Abstract
We are adopting a new airworthiness directive (AD) for certain Airbus Model A340-211, -212, -311, and -312 airplanes. This AD requires repetitive inspections for cracking at the fastener hole area just above stringer 28, of both left- and right-hand fuselage frame 39.1, and repair if necessary. This AD was prompted by a determination that certain airplanes were not included in a certain airworthiness limitation item (ALI) task (inspections for cracking of the fuselage frame 39.1) and that the inspections must be done to address the identified unsafe condition. We are issuing this AD to detect and correct cracking in the fuselage that could result in reduced structural integrity of the airplane.
