## Summary

The FAA proposes to supersede an existing airworthiness directive (AD) for all EMBRAER Model EMB-135 and -145 series airplanes. That AD currently requires repetitive inspections of the electrical connectors of the electric fuel pumps to detect discrepancies, and follow-on corrective actions. This proposed AD would extend the repetitive intervals for the inspections; add new criteria for replacing discrepant fuel pumps; add a new requirement for applying anti-corrosion spray; add a requirement to replace all fuel pumps with improved fuel pumps; and add repetitive inspections after all six fuel pumps are replaced. This proposed AD is prompted by the manufacturer's development of a new modification that addresses the unsafe condition in the existing AD. We are proposing this AD to prevent an ignition source in the fuel tank or adjacent dry bay, which could result in fire or explosion.
