Andrew,

Regarding specifically Experimental Exhibition and Racing certificated
gliders that were certificated after July 19, 1993;

Take a look at The Order 8130.2F, CHG 3, Paragraph 161. subparagraph
(37) (page 178) regarding the annual program letter requirement. Looks
to me like if you just do proficiency flying all summer and don't go
to a "sanctioned meet", you might be OK with your original letter. Of
course, per subparagraph (34) that pro flying takes place within a 300
mile radius of your home base airport. Subparagraph (35) is also
interesting reading, but in any case, all the paragraphs have to be
read together in detail ad nauseum to make any sense - and then we
realize we are reading FAA guidance, so making sense may not be the
preferred task outcome.

Don't forget your copy of the "highlighted aeronautical chart" that
you carry with you aboard the aircraft per 161.(37).

While paragraph 132 may appear to be in conflict with the above -
we'll just go with the guidance specific to Exhibition and Racing
certificates, and even more specific to Group 1: Performance
Competition Aircraft, which iswhat the racing glider is defines as by
the FAA..

Paragraph 155.(c) (page 166) states that when the aircraft's base of
operation is changed or a change in ownership occurs, the owner must
notify the local FSDO and provide a copy of the inspection program (if
applicable, not likely for a glider, unless it's a turbine powered
glider) and a copy of the requested proficiency flight area.

Call your local FSDO for guidance specific to their area of operation.
Some FSDO's and aircraft Ops Limitations differ because The Order
allows it, see Paragraph 161, suparagraph a. (page 172) where it
states "The FAA Inspector may impose any additional limitations deemed
necessary in the interest of safety."
