I can just imagine the guys back at the Sikorsky factory trying to get their heads around this. The system was designed and built by the previous generation of engineer/designers so in theory the current generation bear no guilt - if there is guilt to be borne. But would they be wise to come forward and admit that the hydraulic system has a fundamental design flaw? Can you imagine the fall-out that would accompany such an admission?
Can I ask you (Copterline) what Sikorsky have replied to your assertions?
Aye
