## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This AD requires installing in-line fuel float switch fuses and wire protection at the left, right, and center forward spars. This AD results from a design review of the fuel tank systems conducted by the manufacturer. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
