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:
A few hydraulic system tube clamps located inside the wing fuel tanks were found damaged. Further analysis has shown that damage to multiple clamps may cause sparks inside the tanks, which in turn may lead to ignition of flammable vapors inside the fuel tanks.
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
