In the US, there would not be a question of spares support, but there is in Iran. The embargoes are, no doubt, a factor, whether you or I agree with them. In Iran, there have been questions about airworthiness in past, far too many, crashes. So, yes, it is a legitimate question, if very speculative. But when has speculation not taken a backseat here at Pprune.
