Since ELA2 is max MTOW 2000kg, the associated alleviations do not apply.
well… in theory a 1999 kg Jetprop would be ELA2?
in the case of TBM, it is way over 2000kg….
ELA2 is not applicable to N-reg. A TBM could certainly be run on FAA Part 91. The advantage would be not so much on the engine maintenance (which I guess would not change) but on everything else which is pointlessly done on the Annual (see the link to the other thread).
The PA46 and the TBM seem to be maintained very differently even though their systems are similar. For the PA46 I think most turbines are run on condition past TBO besides much other maintance on condition. You see more and more Meridians for sale over TBO etc. Also except some brand new M600 nobody seems to be on any engine programms etc.
On the other hand it seems to me that most TBM owners maintain them like a jet. I have no answer why that is the case but it seems to be a tradition, owners maintain planes in a certain way, they buy the engine programms, the used market expects the planes to be maintained in that way, the maintenance companies do it that way and the circle closes.
After all the main reason to buy a PA46 turbine is money. If it was no issue at all 90% of the ownera would probably get a TBM. But the PA46 forum is full of owner reports who did usually retire and then sold their TBM in exchange for a Meridian or similar as they could no longer justify the cost of the TBM.
