Action
Final rule.
Summary
We are adopting a new airworthiness directive (AD) for all Airbus SAS Model A318 series; Model A319 series; Model A320 series; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. This AD was prompted by reports of multiple angle of attack (AoA) probe blockages. This AD requires all elevator aileron computer (ELAC) units to be upgraded with new software, or replaced with upgraded units. We are issuing this AD to address the unsafe condition on these products.
