Must have been a ride. If I recall there were a few others, but one hyd issue I remember is when the wrong switch over link was installed or was worn. Guy was flying at 500' when sys1 blocked due to metal contamination and during the switch over the collective dropped down. Needless to say he was pointed straight down and was a bit rattled when he got back. I member having to check the links as the ASB then AD came out and having to color code and measure them. I think after that there was a required switchover check.
