AD 2024-05-13 Airworthiness Directives; Embraer S.A. Airplanes
Models named: EMB-545, EMB-550. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to all Embraer S.A. Model EMB-545 and EMB-550 airplanes, 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, Agência Nacional de Aviação Civil (ANAC) AD 2024-02-02, effective February 26, 2024 (ANAC AD 2024-02-02). Note 1 to paragraph (g): Embraer EMB-545/EMB-550 Stall Protection, General Publication GP-8073, Revision 1, dated February 16, 2024, provides additional guidance regarding the actions required by this AD.
Unsafe condition
This AD was prompted by a report of a hard landing event with substantial damage to the airplane, in which the angle of attack (AOA) limiter was engaged during the final approach phase in unstable air conditions and remained engaged until the airplane touched down on the runway. The FAA is issuing this AD to address AOA limiter engagement during the final approach phase when the landing flare is commanded, which could reduce pitch response during a critical phase of flight near the ground. In unstable air conditions, this condition, if not addressed, could result in a high-rate-of-descent landing and consequent catastrophic structural damage to the airplane on landing.
Affected ADs
None.
