IMHO it is impractical to expect "drills" to be produced for every eventuality
It's not a matter of different eventuality but basic fundamentals. Losses of thrust during initial climb requires to control:
- Safe flight path
- Optimum speed
- Configuration (drag)
There is basically no difference when this happen during an approach, there is no need for a "special" procedure. I regret that the AAIB didn't consider including few lines about it.
