However, my understanding of the m ain issue with increasing the MTOW is demonstrating the landing gear is c apable of withstanding the additional loads, potentially with prop cleara nce issues on the mono in addition. > > > > RIchard > > > > Sent from my iPhone > > > >> On 15 May 2019, at 08:39, John Wighton wrote : > >> > >> --> Europa-List message posted by: =22John Wighton=22 > >> > >> Quote: > >> > >> Here in Canada we can declare whatever gross weight we want (wisely or > >> not).

Th e goal therefore may have been to match the standard a/c stresses. I have some of Jason Russell's work on file from many years ago, it is probably worth taking a look at that and any other design data (at LAA=3F) to see what the margins are. > >> > >> I suspect that the long delay in gaining approval for the MG versio n stems from a reduction in structural margins.
