CRACKS IN THE LOWER RUDDER HINGE
Applicable to the PIK 20, all variants, all serial numbers. Inspection of a PIK 20D revealed cracks in the bend zone of the lower rudder hinge attached to the fin post. It is suspected that flapping of the rudder in the wing whilst tied down may have been a contributing factor but also the fact that the subject fitting it appears that the bend was made along the 'grain' of the material. Heavy landings are known to contribute to this problem, which since 1980 has been found extensively overseas and in Australia.
