## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 727-281 airplanes. This proposed AD would require deactivation of Rogerson Aircraft Corporation auxiliary fuel tanks. This proposed AD results from fuel system reviews conducted by the manufacturer, which identified potential unsafe conditions but has not provided associated corrective actions. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
