Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-88 airplanes. This proposed AD would require installing a clamp, a bonding jumper assembly, and attaching hardware to the refueling manifold in the right wing refueling station area. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to prevent arcing on the in-tank side of the fueling valve during a lightning strike, which could result in an ignition source that could ignite fuel vapor and cause a fuel tank explosion.
