The IGW of the newer AS350B3’s (dual hydraulic) is increased to 5225 lbs. (2370 Kg)
The 4961 lbs on older B2/B3 is a “hydraulic off” certification limit.
Interesting point made there. I always thought the 2250 was on the landing gear for safe auto's. So does this mean it's all to do with they hydraulic forces during a hydraulic failure? (seeing that technically the dual hyraulic system can't fail)
