EASA has now published an emergency AD (saying essentially the same
thing as DG's Tech Note), available at:

http://ad.easa.europa.eu/blob/easa_a..._2007-0100-E_1

I know about this only because a friend saw the link on the BGA
website.

As a long-time DG-300 owner, I am extremely disappointed to have heard
NOTHING from Glaser-Dirks about this situation. There is simply no
excuse for this. They have all or most owners' e-mail addresses
already (for their monthly newsletter). This situation cries out for
proactive announcements, explanation, clarification, etc. from the
manufacturer. Instead, we are left to scavenge whatever "information"
we can (possibly not all accurate) from R.A.S. and other sources. DG
did put the Tech Note draft on its website last week but that helps no
one unless they know about it or accidentally stumble across it. What
is missing is any official notification from the manufacturer. I can
abide the limitations required by the AD more easily than I can this
pitiable lack of proper communications and support from Glaser-Dirks.

Almost two weeks ago, when the R.A.S. thread first appeared, I sent an
e-mail inquiry to Glaser-Dirks with copies to the North American
dealers. I received no response. No excuse for that, either.
