RUDDER LOWER ATTACHMENT INSPECTION / REPLACEMENT OF SECURING NUT
During flight the rudder became disconnected on the SZD-50-3. It was thought that this was the result of an incorrect nut having been fitted to the bottom bolt. In 1981, PZL Bielsco BK-06/50-3/81 was issued requiring the use of a castellated nut and cotter pin to secure this bolt in lieu of a self-locking nut but due to oversight the change was not applied to the Technical Service Manual. The EASA has issued AD 2006-0243-E, and Allstar PZL has issued Mandatory Bulletin BE-058/SZD-50-3/2006 which forms part of this AD.
