Hundreds?? Well a few maybe but that is the same as the ones we see on the gates of our secret airbases - BER - cheaper to buy new than repair. Similar to trying to re-ferb a life ex CH47 - it is cheaper to buy new, the AH will be the same in Phase3.
The other point is they were left out in the weather for too long and may be a bit fatigued – most have had their spares removed and when the US tried to get 6 more – they were not available because they are so popular (
if you can afford to run them), they had to re-locate some of their trainers and are still short.
