and this question from the author of the above PDF:

Hello,
Does anyone know Detail Information on Blaník which have been modified to
L-13 Type A1, the so called "Llewellyn Modification"?
Even information on the Aeroclub that does this Modification or contact
data, also the name of the Aeroclub would be very helpful for me !

Happy landings and Best Regards!

Could anyone advise the current situation in USA, Canada and Europe regarding the grounding of L13 Blaniks ?

Have many been put back into service as a result of satisfactory wing spar inspections, or do most remain grounded due to the fact that the required average usage statistics required by LET cannot be met, and with respect seem most unreasonable.

For instance – what two seater training glider (or for that matter any two seater glider) would have an average of 35% dual and 65% solo usage! More likely, greater than 80% dual would be a more realistic figure I would have thought.

I haven't heard that the FAA has issued an airworthiness directive
yet, so no L-13's in the USA should be grounded.

Ours was inspected per the bulletinby 2 IAs (concurrently), deemed
airworthy, and signed off. We're flying it.
It had just been down for an annual when the bulletin was released.

Same story for my club, almost.

We pulled the wings and inspected everything and it went fine. Ours is
heading into annual next month, but we didn't want to wait.
