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

Has this happened in the USA?

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

Is the "factory" doing overhauls?

Gliders with a "known" history can be returned to service with factory
overhauls (as they do in the Czech republic) and with complete
records...
