AD 2026-10854

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.

Applicability · by US fleet size

• EMBRAER EXECUTIVE EMB-505 TCDS A60CE 526 tails
