Thank you gentlemen for your answers and cautions.
I am aware that the subject is sensitive. I did not mislead you either.
I'm looking for, as part of an assignment I've been given, to write a set of rules around the practice of engine storage.
Having no experience on GE products I wanted to know where to find the storage limit information. I only find in the engine documentation a limit of 180 days without any additional information.
Knowing that there are experienced people on the forum I tried to simplify my task but you are right the OEM is the best placed to provide the information.
