## Summary

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-200 and -300 series airplanes, and Model A340-200, - 300, -500, and -600 series airplanes. This proposed AD results from fuel system reviews conducted by the airplane manufacturer. This proposed AD would require removing bulb type maintenance lights; installing a drain mast on certain airplanes; and installing muffs on connecting bleed elements on certain airplanes. We are proposing this AD to prevent ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
