AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed tlemaking (NPRM).

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products

listed above. This proposed AD ~esults from mandatory continuing airworthiness

information (MeAl) originated by an aviation authority of another country to identify

and correct an unsafe condition bn an aviation product. The MeAl describes the unsaf,

condition as:

Sponge rubber padding used to provide separation between wheel well

fuel lines and electrical harnesses was discovered during fleet

maintenance. Use ofthd type of padding for this purpose is not approved

as it is liable to cause cohosion of the fuel lines. Unless steps are taken to

remove this padding an~ install approved separation means, fuel lines may

be damaged by corrosion and/or chafIng resulting in an unsafe condition

due to fuelleakage[,whith could result in a fire] in the wheel well area.

The proposed AD would reqUiJ actions that are intended to address the unsafe condition

described in the MeAl.
