Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes. This proposed AD was prompted by a report that revealed the wheel axles of the main landing gear (MLG) were machined with a radius as small as 0.4 millimeters and a determination that the life limit for the affected wheel axles of the MLG must be reduced. This proposed AD would require an inspection to determine the part number and serial number of each MLG wheel axle and replacement of affected parts prior to exceeding the reduced life limits. We are proposing this AD to address the unsafe condition on these products.
