What is the life limit given in Poland for your SZD? The FAA could limit your Experimental certificate in this way. A good example is the Sukhoi-26 I used to own had a life limit of 500 hours before an aircraft overhaul/life extension could be given. How would you like to send your aircraft back to the country of origin for this work.

I have not been through the entire 300+ page document and I do not think that the focus of this rule change is directed at experimental gliders but if they have the ability to limit what is stopping them? I work with some really great FAA personnel out of the San Antonio FSDO but they are always going to use whatever limits/rules that are detailed in the guidance.

I am looking at purchasing a Phoenix LSA and I am concerned that this rule could be a problem not only from flight restrictions (day VFR only / no congested areas/ other restrictions such as IFR even though the pilot is rated) but proving that the materials used to manufacture the aircraft is "in conformance" with US standards.
