I couldn't find much info on who Ecu Air were. However, it is believed that it was connected to Air Ops. This frame has a lengthy history. Suffice to say that it was ex TWA N31033 and SE-DPP with Time Air Sweden. Went to Royal Airlines as C-GRYU and Air Atlanta as TF-ABD. After that it went on to fly for several distant and exotic operators until it retired in Aug 2010.
