## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model ERJ 170 and ERJ 190 airplanes. This proposed AD would require repetitive inspections to detect damaged smoke seals in the aft avionics compartment, repair/replacement if any damage is found, and reinforcement if no damage is found. This proposed AD also would require eventual replacement of all smoke seals in the aft avionics compartment with new, improved seals having new part numbers, which would terminate the repetitive inspections. This proposed AD results from a report of damaged smoke seals in the aft avionics compartment of the affected airplanes. We are proposing this AD to prevent smoke from penetrating into the passenger cabin during a fire in the avionics compartment.
