Hi all.

I listened from some pilots that the glider life hours reduce if you
use winch start.

Is that true? I looked for some data about and I did not found.

have a nice day, José.

Any life adjustment issues should be in the POH or the maintenance
manual. There were adjustment factors on our L-23 for winch launches,
flying with the wing tip extensions, solo/dual flight, or for aerobatic
flight.

Hi Frank,

Thanks for reply, L-23 is an special situation with the AD in the wing
roots.

What about K-13, Ka-6, Libelle, Std Austria, Lak-12, Std Cirrus,
ASW-20...

There is nothing my Std Libelle's POH about launch method affecting
airframe lifetime. AFAIK they are fitted as standard with both CG and
nose hooks. Mine was, and so are the other two others based at the club.
Re-life inspection is at 3000 hours regardless of launch method.
