Hi Roscoe,and all,
My AA1C has the STC for the 0320E2G engine SA2477SW
As the Max TOW is currently 1600lbs, i am seeking information of any previous STC which allowed an increase in MTOW to 1683lbs

I am seeking approval from Australian CASA to operate the aircraft to 1680lbs, so any previous STC paperwork for a weight increase would be very helpful in supporting my engineering submission for a stand alone new approval.

I believe there was an STC for a weight increase to 1683lbs associated with an aux tank mod. Would anyone please have a copy of that approval?
I believe the owner of that STC has past away and his family are not contactable.

Thanks Sonic
