What to do
Operators of Embraer EMB-505 aircraft with Garmin G3000 avionics must install the specified software updates within six months or 300 flight hours from the effective date of April 4, 2023, whichever occurs first. Compliance can be credited if previous updates were performed per earlier service bulletins. Alternative compliance methods require approval from ANAC's Continuing Airworthiness Technical Branch. Maintenance records must document the compliance.
Summary
Brazilian Airworthiness Directive AD No. 2023-04-01 is a regulatory document issued by the Agência Nacional de Aviação Civil (ANAC) that applies to Embraer EMB-505 aircraft equipped with the Garmin G3000 avionics system. The directive mandates a software update to address an issue with inadvertent barometric pressure setting changes affecting the altimeter readings on the Primary Flight Displays. This update is essential for maintaining safe flight operations and compliance with Brazilian aviation regulations.
What changed
AD No. 2023-04-01 introduces a requirement to install updated avionics software versions, specifically the G3000 Load 18.10, CMC Load 5.20, and Default Pilot Profile files, to correct the problem of unintended barometric pressure setting changes. This is a new directive rather than an amendment and does not cancel or revise any previous ADs. It also provides credit for compliance with earlier service bulletin revisions.
Why it matters
This directive is critical for aviation professionals because the erroneous altitude information caused by the software issue can lead to altitude mismanagement, spatial disorientation, and increased risk of loss of airplane control or controlled flight into terrain (CFIT). Operators and maintenance teams must ensure compliance to prevent potential safety hazards and maintain regulatory adherence. The update helps preserve flight safety and air traffic separation standards.
