I think the dynamic components were 100 pct france.
China built the fuselage and Im not sure what the other share was.

jack stall or control transparency, whatever
 

One of this days i was type training a pilot and since he was for firefighting directly on the 350, we trainned some emergencies as far as close to real. the first time i saw a real HYD light was during that training sessions, after i chased the cause and looks like with low G or when one hard land and go up in the sky again is possible to have that red light. And maybe there´s some persons around that don´t pay the attention that they should pay to hidraulic acumulators, as i have seen in some type examinations.
Well to considerations, if one have servo transparency is because hyd power is no more capable of sustain the loads transmitted by the blades, decrease load factor on the rotor and almost immediatly everithing return to normal. Second one should not confuse jack stall with hyd failure due to low G ( happens that the system is like that and the hyd pump can suffer from oil starvation, conducting to a real hyd failure), if one have that situation and the power acumulators are in bad shape well is like having hyd failure. the hyd pressure takes a wile to return, wile enought to waste hyd acumulators if one does not stay cool. my advice is to study the situation when that happened, and published it here.
almost 1000 h on 350´s and never experienced jack stall , even to show to trainees.
good flights
