What to do
Operators must amend the Airplane Flight Manual Section 2 - Limitations within 30 days after January 18, 2023, or install the updated Flight Control Computer software with Part Number 198-01000-258 as per Embraer Service Bulletin 190E2-27-0028. Compliance must be recorded in the maintenance logbook. Alternative compliance methods require approval from ANAC's Continuing Airworthiness Technical Branch.
Summary
The Brazilian Airworthiness Directive AD No. 2023-01-01R1 - EMBRAER / 39-1540 is an amendment issued by the Agência Nacional de Aviação Civil (ANAC) affecting Embraer S.A. airplanes models ERJ190-300 and ERJ 190-400. It addresses flight manual limitations related to stall warning system activation and angle of attack limiter engagement under certain gust conditions. This directive updates operational requirements to enhance flight safety for these aircraft.
What changed
This amendment cancels and supersedes the previous AD No. 2023-01-01 - EMBRAER / 39-1511 and introduces a new Flight Control Computer Operational Flight Program software update. The update eliminates the previously required Airplane Flight Manual limitations by correcting the flight control response to specific aerodynamic conditions. It also provides instructions for compliance through either AFM amendment or software installation.
Why it matters
This directive is critical for aviation professionals as it addresses a flight safety issue that could cause unexpected nose-up movements after stall warning activation, potentially affecting aircraft controllability. Operators and maintenance teams must ensure compliance to prevent safety risks and maintain airworthiness. The software update offers a terminating action that removes operational limitations, improving aircraft performance and reducing operational constraints.
