It seems to be willful ignorance. Basically ignoring the customer to continue pushing the line that the problem was due to training or maintenance.
Boeing did the same with the 738 Max, they attempted to blame Lion Air on poor training and maintenance when it was the MCAS. They couldn't continue with that lie when the 2nd plane went down in Ethiopia five months later.
With military airfcraft, the safety threshold is probably far lower. This Dhruv/ALH helo had been grounded repeatedly from earlier crashes. The entire fleet had been grounded so far this year.
Unbelievable that seriously deadly issues over a decade ago have not led to a safer aircraft today. When you lose 4 out 7 to an export customer, it should have started ringing bells at the corporate level.
