This really is EC-EOX, but it has the tailboom of EC-EOI (c/n 408) as painted on the left side, but carrying fake registration N5028U on the right side, click here to see both sides. On the fin it carries EC-EOI's former US Army serial 62-1888. EC-EOI was fitted with another tailboom and by Dec-2016 it was carrying fake registration EC-TJF as an instructional airframe.
