Summary
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued 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:
* * * * *
* * * the FAA set-up in January 1999 an Ageing Transport Systems Rulemaking Advisory Committee (ATSRAC) to investigate the potential safety issues in aging aircraft as a result of wear and degradation in their operating systems.
Under this plan, all Holders of type Certificates aircraft are required to conduct a design review, to preclude the occurrence of potential unsafe conditions as the aircraft aged.
* * * * * The unsafe condition is degradation of the fuel system, which could result in loss of the airplane. The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
