Absolutely agree that the provisions for supervision of inexperienced instructors starting work at a new organisation are not very good under JAR-FCL. That accident led to an AIC on CFIs checking out new instructors, which is tackling the issue at a broader level, not just looking at inexperience on a particular type. In my view it makes sense to deal with it at that broader level rather than having mandatory previous hours requirements on particular types. And it also makes sense to place responsibility on CFIs to ensure that proper supervision is given.
