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) 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:
Sponge rubber padding used to provide separation between wheel well fuel lines and electrical harnesses was discovered during fleet maintenance. Use of this type of padding for this purpose is not approved as it is liable to cause corrosion of the fuel lines. Unless steps are taken to remove this padding and install approved separation means, fuel lines may be damaged by corrosion and/or chafing resulting in an unsafe condition due to fuel leakage[, which could result in a fire] in the wheel well area.
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
