Airworthiness Directives; Airbus Model A300 B2-203 and B4-203 Airplanes; Model A310-200 and -300 Series Airplanes; and Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model A300 C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes)

Riepilogo

The FAA is adopting a new airworthiness directive (AD) for certain Airbus transport category airplanes. This AD requires an inspection to determine if suspect part numbers (P/Ns) and serial numbers of certain Thales Avionics equipment are installed, and replacement of any suspect part with a modified part having a new P/N. This AD is prompted by reports of loss of the digital distance radio magnetic indicator and subsequent loss of both very high frequency omnidirectional range indicators, both distance measuring equipment, and one centralized maintenance computer. We are issuing this AD to prevent loss of navigation indications on the primary flight display requiring continuation of the flight on emergency instruments, which could lead to reduced ability to control the airplane in adverse conditions.
