Well I guess that's one maintenance organisation Air Astana won't be using again. I wonder why they positioned the aircraft all the way from Almaty to Portugal and back for the check. Selected by the beancounters as being the low bidder ?
Air Astana from my experience (albeit only their 767s) came over as a pretty class act with traditional service standards, even in economy. Maybe not known is they are 50% owned by British Aerospace (that's BAe the aircraft manufacturer, not BA the airline), with some expat staff. So they should have more than a little background in aircraft engineering. The other 50% is owned by the Kazakh government.
