Dear aviation friends,

my name is Pavel Rind and I am representing an approved maintenance
organisation for L 13/L13A/L23 and L33 gliders produced by former LET

UK from 11-15 th March 2011 and we would like to inform all owners and
operators of Blaniks that we can provide the following service free of
charge on your airfiled:
-check of current technical condition of these gliders,
- technical advice
- or any other support you need.

More information about our company and our works can be f

You're kidding us right? (You seem to be overlooking just one teeny,

Perhaps he's from that 1 country that didn't seem to get the memo...

he was talking about an L23 they inspected......
and for what I understand the L-13's are flying in the Czech
republic.....it's the rest of the world that is waiting for the official AD
resolution....
Gliders with a "known" history can be returned to service with factory
overhauls (as they do in the Czech republic) and with complete
records...those with sketchy records and dubious maintenance are the ones
that are causing the manufacture and CZ FAA the concerns......
and will be the cause of whatever additional inspections are necessary to
prove them airworthy..

Has this happened in the USA?

How much $$ for a "factory overhaul"? What is the turn around time?

Is the "factory" doing overhauls?

No, the factory is not doing any work, nor supplying parts directly.
We need to band together and buy the TC a la Eclipse. Not likely,
IMO, based on the response on this board and the FAA comment page..

I believe there used to be a program where you sent your L13 to the
factory and got it back with zero timed wings.

No longer available as the manufacturer is concentrating on 40 year
old designs...

This is a 1956 design - pre Finite element analysis and CAD and all
those other things.
It was designed to build using the abundant cheap, skilled labour
available in the Soviet Union. I assume the factory stopped the rebuilds
because of simple economics...
You have to question whether it will be economically viable to keep
this fleet flying.

And - yes I have many hours of "unusual attitudes" in an L13, and it was
a lot of fun, and a good intermediate trainer. Wayne and I once did 11
consecutive loops at the end of a little cross country. But there's the
trouble, I doubt our club L13 had many flights that did not include at
least one steep turn, or chandelle, or whatever. That makes them all
aerobatic time - so the glider is scrap, under the current AD...
I would love there to be an economical way to return them to service,
but am not optimistic.

amazing how few owners know about these, or if they know have ever attempted
to accomplish them.....pretty easy to hide from your local mechanic who is
doing the paper annuals too.if he doesn't research the glider documents he
won't find them and simply sign off the log book as being "airworthy".this
isn't just the L-13 Blaniks, I'm in constant amazement of how few know or
actually do what is required to maintain an airworthy glider....the TCDS
lists the basic requirements, the operators manuals and "supplementary
manuals for "tem limited" parts are supplied from the manufacturer..these
dictate most of what has to be done at " time " intervals.....
Most Blaniks had a 2000 TT limit when new, at that time they were "run out"
and no longer airworthy....but, if they were overhauled they then had
extended life limits, typically another 500 hours - 1000 hours depending on
which overhaul was accomplished....and so on...in Europe they could be
returned to the manufacturer, or to one of their approved repair
stations...here...you can buy from Blanik America the technical notes that
outline the overhauls, tough these were from the Australian aircraft
authority and then accepted by the US and recognized by LET as documents
outlining the overhaul procedures (contact Blanik America to find out more)
I believe the problem exists with the current AD because there is
insufficient data on many Blaniks and poor record keeping so the
manufacturer has no way they can simply come up with a blanket fix for
all....those with proper history, known history of the types of tows, number
of aerobatic hours ect. Blaniks in the Czech republic (I have to say that
they tend to take maintenance far more seriously there than the average
owners in N. America ) are typically well cared for, well maintained and
well documented....and for this the manufacture can take what data is
presented there and make the assumptions of what is needed to return each
one to service.
This may be a Blanik concern today but it doesn't mean all other gliders are
immune.....we need to start taking maintenance issues far more seriously
here.
contact Blanik America, he can get you the overhaul proceedures

I sent in e-mail to Pavel to get his take on the L-13 Grounding...
here was the response:

Hi Tim,

Thank you for your email.

Yes, we are in close touch with LET and at this moment the new
inspection
method is developed and all documents and details about the wing root
area
inspection were sent to EASA for the final approval. If everything
goes
smooth we expect that at the beginning of March more information will
be
released.

The new inspection will be based on eddy current waves and should
allow the
check of wing root area without opening the wing.

When I get more information, I will contact you.

Thank you.

Best regards

Pavel Rind

I don't need an L13 inspection but can I book this guy to do some
stand up comedy for our gliding club?
