The L 23 is an all-metal, two-seat, self-supporting,
high-winged glider. Due to its all-metal construction,
the glider is guaranteed a service life of
6,000 hours assuming that mostly ground-launching
is used. With mainly aero towing used in North
America, the service life may be extended to
well over 10,000 hours. The L 23 has been approved
for all stages of flight training from basic
to advanced cross-country, aerobatic, stunt,
and instrument flying.
