Allstar has received the fields report as during the flight, while retracting from the spin, after 

applying of front left rudder pedal, the fitting block of the rudder cable to the floor went out. 

The reason could be improper gluing of the block including the fitting screw to the fulesage shell 

or partial cracking of gluing of fuselage 's shell to the stiff block. 

This SB describes the actions to be taken to reduce occurence of the fault as above in future. 

2. GLIDERS AFFECTED 

All SZD-50-3 , Puchacz" as well as SZD-50-1M (SIN X-127) & SZD-50-2 (SIN) X-129, in case 

of not fulfilling the actions as described in item 3 as below.

3 .1. Inspections 

Immediately after receiving of this SB inspect the painting area around the block, in the place 

of fitting of the rudder cables and gluing to the fuselage's shell, close to the pedals: left and

In case of crack's found in any places (left or right fitting), before the next flight, correct the 

fitting ofboth blocks to the shell. Follow ace. to the description in item 3.2 of the SB. 

In cracks do not appear, the glider may be exploitated until the repair ace. to item 3.2 is to be 

performed.

In the period of time up to 12 months from receiving of this SB, for ex. during the nearest 

annual inspection, the repair as below should be carried out, independently if the crack is 

found or not (as per attached Fig. 1). 

Both blocks should be laminated into the fuselage's shell with angle fabric of 20 mm width, 

based on two layers of 92110 INTERGLAS chamfer fabric (see Fig. 2) and following the
