I came across this article from India where the manufacturer of the helicopter (Hindustan Aeronautics Limited) kept lying about the safety issues with its helicopter. It resulted in a series of crashes over the years in India and Ecuador.

Question 1: How big is the problem of cyclic saturation with a rigid rotor system? Can a rotor actually break mid-air because of it?
Question 2: Is there a Standard Operating Procedure when one enters into a situation of cyclic saturation? The correct response according to some is to lower the collective and then turning cyclic to the right. But that sounds a bit vague.
Question 3: There is mention of a warning system that would provide visual and audio warnings. How long would it take to retrofit one into said chopper?
On a separate note, I came across 2 different versions for the same crash ( Ecuador FAE 603 ALH Dhruv)
Version 1: HAL manufacturer says that the crash took place due to Pilot Associated Oscillations (Human error).

Version 2: Military Accident Investigation Board says that crash took place due to the presence of oscillations as the autopilot had malfunctioned.

Are they both right? Is one of them lying?
