## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 190-100 ECJ airplanes. This proposed AD was prompted by a manufacturing quality escape concerning certain overheat detection system (ODS) sensing elements. This proposed AD would require a detailed inspection of certain ODS sensing elements of the airplane bleed lines and replacement, if necessary. This proposed AD would also prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
