### TITLE: LANDING GEAR - MLG - REPEAT INSPECTION OF MLG BOGIE PIVOT PIN **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES The bogie pivot pin makes the connection between the landing gear slider and the bogie beam. This component is a Principal Structural Element (PSE). In-service feed-backs indicate an increasing number of bogie pivot pin replacements due to unexpected findings upon removal. Operators report a high number of events related to chrome detachment or chrome dragging. There have been a number of confirmed crackings of the bogie pivot pins since Entry Into Service (EIS). This Service Bulletin is published to advise all operators of A340 aircraft of the issue of Messier-Dowty Service Bulletin No. A33/34-32-285. VSB A33/34-32-285 details: - Detailed Visual Inspections (DVI) of the bogie pivot pin chromium-plated surface- Magnetic Particle Inspections (MPI) of the bogie pivot pin if damage is found to the chromiumplated surface - DVI’s of the pivot pin bushes in the bogie beam and sliding tube. These inspections will: - make sure that all damaged bogie pivot pins are repaired or replaced if found damaged - gather detailed information from the fleet to further investigate this issue.
