It is true that the answer varies greatly depending on country / type of operations. According strictly to JAR-FCL, I'd say:
- Largest single-crew twin: Beech 1900D @ 7781 kg MTOW. If we start talking single-
pilot airplanes, in the old days the Canadair CL-215 would be one of the biggest @ 19730 kg MTOW even though it was operated with a pilot and a mechanic (just like the DC3s and DHC4s).
- Smallest multi-crew twin: Cessna Citation 500 @ 4920 kg MTOW. Talking turboprops, it's gotta be the Let 410 @ 6600 kg MTOW. Much smaller than the Shorts 330 which weighs over 10 tons!

According to the "new fangles JAR thingy", which I am afraid has been implemented for quite a few years now and applies even to Scotland
:
• Perf A = Multi-turboprops with MTOW > 5700kg or capacity > 9 pax & all multi-turbojets. This would include larger King Airs and Twin Otters.
• Perf B = Propeller airplanes with MTOW ≤ 5700 kg & capacity ≤ 9 pax.
• Perf C = Piston airplanes with MTOW > 5700kg or capacity > 9 pax.
