Hi Ian,
Seems according to TECNAM and Solo Wings the answer is yes. Our Tecnam P92s has a 912 ULS with about 850hrs. We thought when we bought it that it had 2000hrs and would see us out. Now it seems it has 1500 BUT a calendar TBO of 12 years. Currently that gives us another 18 months but we never knew about this and to say we are pissed is an understatement. Also there is a Service Information Letter (SIL-2016-01) issued by TECAM Jan 6 2016 for Oceania engines that changes the mandatory calendar TBO to recommended. BUT apparently CAA in NZ are ignoring this. Please have a look at a Face Book page we have set up to try and organise NZ owners. Please spread this about. We need all ROTAX owners to be aware but we thin many aren't. Rotax New Zealand Owners
