Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200 freighter series airplanes; Model A330- 200 and -300 series airplanes; and Model A340-200 and -300 series airplanes. This proposed AD was prompted by a report of corrosion found on the main fitting of the nose landing gear (NLG) leg in the vicinity of the dowel pin bushes retaining the lower steering flange. This proposed AD would require modifying the NLG main fitting by adding primer paint to the cadmium around the dowel bush holes. We are proposing this AD to prevent NLG main fitting rupture, which could result in an NLG collapse.
