I repeat for the people the information:

TUSAS has a serious problem with horizontal stabilizers on KAAN.

Two foreign companies were hired for assistance. In fact, both approached the problem and completed a report stating that the problem with these stabilizers, as they are, is technically unsolvable.


In my view, this is precisely where the first suspicions arose—literally from the very first minute of the Kaan’s maiden flight. No one on the forum dwelled on it, as it was far from the most significant aspect.
It seems the concerns regarding the Kaan’s horizontal stabilizers stemmed from the fact that, early in the flight, they began to oscillate with a rather large amplitude. Given that this was the fighter’s first flight, such minor issues are entirely typical.
What actually happened? To put it simply—without diving into complex technical analysis—the Kaan’s onboard computers essentially "erred on the side of caution," building in a much larger safety margin than was strictly necessary. That’s all there was to it!
By the second flight, everything had been corrected, and no further noticeable oscillations occurred. In fact, this is precisely why numerous test flights are conducted—often over the course of several years—to identify and iron out such nuances.
This is a perfectly normal occurrence—so normal, in fact, that it cannot even be classified as a "problem."

I invested my life savings, sacrificed much and went through considerable difficultly to start a new life in Turkey because i believe in that in the end the Turkish people will succeed. And Kaan is not an exception to that belief. We are with the engineers at Tusas and Baykar and even the companies that are not public, in our hearts and in our prayers and we believe in you and appreciate your sacrifices and struggles. And we will be patient and continue to rejoice at your successes of the past and in the future.

Since our forum began its operations in 2020, there is no information here regarding the crash of the first production-model Su-57, which occurred in December 2019.
It is worth noting that the crash was linked to a malfunction in the horizontal tail assembly. (Photographs of the wreckage remain classified)

Here are link to information about this incident:


A Russian source here identifies the cause of the accident:

"According to unofficial information, the accident was caused by a failure in the aircraft's integrated control system at an altitude of approximately 10 km; this resulted in the stabilizers shifting to the opposite position, causing the aircraft to enter an uncontrollable spin and eventually crash 111 km north of the KnAAZ Dzemgi factory airfield"


The most interesting part is that this wasn’t actually the first accident involving a Su-57. The first crash occurred back in 2014—right in front of an Indian delegation that was there to observe the flight!
In 2018, India announced its withdrawal from the Su-57 project.
