Summary
We propose to supersede Airworthiness Directive (AD) 2014-26- 10, for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2014-26-10 currently requires revising the maintenance or inspection program to incorporate maintenance requirements and airworthiness limitations. Since we issued AD 2014-26-10, we have determined that more restrictive maintenance instructions and airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or revised airworthiness limitation requirements. This proposed AD also removes airplanes from the applicability. We are proposing this AD to address the unsafe condition on these products.
