It's what even the Ecuadorian air chief said on the day of the crash. And as reported consistently here on LiveFist, it was indeed cyclic saturation caused by a hard left by the pilots that caused the Dhruv to rapidly lose altitude, tip over and go down. Sources say that the conclusion was drawn as much from the analysis in the US of the FDR/CVR as from the direct testimony of the pilots of the crashed chopper and the one flying directly behind them. More details soon. For now, the HAL folks in Quito can breathe just that little bit easier. But only just.
