Is that A340-600 in HKA colours outside HAECO actually belong to HKA?

No. Not a chance in hell.

could be here for maintainance but we all shall see ;)

It is ex-CPA B-HQC MSN475 that is being leased from ILFC to HNA.
It will remain outside HAECO for a few weeks awaiting a CAAC surveyor to come and do the acceptance to transfer onto Chinese register.

Busbert Has it 100% correct. Ex Cx 340-600 from ILFC being leased to Hainan.

Nice try Singa Snake Pilotinasia.

Stop chewing on your beetlenut. This forum is for TRUTHFUL threads.

If I wanted to laugh at the utterly riduculous, I'd sit on one of Wu-zy's "I've got thousands and thousands of hours" lecture. Your comment is beyond utterly ridiculous.
