Summary
We propose to supersede Airworthiness Directive (AD) 2016-19- 14, which applies to certain Airbus SAS Model A318 and A319 series airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2016-19-14 requires repetitive inspections for cracking of the 10VU rack fitting lugs, and repair of any cracking. Since we issued AD 2016-19-14, we have determined that the unsafe condition may exist on additional airplanes. This proposed AD continues to require repetitive inspections for cracking of the 10VU rack fitting lugs, and repair of any cracking. This proposed AD would also add airplanes to the applicability. We are proposing this AD to address the unsafe condition on these products.
