Please send me contact information.

I'm doing some research into availibility of repair stations or shops
that do composite major repairs and besides the obvious ones - Rex at
Williams Soaring, John Murray's shop, M&H, Chris in Arlington and all
the others listed in the Soaring classifieds, but I'm not having much
luck. I thought there would be quite a few composite shops with all
the new glass power planes out there - and I'm sure there are, but
there's no listing of small aircraft or glider composite repair
facilities that I can find. Plenty of composite shops for your 777 or
A320 elevators, but those guys won't, and probably cannot, do your
glider, or specifically this AD.

The FAA's repair station query is next to worthless on this subject:http://av-info.faa.gov/repairstation.asp (Try searching all states
for Limited airframe or any airframe)

I'm going to keep trying and maybe somebody here has knowledge of a
list other than the Soaring classifieds (EAA maybe) - but at least
those guys are a start, but usually, days away from where you are,
unless you're very lucky. Canadian AMO's can work on your US
registered glider - if there are any Canadian glider repair AMO's -
that may be helpful to somebody.

I would respectfully submit a minor change to your statement Todd. Why
did Grob wait so long to recommend this become an AD? Note Grob's
position statement in the information provided above:

"Grob's current position is to recommend that the FAA issue an AD
using the original service bulletin with adjustments in the time of
compliance."

Hopefully, it's a big adjustment to the time of compliance. There is a
procedure for Alternate Means of Compliance and an Adjustment to the
Compliance Time for any AD, this one might be a good candidate for an
AMOC if the compliance time falls in the middle of June, but I doubt
it will be that soon.

I saw a reference to a repair team in one of Bob Kuykendall's posts, a
team that did the 103's, but I suppose those were Grob guys Bob?

Jim,

My current focus is to try and find a shop that has already done this
work on either a Grob 102 or 103. This will give us a real idea of
how much it will cost.

Grob Systems is shut down.
Gehrlein Products never did it, they referred clients to Grob Systems.
XU Aviation in Canada did one at least.
M&H never did it.

On the time of compliance. I do hope that with the lack of any
problems since the original SB, that there is no urgency to issuing
this AD and they will set a reasonable method and time of compliance.

Contact Robert Mudd in Moriarty, NM. I know that he has done at least one
of them.

Thanks, I will call and talk to him. It's a long drive from
Connecticut to New Mexico though.

Todd,
The work must be done in a FAA certifid glider repair station, like
John Murry's or Gehrlein in your neck of the woods. it involves about
20 hours of work + the cost of the kit from Grob. It involves
assembling the ship with wax donuts on the old spigots to determine
the excess lateral slop that must be removed when the new spigots are
installed, then grind and remove the old, then fit the new with
factory jig, scarf spar but and lay up 8 layers of 92125 for the
replacement spar wrap. I would estimat $1800 to $2400 bucks.

JJ,
Would Rutan style 7725 be a similar cloth to the 92125 European cloth?
Thanks,
Brad

Yep, but when working with certified aircraft like the 102, one must
use the specified stuff. The kit I got from Grob had per-cut 92125
sections, everything but resin...............BTW, Williams Soaring
(Rex) just got 50 gallons of L285 epoxy at half the price that Spruce
& Seciality is getting.

JJ,

Thanks a lot for this information.

It was a factory supplied jig that was used for the replacement ?

Todd, Did you happen to notice the 3/21/05 response date on the
Airworthiness Concern Statement?

Yes, at least after it was pointed out :-) I think that there might
be a typo. The real deadline for comments in May 11th, I think.
