Technical Data / Performance/ HistoryThe original L-13 BLANIK was built by the LET factory in 1958. Since then almost L-13s were made, and many of them are still flying all over the world. The two-seat, all-metal L-13 became very popular due its durability, reliability, and ease of handling.

The fuselage is of semi-monocoque construction with longerons and
bulkheads, oval in cross-section. The cockpit is covered with a
one-part plexiglass canopy. The rear fuselage is made of two stiffened
semi-monocoque
structures and reinforcing bulkheads riveted together.
WINGS
The trapezoid-shaped wing with a negative sweep is of all-metal,
single-spar construction. Each wing half is connected to the
fuselage by means of a vertical main spar pin and a horizontal
front spar pin. Flaps and ailerons are of metal structure, fabric-covered. The spoilers
extend both above and below the wing, and hook up automatically.
TAIL
The horizontal stabilizers of all-metal construction attach to
the fuselage at the base. The elevators area of metal frame covered
with fabric, and each has a trim tab. The elevator and tabs
hook up automatically upon assembly. The rudder's metal frame is
fabric-covered and attaches to the all-metal fin on two mounts.
FLIGHT CONTROLS
The control sticks actuate the elevator and ailerons via a system
of levers and rods. The adjustable rudder pedals are connected to
the rudder by cables. The elevator is aerodynamically trimmed. A
system of levers and torsion rods extends and retracts the
spoilers. The L-13 is equipped with a front aerotow hook and side
winch/auto tow hooks. A custom, bottom center of gravity tow hook
may be built in. Both tow releases are controlled by handles on
the instrument panels.
LANDING GEAR
The landing gear consists of a semi-retractable single wheel,
equipped with a drum brake, and sprung by a well-proven
oleo-pneumatic shock absorber. The front bottom of the fuselage
has a protective steel shoe. The reinforced, fully-swiveling,
solid rubber tail wheel has a rubber shock absorber. Optionally,
a tail skid may be installed.
COCKPIT
The cockpit can accomodate pilots 5'1" to 6'8" tall.
The four-point seat belts protect the pilots along with
upholstered seats. Two full sets of
instruments may be installed. The variometers are attached to the
total energy probe mounted in the front. Fresh air can be let in
the cockpit either through the front fuselage vent or through
sliding window scoops.
The L-13 is a very enjoyable glider to fly. The take-off roll is smooth even on rough ground thanks to a very effective shock absorber on the main wheel. On tow, the aircraft is very stable and can be flown hands-off when trimmed with the responsive and easy to adjust elevator trim. The controls are accurately tuned and balanced, and move lightly with little friction. The fore-and-aft stability is excellent with no tendency to over-pitching. The lateral handling is very effective with a roll rate of 4 seconds from 45° to 45° at near the best glide speed. The airbrakes are effective and gradual in application. Side-slipping is excellent.
On the ground the glider is very easily maneuverable thanks to the swivelling tail wheel and optional wing tip wheels. If tail lifting is required to move the tail over especially rough ground, the tail may be handled by inserting a bar just ahead of the vertical fin. The one-piece canopy closes and opens from either seat.
History
In
2010, the FAA grounded the operation of L-13 Blaniks. In July 2017, the
