What to do
Operators of Embraer ERJ-190-300 and ERJ-190-400 airplanes must revise their maintenance or inspection programs within three months of the AD's effective date to incorporate the updated airworthiness limitations from MRB-5881 Revision 06 or later approved revisions. Any alternative inspection methods or intervals require prior approval from ANAC's Continuing Airworthiness Technical Branch. Compliance must be recorded in the maintenance logbook.
Summary
Brazilian Airworthiness Directive AD No. 2025-07-02 is a regulatory document issued by the Agência Nacional de Aviação Civil (ANAC) that applies to Embraer S.A. ERJ-190-300 and ERJ-190-400 airplane models. It mandates revisions to the maintenance or inspection programs to incorporate updated airworthiness limitations, including Certification Maintenance Requirements, Airworthiness Limitation Inspections, Fuel System Limitation Items, and Life Limited Items.
What changed
This directive introduces a revision to the Maintenance Review Board Report MRB-5881, Revision 06, dated March 28, 2025, requiring operators to update their maintenance programs with new or modified inspections, thresholds, and intervals. It establishes mandatory compliance with these updated airworthiness limitations to ensure timely detection of fatigue cracking and maintain structural integrity.
Why it matters
Compliance with AD No. 2025-07-02 is critical for operators and maintenance organizations to prevent structural failures caused by undetected fatigue cracks. The directive ensures continued airworthiness by enforcing mandatory inspections and maintenance tasks that directly impact flight safety. Failure to comply could result in unsafe conditions and regulatory penalties.
