Summary
We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Certain structural components must be replaced by new components at a certain stage of the aircraft's life to avoid any possibility of fatigue failure.
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
