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.
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.
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.
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.
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.
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.
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.
