“Only the Cessnas and Pipers are OK for continual banging onto the runway - not because they are particularly solid but because everybody can fix them, and if you have a fleet of them you can buy parts direct from the USA.”
The Robin (and the Jodel) has proved to be very long lived in the training environment, and spare parts for the airframe grow on trees. Before buying my DR400 160 I looked at the TB10 and it had very few advantages and a lot of disadvantages over the DR400.

Edited to add Robin/Apex are expecting to expand production of the DR400 this year as the ecoflyer version is proving very popular. How many TB10’s being produced this year?
