What to do
Operators of Embraer EMB-500 and EMB-505 aircraft must, within 30 days of June 1, 2020, adopt the specified Embraer Operational Bulletins or use the approved AFM revisions when operating the aircraft. Compliance with either option constitutes full satisfaction of the AD requirements. Any alternative compliance methods require prior approval from ANAC's certification branch.
Summary
The Aircraft Flight Manual - Operational Envelope Temperature / Minimum Airspeed Limitation - Amendment is a Brazilian Airworthiness Directive (AD No. 2020-05-03) issued by ANAC that applies to Embraer EMB-500 and EMB-505 aircraft equipped with PW617F-E, PW617F1-E, or PW535E engines. It addresses operational limitations related to static air temperatures below -54°C to ensure safe aircraft operation within the approved flight envelope.
What changed
This AD introduces a requirement to adopt either specific Embraer Operational Bulletins or updated Aircraft Flight Manuals (AFM) revisions that limit the minimum airspeed in cold temperature conditions below -54°C. It mandates compliance within 30 days of the effective date and provides alternative methods of compliance subject to approval.
Why it matters
This directive is critical for aviation professionals as it prevents operation of affected Embraer aircraft in temperature conditions that could cause multiple system failures due to components operating outside their qualified temperature range. Operators, maintenance, and compliance teams must ensure the aircraft flight manuals or operational bulletins are updated to maintain flight safety and regulatory compliance.
