HZ,

Being an owner of an "Experimental - Homebuilt" I'm not totally competent with the exact differences; however, here are a few things I do know.

In the "Homebuilt" category, if you built it, you are granted the authority to perform the annual inspections. If you are a subsequent owner the yearly condition inspection must be performed by a FAA licensed airframe mechanic.

The "Experimental - Racing/Exhibition" are similar in the requirement to have an airframe mechanic perform the yearly condition inspection. A airframe mechanic must also verify that the aircraft in compliance with all factory safety bulletins.

The "Experimental - Racing/Exhibition" classification is quite common in the USA. Our field has two ASW-27A, a PIK-20 (Serial number 2) with this type of airworthiness certificate. In the past our field has been home to several other "Racing/Exhibition" sailplanes including a ASW-20A and Diana.

Just a small correction. The USA Experimental category of a Diana is "Racing/Exhibition" not "Homebuilt." There is a difference.

To be considered "Homebuilt" at least fifty percent of the construction must be completed by an amateur builder. Normally this means the aircraft is delivered as a "kit" and assembled and flown by the builder. However, many have been built directly from a set of plans. (Woodstock, Duster, Tern, BG series, etc.)

The most popular US "Homebuilt" series of sailplanes were designed by Dick Schreder.http://www.soaridaho.com/Schreder. I fly one; however, I am its' third owner and wasn't involved in its' construction.

If the glider is without EASA Certification it is general rule. But I
think in USA it should be different. What I know all Diana's are there
flying in Experimental category. It means as "home build" gliders and
the responsibility is on the pilot.

Thank you for correction. They informed me as this in factory..

Please, how it is with this "Racin/Exhibition" Category? Who is
responsible for glider? Also and "Operator" or only pilot, means
needn't a operator.

Thx, Hana
