I seem to remember reading SOMEwhere that Rotax (or perhaps a maker of some standard category SLSA with a Rotax 912) allows an on-condition inspection in place of a mandatory rebuild at the official TBO hours.
If I remember right it was a serious inspection, not at all cheap, but still much cheaper than a total overhaul or engine replacement.
Can anyone confirm this and/or get or point to details on this? If it's true, when it applies, what's involved, what this on-condition inspection might cost? And would it have to be done, for example, again every year or at some stated interval?
Reason for asking is, it's well known that there are many Rotax 912s which if well maintained, not abused, are far from actually needing an overhaul at 2000 hours. In experimentals where they are not required to overhaul at any particular hours it is not unusual, IIRR for many to go 4000 hours of more.
So to an owner, or potential buyer, of a SLSA with a 1000 or 1500 hour 912 in it, it would be very useful to know if an on-condition inspection could even potentially be done instead of an overhaul when it hits 2000 hours.
