sorry couldn't resist the laugh.
I can't believe you ask this on Pprune??
Surely if you are in a position to acquire two VERY expensive Aircraft then you'd have the ability to go through "proper channels" to obtain the info......
Maybe try ringing up a few maintenance organizations in Hong Kong or Singapore or Manila to ask them???
There's an idea
Besides all that I'd be more worried about the Airworthiness of these two Aircraft first........
