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

**Buyer:** Federal Aviation Administration (FAA), U.S. Department of Transportation
**Posted:** October 01, 2026
**Respond By:** November 16, 2026
**Identifier:** FAA-2026-11796

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.
