This is the state of our pisspoor public sector companies. Bad enuff that the Indian Airforce has experienced a 40% attrition in our Mig-21's without exporting that $hit to other countries.
The Ecuadorean Air Force chief reiterated that the contract stipulates a return clause if provisions were not adhered to, which if the alter engines are the cause, warrants a remit.
But, I want you all to distinguish between the violation of terms and
cause of the crash itself: the latest assessments have it that the copter may have come under rotorwash from an adjacent craft flying in formation, banked left sharply and attained a cyclic limit in trying to correct to the right. In technical terms, when cyclic
saturation occurs- particularly at low altitudes- it is often difficult to correct, stabilize or acquire lift.
This video for example, gives a simulated demonstration of that dynamic. Low anti-torque tail rotor authority and a crosswind conspire to create a similar effect:
