Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Model A330 and A340 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 (CMRs). This proposed AD results from the manufacturer's determination that additional and revised CMRs 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.
