This single accident raised a lot of issues. All inter related and all significant.
Agreed - if you had a known or suspected collective issue, wouldn't you be extra vigilant knowing you had selected a cyclic mode (VS) where power controls speed? he seems to have made a power adjustment at 80 Kts but not looked to see if it had the desired effect of stablising IAS.
Personally I dislike CDFA profiles - may be my age - but the ability to level off at MDA and run in until the MAPt is ideally suited to helicopters in marginal conditions.
The fact that they managed the 'L2 tail slide' without using ALT.A speaks volumes for the lack of CRM.
