AD NUMBER: 2011-24-05

MANUFACTURER: 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.
SUBJECT: Airworthiness Directive 2011-24-05
ACTION: Final rule

SUMMARY: The FAA is superseding an existing airworthiness directive (AD) that applies to 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. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product.

The MCAI describes the unsafe condition as:

During A330 and A340 aeroplanes fatigue tests, cracks appeared on the right (RH)
and left (LH) sides between the crossing area of the keel beam fitting and the front
spar of the Centre Wing Box (CWB). This condition, if not corrected, could lead to
keel beam rupture which would affect the area structural integrity.

DATES: This AD becomes effective January 3, 2012.
