Airworthiness Directives; Embraer S.A. Airplanes

AD 2026-10854 Published 2026-06-01 1 model 511 US-registered tails affected Federal Register ↗

Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. (Embraer) Model EMB-505 airplanes. This AD was prompted by the possibility that some airplanes may have invalid horizontal stabilizer (HS) backlash test results due to the use of incorrect procedures. This AD requires inspecting the airplane's left- hand (LH) and right-hand (RH) HS backlash and replacement, as applicable, of certain hinge point and pitch trim actuator attachment parts and the pitch trim actuator. The FAA is issuing this AD to address the unsafe condition on these products.
