91.205 also doesn't apply to gliders

Correct.
However, an FAA Inspector conducting a "ramp check" a/k/a "surveillance" in FAA speak may not recall this exception (that 91.205 applies to "powered aircraft".)

I've been ramp checked (friendly) a couple of times over the decades and what an Inspector who is not familiar with gliders may look for is a wet compass and the "compass correction card."

Other items are the weight and balance placards that have been rubbed off the cockpit side walls by your knees, the "TSO tags" on your seat belts and your parachute repack card. Some will look for the no-longer-required external data plate. Further, unless stated in your factory flight manual, the flight manual is not required to be onboard -- that's for airplanes and rotorcraft. Back to the factory flight manual -- what it states as required equipment may apply.

Interpretations may vary with FSDO's.
If ramp checked, be polite, especially when they ask for your medical certificate (USA.)
Consider investing in a good canopy cover!

"FAR part 61 shows how you earn your pilot certificate. Part 91 is how they might take it away."

Hope to see you at the SSA Convention in Reno, FEB 25 - March 1, 2014!
