AD 2023-21-04 Airworthiness Directives; Embraer S.A. Airplanes
Models named: EMB-505. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Embraer S.A. Model EMB-505 airplanes, as identified in paragraph (a) of Agência Nacional de Aviação Civil (ANAC) AD 2023-04-01, effective April 4, 2023 (ANAC AD 2023-04-01), certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, ANAC AD 2023-04-01.
Unsafe condition
This AD was prompted by occurrences of an uncommanded change in the setting of the barometric pressure in both primary flight displays (PFDs). The FAA is issuing this AD to address the uncommanded change in the setting of the barometric pressure in both PFDs. The unsafe condition, if not addressed, could result in altitude mismanagement or spatial disorientation of the flight crew, with consequent deviation from the intended altitude and loss of control of the airplane, risk of air collision due to inadequate air traffic separation, or risk of controlled flight into terrain.
Affected ADs
None.
