When I started flying the Puma in 1971 its MAUW was 5,800 kg. The soon went to 6,000 and then 6,300 with a 40 degree bank limit. The J model with plastic blades went up to 6,500 kg.
The 332, effectively the same rotor system with enhanced engine and gearbox went up to 8,500 kg almost immediately increased to 8,600 kg. I operated the 332 L1 in the Solomon Islands at 30 degrees temperature and zero wind at an underslinging departure weight of 9,100 kg.
The 225, still much the same concept as the original Puma has started off at 9150 kg.
