My point is this. These types of approaches are statistically way less safe than a conventional ILS. If you apply TEM, an NDB should be at the very bottom of your list of preferred approaches.
If You apply TEM You can safely fly an NDB approach when no better approaches are available, such as ILS, RNPs, etc..
From what I have understood out of this report, the crew was not sure whether they were allowed to fly an RNP approach at Bergerac (knowledge problem within the crew ? Company information confusing?) and hence reverted to the NDB which was also mismanaged. The consequential errors were finally mitigated by the crew reacting appropriately to the EGPWS warning.
