Summary
We propose to supersede Airworthiness Directive (AD) 2007-22- 10, for all Airbus Model A330-200, A330-300, A340-200, A340-300, A340- 500, and A340-600 series airplanes. AD 2007-22-10 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 cracking, and replacement if necessary. Since we issued AD 2007-22- 10, we have received reports of additional cracking of the MLG rib 6 aft bearing forward lug. This proposed AD would expand the applicability and 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.
