That's a tough decision. Do you sit tight and wait for help as long as necessary -- knowing that if the aircraft falls from the lines you did less than everything you could to save yourself? Or do you unbuckle and try to help your situation? What could one possibly do for themselves in that situation? Lots of reason to believe that the pilot wasn't in a frame of mind to aid his rescue even if help had arrived. Aside from the fact that this happened in a rural part of NE AR, the terrain alone even in more populated areas underlying high tension power lines could be prohibitive in getting rescue equipment (boom crane with 150' reach?) on scene. There's a reason lots of pilots built their hours patrolling these sorts of infrastructure -- the utilities couldn't do it cheaper on the ground.
In this case, the report says that the pilot survived the initial wire strike, which suggests that he was at least communicating with someone, and would have an idea that help was en route, even if he didn't know when it would arrive. The rescue helicopter dispatched four hours after the incident, but knew to turn back after just 20 minutes? Where was it coming from? Little Rock is about 70 nm SE of Batesville.
Sad in several ways, not least of which was to have the pilot survive the impact, but die from the crash anyway. I don't mean this to sound glib, but anything you do can get you killed, including doing nothing.
