Airbus Model A330 and A340 Series Airplanes
Model A330-301 series airplanes, having manufacturer's serial numbers (MSN) 0030, 0037, 0045, 0054, 0055, 0059, and 0070, on which Airbus Modification 43222D40126 has not been installed; Model A340 -211, -212, -311, and -312 series airplanes, having MSN 0005 through 0009 inclusive, 0011, 0012 through 0016 inclusive, 0018 through 0029 inclusive, 0031 through 0033 inclusive, 0056 through 0058 inclusive, 0063, and 0074 through 0076 inclusive, on which Airbus Modification 43222D40126 has not been installed; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes. This action requires inspections to detect cracking, corrosion, and free play in the spherical washers located in certain assemblies where the aft flap track attaches to the wing trailing edge, and replacement of the washers, if necessary. This amendment is prompted by reports indicating that these washers can break under load. The actions specified in this AD are intended to prevent breakage of these washers, which could result in structural damage to the attachment assembly and eventually lead to separation of the flap from the airplane.
