The HN title is literally the subject of the notice, very slightly paraphrased (abbreviations expanded, etc), so you may want to let the FAA know they got it wrong...

I also think you misread the notice. The report is stating the loss of GPS apparently resulted in the subsequent loss of a number of other systems, including the yaw damper.

I think you're right. The wording about "no yaw damper" would have been clearer as "failed yaw damper" - I guess that's what was meant.
