Yes, both of you! Nice picture of an Air China A340 in the midst of a 8C-check at Ameco Beijing. The work included a major structural mod that involves removing the fin as you can see. When it all gets put back together it looks like the bottom picture. Ameco Beijing is an Air China – Lufthansa joint venture and a truly noteworthy success story I’d suggest. They say they did five of these checks last year.
