Federal Aviation Administration April 24, 2019 – Federal Register Recent Federal Regulation Documents

We propose to supersede Airworthiness Directive (AD) 2015-17- 14, which applies to all Airbus SAS Model 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 2015- 17-14 requires repetitive rototest inspections of the open tack holes and rivet holes at the cargo floor support fittings of the fuselage, including doing all applicable related investigative actions, and repair if necessary. Since we issued AD 2015-17-14, further analysis and widespread fatigue damage (WFD) evaluations identified the need to reduce the initial compliance times and repetitive intervals for the inspections for certain airplanes, and to add work for certain airplanes. This proposed AD would continue to require the actions of AD 2015-17-14, would add actions for certain airplanes, and would reduce the compliance times for certain airplanes, as specified in an European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. This proposed AD would also reduce the applicability. We are proposing this AD to address the unsafe condition on these products.
