It could, but I don't think he would have been able to flight the extra mile to the accident site. However, if it had and he flew it that way then the appropriate warning/caution lights will be seen in the download. The only hydraulic issue I recall in the past is a tie-bar breaking in the LH EHA on a 135 hovering in the Caribbean. The cyclic motored aft resulting in the pilot dumping the collective and a hard landing.
