I'm familiar with most of the PT6A variants, but I've never heard of a "PT6A SER", unless it's being used in a generic sense to mean all PT6A series, in which case it's meaningless to talk about performance specifics.

52257 is the normal 114A engine model no , 52032 is the SER engine model.
Pratt does not give any info on this PT6A engine.
I just like to know what I am getting into flying this engine.
Thx, R

QED.

Call your local P&W service centre, quoting that serial number, and they will tell you what series the engine actually is.

Hi Richard

Just want to find out if you ever managed to get info on that engine. We running a King 200 with them and would like to find out what you think about the SER.

The 750hp PT6A you are asking about is a -135A.

"SER" may stand for Service Engineering Request - perhaps newly-certified, upgraded hardware (turbine?) installed on a limited basis (perhaps at no cost) in certain customers' engines for field evaluation.

If the SER proves successful - meeting design objectives - the new hardware will probably be released for unlimited use.
