Hi all,

I am interested in PTB and would like to do someindustry research. Specifically, I want to know more about who uses the PT6,TPE331, and T53 engines.
What do the planes that use these engines do(chartered flights / commercial flights / goods transport / etc.)?
How big is the addressable market?
What are the other competitors for theseplanes/engines?
Any information on this, or pointing me in theright direction for researching this would be greatly appreciated.
