Airworthiness Directive 2023-11813
one-timeAirworthiness Directives; Embraer S.A. (Type Certificate Previously Held by Yaborã Indústria Aeronáutica S.A.; Embraer S.A.) Airplanes
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 190-300 and ERJ 190-400 airplanes. This AD was prompted by the excessive operation of certain elevator and rudder surfaces during manufacturing, causing damage and accelerating wear of internal parts of the power control units (PCUs). This AD requires replacement of the left-hand (LH) and right-hand (RH) elevator PCUs and lower and upper rudder PCUs, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2023-11813 applies to
As identified in Agencia Nacional de Aviacao Civil (ANAC) AD 2022-09-01, effective September 7, 2022.
Whether AD 2023-11813 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.
