Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to supersede Airworthiness Directive (AD) 2012-06- 19, for certain Airbus Model A330-201, -202, -203, -223, -243, -301, - 302, -303, -321, -322, -323, -341, -342, and -343 airplanes; and Model A340-200 and -300 series airplanes. AD 2012-06-19 currently requires repetitive inspections of the main fitting and sliding tube of the nose landing gear (NLG) for defects, damage, and cracks; and corrective actions if necessary. Since we issued AD 2012-06-19, we have determined that additional airplanes are affected by the identified unsafe condition. This proposed AD would add airplanes to the applicability. This proposed AD would require an inspection of the part number and serial number of the NLG main fitting and NLG sliding tube; for affected parts, a magnetic particle inspection (MPI) for cracks, and flap peening and replacement if necessary. This proposed AD would also require, for certain parts, additional inspections for damage and cracking. We are proposing this AD to detect and correct cracks, defects, or damage of the main fitting or sliding tube, which could result in consequent NLG collapse.
