Following
the factory training of your technician, it is possible to send a
Blanik factory technician to your facility (for example, for one month)
who would initially work with your technicians and show them the proper
techniques. This, however, would not be a substitute for the initial
training of your technician at the Blanik factory. The factory would
charge for the cost of the factory technician depending on your
interest and the duration of his stay at your facility, after a prior
agreement.
The cost of material needed for one glider.
Check with us for the latest update if seriously interested.
The number of manhours needed to modify one glider.
The
basic modification requires up to 200 manhours per glider. However, our
experience has been that often other service bulletins need to be
complied with in addition to the actual modification (if not yet done,
for
example, the bulletin L13/108a). Also, other needed repairs often need
to be done, which increases the overall amount of labor.
A timetable when the training at the factory could take place.
The earliest available date for training is from the beginning of September 2023.
To help you get an idea of what repair jigs would be needed, we can send you the document
< AMOC_1.1presentation.PDF> (Alternative Method of Compliance) which has been approved by the FAA.

There are over one hundred ninety L-13 Blaniks in North America!
The 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 L-13 Blanik is Type-Certified in most countries of the world.Wing span 53.1 ft

Wing area 206.1 sft
Max. weight 1100 lbs
Never exceed speed 136 kts
Rough air speed 76 kts
Aero tow speed max. 76 kts
Winch speed max. 65 kts
Stall speed at max. weight 32 kts
G-limits with 2 pilots +5.3/-2.65
G-limits with 1 pilot +6.0/-3.0
Max. glide ratio 2 pilots 28:1 at 49 kts, 1 pilot 28:1 at 43 kts
Min. rate of sink 160 fpm at 37 kts
Available equipment and accessories are: front aerotow and center of gravity winch hooks, 4-point seat belts, seat cushions, special seat back rests, extra seat with 33 lb ballast, one-piece canopy, cockpit cover, pitot cover, set of spare parts, flight manual, maintenance manual, spare parts catalogue, levelling and rigging record, weight and balance record.
Additional options are: White color all over with optional red stripes, winglets, wing installation drift pin, control locks and ground anchors, winch tow rope, wing tie-down rings, spart parts tool kit, strut charger, spare parts catalog. Also available as options are G-meter, 350' altimeter, radio and installation, special upholstery, center of gravity bottom winch tow hook, strut seal kit, covers for the entire glider, and custom paint ornamentation.FUSELAGE
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
FAA approved the modification to lift the grounding of L-13 Blaniks.
