## Summary

The FAA is revising an earlier proposed airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. The original NPRM would have required modifying the fuel boost pump container of the center tank. The original NPRM resulted from fuel system reviews conducted by the manufacturer. This action revises the original NPRM by adding airplanes to the applicability. We are proposing this supplemental NPRM to prevent exposing the fuel pump container vapor area to electrical arcing during a fuel pump motor case or connector burn through, which could result in a fuel tank explosion.
