## Summary

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Model 382, 382B, 382E, 382F, and 382G airplanes. The existing AD currently requires revising the FAA- approved maintenance program by incorporating new airworthiness limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. That AD also requires the accomplishment of certain fuel system modifications, the initial inspections of certain repetitive fuel system limitations to phase in those inspections, and repair if necessary. This proposed AD would correct certain part number references, add an additional inspection area, and for certain airplanes, require certain actions to be re- accomplished according to revised service information. This proposed AD results from a report of incorrect accomplishment information in the service information cited by the existing AD. We are proposing 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 a fuel tank explosion and consequent loss of the airplane.
