Z-10 thread

[Black Shark]

According to Chinese news sites, witness reports a loud boom from the tail before it crashed. The wreckage does show that the tail has broken off.

A i have my doubts with this witness reports, a pilot can maybe distiguish where the "boom" sound came from but from several hundred meters you need at least a visual effect to be so precise where this "explosion" happened.

Usually investigations of crashed aircrafts takes several months and often aren't published for common folks anyway.

Time will tell, but i doubt that this will be detailed published, maybe just a vague explanation what militaries usually do.


Edit: On this site there is a very short video of the crashed WZ-10

Wrt the reliability of witnesses I remember hearing this anecdote perhaps twenty years ago: The leader of a course in aircraft accident investigation on an airfield in England arranged with a pilot friend that at the time the leader and his eight students walked to their midday meal he would fly in as if to land, do something odd and fly away again. When asked to write down what they had seen none of the descriptions matched and none agreed with what the pilot reported he had done, not even the description from the leader who had been prepared to see something odd.

The pilots are okay.

经@陕西消防 证实：今日下午2点左右，一直升飞机在渭南固市镇农田坠落。据目击者称，飞机在行驶过程中，尾翼突然发出一声巨响，随即直升飞机失控，坠落农田。目前公安及消防干警已赶至现场，受伤机组人员已被送往医院。事故原因还在调查中，一切以官方信息为准。

It says the helo was flying while an explosion was heard at the tail rotor, and the helo lost control. The two pilots were injured and sent to hospital. So, they survive the crash.

Very good to know that both pilot and WSO suffered only minor injuries and are now recuperating. Landing gears and crash seats worked as intended.

Seems indeed to be a flight into power lines, if you look closely at the strongly bent rear cablecutter (as well the front one is even missing completely).

The only thing that i have a problem is this report of the "witnesses" that they heared a "boom" from the tailrotor, i mean if you could locate where this suppossed explosion comes from as an landfarmer who has no idea of military equipment, means you should be able to see that this helicopter had to fly through power lines and get damaged and usually it is very easy to comprehend what must happen to helicopter when you see power lines bursting and sparks coming from it, so lets wait for the pictures of the cut power lines to see if this is true.

To admit I would count an eyewitness report from a farmer - no wanting to discredit him, but like You said with maybe NO understanding in military technology - in describing an accident like this a reliable source especially when all evidence come to a different - much more likely - conclusion.

As such I think he heard a "BANG" and saw maybe even the tail falling off ... bingo in his conclusion, there was an exposion in the tail.

Looks like maybe the power line ran up against the rotor causing the helicopter to go vertical and then crash on its tail first.

I think what you said is correct. To be honest, for people that have no military knowledge, if they have seen a car or a plane, they can still tell where the head or tail of a vehicle. The helicopter landed very closely to the powerline towers, so like others have said, it may have flown through the powerline. The witness may see that something weird happen to the tail and the sound corresponded to that abnormality. The witness may say that there is a "boom" sound and the media would probably just translate it saying explosion at the tail.

My in-laws just came to the States to visit us last week. They have been showing us photos they took while they were in China. One of the photos happens to have 5 Z-9's flying overhead. My mother-in-law insisted they were 4 "small ones" and one "huge one", while it was clear as day to me that they were all Z-9's. But she kept saying it was a "mother duck" leading 4 "baby ducklings". So yeah, for someone not familiar with military equipments, it would be difficult to tell what is what.
