Abstract
We are superseding Airworthiness Directive (AD) 2007-18-09 for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2007- 18-09 required repetitive inspections of the upper support of the nose landing gear (NLG), and related investigative and corrective actions if necessary; and also provided an optional terminating action for the repetitive inspections. This new AD adds installation of a new enhanced manufacturing and maintainability (EMM) braking and steering control unit (BSCU) standard, and adds airplanes to the applicability. This AD was prompted by a determination that previously allowed terminating actions no longer address the unsafe condition and that a new terminating action is necessary. We are issuing this AD to prevent landings with the NLG turned 90 degrees from centerline, which could result in reduced controllability of the airplane.
