Federal Register #FAA-2026-11796

FAA proposes FCC software and flight-manual updates for Embraer EMB-545 and EMB-550 airplanes

The FAA is proposing an airworthiness directive for Embraer EMB-545 and EMB-550 airplanes to address a flight-control safety risk. - Government: U.S. Department of Transportation, Federal Aviation Administration (FAA), Operational Safety Branch. - OEM: Embraer S.A., manufacturer of the affected airplane models. Agencia Nacional de Aviação Civil (ANAC) is cited as the source of compliance material. - Affected aircraft: All Embraer Model EMB-545 and EMB-550 airplanes. - Required update: Update flight control computer (FCC) software to part number 494910-1011 and reidentify FCC 1 and FCC 2, as specified in the referenced ANAC directive. Quantity is not specified. - Related requirement: Revise the airplane flight manual (AFM). The software update would end specified airspeed and flight-control limitations and approach procedures related to angle-of-attack limiter protection. - Safety rationale: The action addresses the risk of reduced pitch response during final approach, which could result in a high-rate-of-descent landing and catastrophic structural damage. - This is a proposed regulatory action, not a procurement solicitation or contract award; no purchase quantities or contract value are provided.

Description

The FAA proposes to supersede Airworthiness Directive 2024-05-13 for all Embraer S.A. Model EMB-545 and EMB-550 airplanes. The proposal would retain certain existing requirements and require updating flight control computer software and incorporating a revised airplane flight manual. These updates would end specified airspeed and flight-control limitations and approach procedures associated with angle-of-attack limiter protection. The proposed directive addresses the risk of reduced pitch response during final approach, which could lead to a high-rate-of-descent landing and catastrophic structural damage.
