In Ukraine, presented a version of the test pilot about the reasons for the fall of the An-26

The Ukrainian edition published the conclusion of an expert who studied the circumstances of the fall of the An-26 aircraft with cadets of the Kharkov National University of the Air Force.

The study of test pilot Alexander Pakholchenko differs significantly from the results that the Ukrainian military has arrived at so far. Let us remind you that they asserted that the aircraft engine was in good working order and the quality of crew training was high. However, the opinion of the test pilot casts doubt on the words of high-ranking officials of the Armed Forces of Ukraine.

According to Pakholchenko, the An-26 on that ill-fated day conducted "conveyor trainings" - that is, it did not sit down to the end, but after landing, immediately took off again. Such training is usually done to increase the intensity of the exercise and to conserve expensive fuel.

When the plane took off again, the left engine performance deteriorated sharply. The oil pressure of the gauges turned out to be at the level of 60 kg / cm, while the norm was 91-94 kg / cm. Since everything was happening very quickly, the on-board equipment was not able to quickly clarify the deterioration of the indicator and inform the pilots about it. The pilots could not stop the plane from taking off, since the point of no return had already been passed according to the instructions.

According to Alexander Pakholchenko, during the acceleration of the aircraft, the pilots might not have noticed the difference in thrust of the engines. As a result, the crew commander did not make a decision to cancel the flight, and this was the fatal mistake that led to the An-26 crash.

The onboard technician discovered problems with the left engine when the plane had already taken off the ground. At an altitude of 150 meters, the pilots began to remove the load from the left engine. After another three minutes, they began to reduce the load on the right engine. But for some reason, the crew did not equalize the oil pressure on both engines. The speed began to decrease. When it dropped to 170 km / h, what experts call the left propeller feathered - the blades were rearranged so as not to create air resistance and to avoid arbitrary rotation of the propeller.

Then the plane began to roll to the left wing half-wing by 50-70 degrees, and only after that did the crew commander try to stop sliding by pressing on the right pedal. That is, according to experts, the commander of the An-26 demonstrated his inability to act in such a situation and balance the aircraft with asymmetrical thrust.

Among the key reasons for the crash of the plane, expert Pakholchenko singles out three: insufficient training of the crew commander, limited engine power, low flight altitude. It is these factors that played a fatal role in the fate of the An-26 crew and the cadets of the Air Force University on board. In addition, the flight control group was also unable to provide the crew with qualified assistance in an emergency. The fact that the last engine overhaul was carried out 30 years ago is no longer considered.

For obvious reasons, this version of the causes of the disaster is not at all beneficial to the command of the Ukrainian Air Force. After all, it reveals the problems of the Ukrainian military aviationthat are systemic. First of all, it is the quality of the military equipment used and the level of personnel training, which remains very low.

However, while systemic problems the Ukrainian command will not solve, but hide, it will not be possible to avoid such situations in the future.

Comments

[the finish]

Turkish defense giant Baykar Makina, whose technical director is the son-in-law of the current president of Turkey, is negotiating with the Ukrainian company Ukrspetsexport on the localization of production of Bayraktar TB2 attack drones in the country.
The Ministry of Defense of Ukraine also plans to purchase from 6 to 12 unmanned systems, which include a corresponding number of control stations and 3-4 directly UAVs for each of them.
Thus, with 48 UAVs planned for acquisition, Ukraine can become one of the largest foreign recipients of Turkish attack drones, and taking into account the SKD in the country, the cost of each complex will decrease by 35%.
At the same time, interestingly, the Ukrainian side does not exclude changes to the design and "stuffing" of the UAV and further export of "modernized" vehicles.
According to the general director of Ukrspetsexport, there is already "an agreement with the Turkish side that we do not go to those countries where they are already present with these products - to Azerbaijan."

It is time for Donbas to study the tactics of Azerbaijan ... and think about how to respond ..

Do you believe it? Not that some kind of negotiations are underway, but that Ukraine will produce something. I have very big doubts about this. Moreover, with a production program of 6-12 pcs.

[Vladimir]

The article seems to be about something completely different, where does the Turkish drones have to do with it?

And what does this have to do with the fall of the AN-26?

[Thrall]

This version of the causes of the disaster is not at all beneficial to the command of the Air Force of Ukraine

Even less profitable is the version with the son of the Commander-in-Chief of the Ukrainian Air Force, who was on the second transport aircraft, which was allowed to land before the AN, which had problems.

[orionvitt]

Quote: Thrall

let the AN who had problems land earlier

One might think that from such a turn of events, the problems on the second AN disappeared. The whole question is not who went to land earlier and who later. The issue is the systemic collapse of aviation in Ukraine (as well as the entire country as a whole), which Ukrainian politicians will never recognize.

[Lipchanin]

The fact that the last engine overhaul was carried out 30 years ago,

And there is where and what to repair.

First of all, it is the quality of the military equipment used and the level of personnel training, which remains very low.

That's where the dog rummaged

[fruc]

To whom we are interested, these are the problems of Ukraine. The plane crashed, people died, let their prosecutor's office deal with it. Why stir up this event with us.

[Lipchanin]

Well, if in the morning the teachers' problems were discussed, then this one can also

[Bort radist]

Debriefing, reduces the number of flight accidents.

[Vladimir Mashkov]

Qualified assessment. Yes, power loss on takeoff is almost always a disaster.

[Clear]

For obvious reasons, this version of the causes of the disaster is not at all beneficial to the command of the Ukrainian Air Force.

Unfortunately, any conclusions on high-profile events are first considered from the point of view of political expediency. And don't give a damn about people.

[fruc]

These are the comments of the official freaks on the plane crash with the chorus. Alexandrova 25.12.2016/XNUMX/XNUMX
One of the most scandalous was the opinion of Yuri Biryukov, Poroshenko's adviser.
He apparently decided to "witty" link the death of a Russian military plane and another tragedy - the fatal poisoning of dozens of people in Irkutsk. On his Facebook page, the official wrote: “The plane of the Russian Ministry of Defense crashed ... There was only one desire - to take a bottle of Hawthorn to the horde's embassy.
There are no words, as they say.

[KCA]

All this is very strange, the AN-26 landed on the 1st engine more than once without any special problems, and at low altitude and low speed it is not a question to land at all

Nothing strange

[loki565]

It all depends on the skills of the crew, we also had cases of stalls during landing.

[Bort radist]

AN-26 is one of the safest aircraft. If I put the screws of a failed engine in a weather vane, then they should have quietly sat on one. If the propellers are not placed in the weather vane (the propeller does not rotate, the blades are flat towards the stream), autorotation begins and the plane turns over. In flight training with autorotation, roll more than 70 degrees ...

[iouris]

Yes, at least two. There is a version: my word is against yours.
Only the act issued by the commission of inquiry should be discussed. Well, the commission will work it out, find out that the catastrophe was inevitable, but due to the lack of funding, it was decided to fly, an "aggressive hybrid war" takes place ... And the war will write off everything. And on what political platform is this test pilot?

[loki565]

There are already versions that the priority of landing was given to the son of one official instead of the emergency board.

[iouris]

This is bullshit. But if it works and manages to divert the attention of the "public" from the real grave problems, then this is not nonsense.

[kit88]

But this is not the opinion of a sofa expert. This is an analysis for the investigation of the Antonov test pilot.
Turns out that.
An instructor pilot cannot fly.
The flight control team is unable to provide assistance to the crew in an emergency.
The catastrophic situation began to take shape due to equipment failure, therefore there are many questions for ITS.
It is better to keep quiet about the endless extension of resources (and it is not known how they were still extended).

This is how things stand in aviation ...
A decent Commander-in-Chief of the Air Force, after such conclusions, is simply obliged to get his Makarov out of the safe with one cartridge.

The institution of reputation has been destroyed. I doubt that this is precisely the "opinion", and not what should have been said at the right time. Moreover, an investigation is underway.

[kit88]

I doubt that this is exactly the "opinion", and not what should have been said

It is not entirely clear what you mean.
As THEIR resources write:
At our disposal was the conclusion of an expert who was brought in to investigate the An-26 disaster near Kharkov.
The plane crash was analyzed for the investigation by Antonov test pilot Alexander Pakholchenko. His data refutes much of what the military is officially claiming.
As for the personality of Alexander Pakholchenko himself, it is difficult to catch him, for example, in sympathy for the Russian Federation.
Fragment of the story of a participant in the events of 2014, place of action - Crimea:

- Without waiting for orders from Kiev, my friend Alexander Pakholchenko and I decided to overtake the planes of the State Research Center (then the Center was based in the Crimea, and after the annexation was transferred to Chernigov). We were going to fly at night. At first, our commander did not give us permission. In the end, we said we would fly without your permission. You will remain in Crimea anyway. This means that we can not follow your orders. When he realized that we could not be stopped, he asked us to apply for training flights around the airfield, and then fly wherever you want. We applied and took off. We walked over the Sea of ​​Azov, at an altitude of 5-10 meters, constantly maneuvering, because Pakholchenko discovered attempts to take us for escort with air defense radar ...

[iouris]

Until the completion of the investigation and approval of the act, the members of the commission do not make statements. And the relation to Bandera and the Russian Federation does not matter here.

[veritas]

After all, it reveals the systemic problems of the Ukrainian military aviation.

For some reason, it is customary to hide the systemic problems in the post-Soviet space. Maybe this is the common problem?

[Berkut154]

Why was it impossible to immediately, without waiting for the autoflug, fly the left one, start the RUshka, and take control of the situation and prevent the speed from decreasing to critical values? Request a scheme with a convenient turn for entry.

[Bort radist]

There are few flyers here, they saw a weather vane on the roof, I generally keep quiet about autorotation.

[Misha_an26]

Left in denial, RUshka is not needed. And the fact that the screw on autorotation was one hundred percent. Otherwise they would not have crashed. Well, the USP touches the Ukrainians, 27 digs on one side is something. I remember Balashovskaya bursa 3 course. There were times.

Ukraine.

If they managed to register, then they seem to be not completely illiterate.

[ZEMCH]

First of all, it is the quality of the military equipment used and the level of personnel training, which remains very low.

Does Ukraine have other options? The country is not in a position to repair and build new aircraft on its own, or to prepare basic training for them. There people are busy with others, finishing off the remnants.
In a conversation one of the specialists from Ukraine reasoned sensibly: "In order to start the way up, you have to push off from the bottom!" I retorted: "The main rule is when you are at the bottom, stop digging !!"

[Filxnumx]

But for some reason, the crew did not equalize the oil pressure on both engines.

And there is only one reason: any lack of such an opportunity on the An-26 in flight.

The speed began to decrease. When it fell to 170 km / h, what experts call the left propeller feathered

The author, you at least spied the theory, or something. Feathering of the AV-72T propeller (as well as others) occurs not due to a drop in flight speed, but due to a drop in engine speed below the value of the corresponding setting of the autofluor sensor (depending on the engine operating mode, it is different).
