2015-33173: Airworthiness Directives; Airbus Airplanes

Summary

We propose to supersede Airworthiness Directive (AD) 2011-17- 09 for all Airbus Model A330-200 series airplanes, -200 Freighter series airplanes, and -300 series airplanes, and AD 2012-25-12, for all Airbus Model A330-200 series airplanes and -300 series airplanes. AD 2011-17-09 currently requires revisions to certain operator maintenance documents to include new inspections. AD 2012-25-12 currently requires replacing certain main landing gear (MLG) bogie beams before reaching new reduced life limits. Since we issued AD 2011-17-09 and AD 2012-25- 12, we have determined that more restrictive instructions and/or airworthiness limitations should be incorporated into the maintenance or inspection program, as applicable. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or revised airworthiness limitation requirements. This AD results from revisions to the Airworthiness Limitations section (ALS) of the Instructions for Continued Airworthiness (ICA) to include new or more restrictive life limits and/or replacements. We are proposing this AD to detect and correct fatigue cracking, accidental damage, or corrosion in principal structural elements, and possible failure of certain life limited parts, which could result in reduced structural integrity of the airplane.
