Diana-2 and overall performance discussion

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

Well, your English is much, much better than my Polish, so I'm not
complaining! Thank you for the comprehensive explanation.

PS. Jacek Kobiesa just wrote on Polish forum that my English is not
best and Polish as well, that I didn't understand his words here... My
English is not best, Polish a bit better and I am understanding the
meaning.... It was written as in main origin of Diana 2 technical
documentation which was in English and understand by English (If
Australian) engineer, that that Diana 2 is with certificate. So
question from Mike was: Why we have to do an experimental
registration? *HZ

Be welcome Martin. Have here nearly ready some views for Paul.

I think Jacek Kobiesa likes only to say that his English is better
thaty my one. I am originaly Czech and they don't like when I am
writing in English because not only Polish can read it

Still have messages in my mail box from Polish, who are "normal" means
healty so when somebody is giving me offence I am not worry because
of it

Hello Paul.

I found some documentation and details on web:

http://en.wikipedia.org/wiki/Experimental_aircraft
page 9

http://www.easa.europa.eu/ws_prod/c/...ro/eu_prod.pdf
page 22

http://www.easa.europa.eu/ws_prod/c/...o/easa_apo.pdf
page 72

http://www.easa.eu.int/ws_prod/c/doc...planes_EUR.pdf
page 1


Here is the Diana 1 EASA Certificate.
http://easa.europa.eu/certification/...1-28032007.pdf


Talk about this Diana 2 VH-VHZ s/n 3 case in 2008 year...
http://www.szybowce.com/news/article...p=ava.szybowce

In Polish on the top is written answer to somebody on Gorpol's forum
via Gorpol, who is friend of Beres.. He explained the Diana 2 case by
way, that faults did Australian engineer. Here what they found at
Bielsko aftere handover. Hope you are a bit experienced technical and
everyone can imagine what about it was...

http://www.aviationkb.com/Uwe/Forum....a-2-in-service

Any question to this welcome

I found this as well http://newsgroups.derkeiler.com/Arch.../msg00313.html

The talk was originally about Diana 2 and difference between position
of wings was in case Diana 2 s/n 000 factory prototype “BB” (which
gave me to fly Beres with 15 kg of ballast under seat) in 2005 and
others production numbers as my s/n 003.

It means not confirmation between wing position of Diana 1 and Diana 2
wings. Of course, they are different... but the some fuselage.

Thanks to all of you for your interest and internal posting.

Cheers, Hana
