FAA and ANAC Issue Emergency Airworthiness Directive for Embraer Business Jets

Date of publication : April 21, 2026

The Federal Aviation Administration (FAA) in the United States and Brazil’s National Civil Aviation Agency (ANAC) have jointly issued an Emergency Airworthiness Directive (AD) affecting a series of Embraer business jets.

The directive was triggered after safety concerns were identified regarding a critical flight control component, prompting immediate regulatory action to ensure continued airworthiness.

Aircraft Affected

The emergency directive applies to the following Embraer aircraft models:

• Embraer Legacy 450
• Embraer Legacy 500
• Embraer Praetor 500
• Embraer Praetor 600

These aircraft are widely operated in the global business aviation fleet. While exact fleet numbers under restriction vary by registry, these models collectively represent several hundred active aircraft worldwide, operated by private owners, charter companies, and corporate flight departments.

Identified Safety Concern

According to regulatory findings referenced in the FAA and ANAC emergency actions, the issue is linked to the:

• Pitch Trim Actuator (PTA) system
• Possible malfunction affecting stabilizer control authority

This condition could potentially lead to:

• Uncommanded pitch movement
• Reduced controllability of the aircraft
• Increased risk during critical flight phases such as climb or approach

The agencies classified the issue as an “unsafe condition” requiring immediate corrective action.

Regulatory Action Taken

Both the FAA and ANAC issued an Emergency Airworthiness Directive, which is one of the most urgent forms of aviation safety regulation.

Key regulatory measures include:

• Immediate inspection requirements for affected aircraft
• Mandatory compliance prior to further flight operations (in many cases)
• Operational restrictions until corrective actions are completed

Required Corrective Actions

Operators and maintenance organizations are instructed to:

1. Perform immediate inspections of the Pitch Trim Actuator system
2. Identify and replace affected components if necessary
3. Verify proper flight control system functionality before returning aircraft to service
4. Follow Embraer-issued maintenance and service bulletins referenced in the AD
5. Document compliance with FAA/ANAC requirements before resuming normal operations

What Operators Should Do Now

Until full compliance is achieved, operators are advised to:

• Ground affected aircraft if required by the specific AD applicability
• Consult their national aviation authority and Embraer service documentation
• Coordinate immediately with approved maintenance organizations
• Avoid dispatching aircraft with unresolved PTA inspection status
• Monitor for further FAA/ANAC updates or revisions to the directive

Conclusion

The joint FAA and ANAC emergency directive reflects a high-priority safety response affecting Embraer’s mid-size and super-midsize business jet fleet. While no accidents have been publicly confirmed in connection with the issue, regulators acted proactively due to the potential severity of a flight control malfunction.

Operators are expected to comply immediately with inspection and corrective procedures before returning affected aircraft to service.
