HAECO
Yup, the canteen is something else, the tea is good, particularly if you like it strong with condensed milk. I worked there some (10) years ago. The reason they are a major maintenance hub is low price of course. As I remember there was a lot of semi skilled unlicensed labour and my key role was supervision and signatory.
I am now longer in the avionics engineering sphere, as I found the pay (generally, not just HAECO) non commensurate with the tasks and responsibilities involved. If you are young and want a taste of the Orient do it for 1 or 2 years and move on, Honkers offers a lot of experiences outside of work, and is in IMHO one of the best places to live in the far east.
All the best in your endeavours.
