Seeking "hands-on" feedback about operational and engineering aspects of the the Xian MA-60.

Greetings to Flightglobal members and visitors from dakota67.

I am acting as an advisor/consultant to a projected "start-up" part 121 airline that intends to operate in an equatorial nation that has several quite high density altitude airstrips. So was wondering if there might be some engineers and pilots who have "hands-on" experience with the Xian MA-60?? Of course we know a great deal about the An-24 and An-26 which have a very long history. Whilst the MA-60 is already operating in several African and SE Asian states, it would be a first-of-type in the country(s) we are dealing with. I and my associate team leader have had considerable experience with the Fokker F-27-200 which worked very well in the equatorial environment; albeit with some manageable take-off weight restrictions at hot-and-high locations. We are of course interested in the realistic values of single-engine service ceiling and drift-down rates of descent with one feathered. As you will know, there is nothing quite as valuable as listening to people who have flown or maintained an aircraft type in the field to garner a picture of a machine's good or not-so-good characteristics....thank you should you be able to comment.
