This new AD requires, for certain airplanes, additional inspections for cracking of the tension tie at body station (BS) 760 or 780, corrective action if necessary, and eventual modification of the tension ties. For all airplanes, this new AD requires repetitive post- modification inspections for cracking of the tension tie at BS 760 or 780, and corrective action if necessary. This AD was prompted by reports of cracking in the BS 760 tension tie as a result of bending due to cabin pressurization. We are issuing this AD to detect and correct tension tie cracking, which could eventually result in in- flight depressurization of the airplane and the inability to withstand current regulatory failsafe loads.

We are superseding Airworthiness Directive (AD) 2008-08-04 for certain Airbus Model A318, A319, A320, and A321 series airplanes. AD 2008-08-04 required repetitive inspections for cracking in the forward lug of the support rib 5 fitting of the left and right main landing gear (MLG), and repair or replacement of any cracked MLG fitting if necessary. AD 2008-08-04 also required modification of the rib bushings of the left and right MLG, which ended the repetitive inspections. This new AD requires, for airplanes on which certain modifications or repairs have been done, repetitive inspections for cracks of the forward lug of each left-hand and right-hand MLG support rib 5 fitting, and repair if necessary; and adds Model A318 series airplanes to the applicability. Replacement of an MLG support rib 5 fitting terminates the repetitive inspection requirements for the MLG support rib 5 fitting at that position. This AD was prompted by reports of cracks found in the forward lug of the MLG support rib 5 fitting. We are issuing this AD to prevent cracking in the forward lug of the MLG, which could result in failure of the lug and consequent collapse of the MLG during takeoff or landing.
