### TITLE: LANDING GEAR - MAIN GEAR - REPETITIVE INSPECTION OF THE INTERNAL SURFACE OF THE BOGIE BEAM **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES An operator of an A330 in-service aircraft reported that the bogie beam on the right hand MLG ruptured while taxiing during a slow turning manoeuvre. Investigations have revealed that the rupture was due to compromized paint protection leading to excessive corrosion on the internal surface of the bogie beam. Further investigations indicate that a corrosion pit reached a depth sufficient to promote stress corrosion cracking and a subsequent fast static rupture. No evidence of fatigue was apparent. Initial inspections of 15 aircraft on the bogie beams belonging to 5 operators have found 8 further bogie beams with compromized paint surfaces and corrosion in this area. A further 2 bogie beams were suffering from paint damage. So far no bogie beams have been scrapped but some repairs outside the published limits have been necessary. This Service Bulletin is published to advise operators of A340 aircraft of the issue of MESSIER DOWTY Service Bulletin No. A33/34-32-272. This Service Bulletin details instructions to perform a repeat inspection on the internal surface of the bogie beam assemblies to ensure that there is no corrosion. The inspection requires the removal of the bogie beam assembly and a detailed inspection of the internal surfaces using a boroscope. Accomplishment of this Service Bulletin will give an early detection of corrosion and prevent possible rupture of the bogie beam due to corrosion. This inspection requirement is cancelled by the accomplishment of Service Bulletin No. A340-32-4279. MESSIER-DOWTY Service Bulletin No. A33/34-32-284.
