## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain transport category airplanes identified above. This AD requires modifying the fuel boost pumps. This AD results from a fuel boost pump found with blown thermal fuses and a fractured thrust washer. We are issuing this AD to prevent failure of the fuel boost pumps, which could lead to the potential of ignition sources inside fuel tanks. This condition, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
