Does anyone know of an aft tank one-time mod that was done on a short body MU-2?
Probably less than 5 planes have the mod.
IBA installed it, but doesn't any more (out of business?).
You had to watch CG with it full, could put you out the rear CG limit.
Would give you about 120 nm more range.
With my M model, the book tank capacity was 366 gallons but I could put about 385 gallons in it if you absolutely filled it to the super top slowly. I called this a "super fill" and had to be done in a proper order. Main technique was doing the center main ports multiple times and getting it to the very top.
Some planes have a drain that is activated by the cap being removed. Mine was plugged and that's how it should be. The drain does nothing except make a mess.
With about 20 extra gallons, you get about 90 more nm.
