Airworthiness Directive 2026-08-52
one-timeAirworthiness Directives; Embraer S.A. Airplanes
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for all Embraer S.A. Model EMB-545 and EMB-550 airplanes. The FAA previously sent this AD as an emergency AD to all known U.S. owners and operators of these airplanes. This AD was prompted by reports of in-service pitch trim actuator failures on one load path. This AD requires an operational check of the pitch trim actuator of the horizontal stabilizer, an option to do a pitch trim verification, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2026-08-52 applies to
Whether AD 2026-08-52 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
