Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for all Airbus Defense and Space S.A. Model CN-235, CN 235-100, CN 235-200, and CN 235-300 airplanes, and Model C-295 airplanes. This proposed AD was prompted by leakage of a motorized cross-feed fuel valve. This proposed AD would require an inspection of the affected fuel valves and, depending on findings, applicable corrective action(s). We are proposing this AD to detect and correct leaks in a motorized cross-feed fuel valve, which could lead to failure of the fuel valve and consequent improper fuel system functioning or, in case of the presence of an ignition source, an airplane fire.
