that 1000+ feet above ground and it starts spinning. And
keeps doing it until it hits. That s*** isn't fake.
Amazing to me someone survives that. It's not just the vertical hit but the rotational momentum. They must wear "seat belts" for it? Given they're in
an aircraft and crashing is going to be messy, seat belts are kind of meh, but I imagine they're useful when doing rapid maneuver and of course in
this particular situation when the forces are survivable...
Just my thoughts. Glad someone survived. Not glad he got to see the pilot die and has to go through this though. But I know anybody trained for that
knows this can happen. They must have some preparation.

I don't think it was in auto rotation. The tail rotor failing for whatever reason would cause the aircraft to start spinning in the opposite direction
of rotor torque and consequently cause the craft to lose lift due to loss of main rotor speed in relation to the fuselage. Meaning the power that was
being used to spin rotor is now being absorbed by the opposite spin of the copter itself. I don't know what the tail rotor normally looks like but it
looked like the two blades were not at right angles to each other possibly indicating some type of failure in the tail rotor shaft. Just my opinion.
In reading a little about this particular aircraft i did learn that it has an X style rear rotor that has the blades at a 55 deg angle in relation to
each other as opposed to the traditional 90 deg relationship. But from what I have read the tail rotor is driven via a driveshaft directly off the
main transmission....so I'm not sure how the hydraulic failure affected the tail rotor speed ? But it certainly would have caused loss of control
functions. Anyway it was saddening to see the co-pilot watching the craft burn knowing his comrade was in it. Life certainly has it's hellish
It depends on the point of failure, even with redundancy. I've had jets come back leaking and barely notice it, or come back with one entire system
drained and on emergency backups. Even had one come back with an engine on fire because the hydraulic pump let go and leaked onto the outside of the

Auto rotation you mean? You need some altitude for that, and if the hydraulics were out it would be difficult to control the blades from what I
While true in my humble opinion and experience with several thousand hours helicopter time as a pilot.. The bird suffered a tail rotor failure.
Due to his lack of forward airspeed it really complicated getting the bird and crew down in one piece. If he would have had enough forward airspeed
the aircraft would not have spun like it did and he could have reduced collective (power to the main rotor system) which would have reduced the torque
of the rotor system to the airframe and entered a more crash worthy auto rotation.
Tail rotor failure with forward speed or at a hover (not in the dead man's zone) can be managed in many helicopters. I had one on a UH-1h model and we
landed with no further damage to the bird.. But during my time we practiced simulated tail rotor failures in different environments.
On the other hand there are helicopters that almost become totally uncontrollable even in cruise flight during a complete tail rotor failure... A
TH-13 had a violent pitch up with complete loss of tail rotor during a training flight around 1971/72? at Ft. Rucker, Alabama. The instructor and the
student survived but I do not remember the damage to the bird.. I was amazed at how the bird reacted and how the instructor managed to get the bird
down and they survive. To get the nose down on that bird (if I remember right) the instructor said he had about 1/2 inch of full forward cyclic
control once he finally got control of the acrobatic wanting TH-13..
Our Russian helicopter was in the dead mans zone for auto rotation because of lack of forward speed.
Another helicopter that lost tail rotor without forward airspeed/
i think the russian pilots flying these guys are almost like our blue angles but for helicopters so they are the best of the best and mostlikely why
the craft did not land in amongst the spectators RIP to the pilot and speedy recovery to his co pilot
