## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain EMBRAER Model EMB-135 and -145 series airplanes. This proposal would require replacing the four Gamah clamp/sleeve joints on an engine bleed air duct with new threaded coupling assemblies. For certain airplanes, this proposal would also require replacing the two supports for the engine bleed air duct with two new supports. This action is necessary to prevent hot air leaks from the bleed air duct due to disconnection of the duct joint, which could result in heat damage to components near the duct, and consequent increased risk of fire in the rear baggage compartment. This action is intended to address the identified unsafe condition.
