Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Model A310 airplanes and Model A300-600 series airplanes. This proposed AD would require revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness by incorporating new and revised certification maintenance requirements. This proposed AD results from the manufacturer determining that additional and revised certification maintenance requirements are necessary in order to ensure continued operational safety of the affected airplanes. We are proposing this AD to prevent safety- significant latent failures that would, in combination with one or more other specific failures or events, result in a hazardous or catastrophic failure condition of avionics, hydraulic systems, fire detection systems, fuel systems, or other critical systems.
