What to do
Operators must revise their maintenance programs within three months of the effective date to incorporate the updated airworthiness limitations from the MRB 1621 Revision 19 report. They must follow the specified inspection intervals and thresholds and seek approval for any alternative methods of compliance from ANAC if necessary. All compliance actions must be recorded in the maintenance logbooks.
Summary
Brazilian Airworthiness Directive AD No. 2023-12-01 issued by ANAC revises the maintenance program and airworthiness limitations for Embraer S.A. ERJ 170 series airplanes, including models ERJ 170-100 and ERJ 170-200 variants with specific manufacturer serial numbers. The directive mandates updates to maintenance and inspection programs to incorporate new or revised airworthiness limitations from the Embraer 170 and 175 Maintenance Review Board Report MRB 1621, Revision 19 dated July 14, 2023.
What changed
This directive cancels and supersedes four previous ADs related to Embraer 170 series airplanes and introduces updated airworthiness limitations including Certification Maintenance Requirements, Airworthiness Limitation Inspections, Fuel System Limitation Items, and Life Limited Items. It revises inspection tasks, thresholds, and intervals to enhance detection of fatigue cracking and ensure structural integrity. The directive also sets new compliance requirements based on the latest MRB report revision.
Why it matters
The updated airworthiness limitations are critical for operators and maintenance organizations to prevent structural failures due to fatigue cracking by ensuring timely inspections and maintenance. Compliance with these requirements is mandatory under Brazilian civil aviation regulations and directly impacts flight safety and continued airworthiness. Failure to comply could lead to unsafe conditions and regulatory penalties.
