There is a new factory service bulletin about testing the spar caps of unmodified L-13 Blaniks to ascertain the quality of their metallurgy.

I'd say that if your L-13 passes the eddy current test described in the bulletin, all hope is not lost yet. The factory seems to continue its investigations.

I remember seeing one on the glider field at Sazena in 1997, along with a
hangar-full of assorted L-13s and an Antonov A-15 - in short, a hangar
full of metal aircraft.

Stick an old motor (harley davidson?) on the front and some R/C gear in it
and flog them to military as drones or targets

"Finding nonconforming mechanical characteristics of
the material on the L13 Blanik sailplane in operation"

That sounds new and ominous to me.

At around 2000hrs. total time: hold on to it and wait for the AD&C mod to be approved by the FAA (like it has been by many other national airworthiness authorities) or sell it very cheaply to someone in a country where it has already been approved.



If it's at more than 3000 or 4000 hours already the flying life given by the mod probably wouldn't be economically feasible given the cost versus remaining flying hours.

The last word from the FAA which was obtained by the SSA indicated that it would be a real stretch if the European fix will ever be approved here. To compound the problem it looks like there would be more questions about the rest of the aircraft's life expectancy since the wings that broke were not near the 5,000 hours. Don't think a large number were repaired in Europe according to my inquiries when there last spring.



If it's at 5000 hours (or more) - scrap it after pulling any good parts off of it (oleo, wheel, instruments, possibly some miscellaneous small parts). 5000 hours is the current maximum authorized total airframe time with no further aerobatics even if you put the $12-15K into carrying out the AD&C mod.



Following the factory's website I don't see much hope for them coming up with an alternate solution anytime soon.

Like about 300 US Blanik L-13 sailplane owners, I have a ship that will probably never fly again. Just trying to find out what other owners are doing with their hangar queens. I know of one where the owners took it apart, separating the aluminum from the steel for sale to metal recyclers. From what I heard, the time and effort involved put their hourly income at about half of the min. wage level.

Not many museums want one and tad big for a wind vane. realistic ideas?

I'm modifying one to a motorised configuration - but AFTER incorporating the life extension STC modification

The Southwest Soaring Museum in Moriarty, NM, USA will be putting an HP-11
on top of a pole any day now. It will be free to rotate into the wind.

Maybe you *can* still use that L-13 for a similar project, though hopefully,
it can be restored to flight.

Many "cockpit builders" are looking for real cockpits to convert to a realistic flight simulator.
