Summary
We propose to adopt a new airworthiness directive (AD) for Embraer S.A. Model EMB-505 airplanes that would supersede AD 2013-22- 20. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracks beyond acceptable limits in the carbon discs of the left hand (LH) and right hand (RH) brake assemblies. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
