Airworthiness Directives; Airbus Airplanes

We propose to supersede Airworthiness Directive (AD) 2015-03- 06, for all Airbus Model A330-200, A330-200 Freighter, A330-300, A340- 200, A340-300, A340-500, and A340-600 series airplanes. AD 2015-03-06 currently requires repetitive inspections of the left-hand and right- hand wing main landing gear (MLG) rib 6 aft bearing lugs (forward and aft) to detect any cracks on the two lugs, and replacement if necessary. Since we issued AD 2015-03-06, we have received reports of additional cracking of the MLG rib 6 aft bearing lugs. This proposed AD would reduce certain compliance times. We are proposing this AD to detect and correct cracking of the MLG rib 6 aft bearing lugs, which could result in collapse of the MLG upon landing.
