[Correction] Airworthiness Limitations (Certification Maintenance Requirements, Airworthiness Limitation Inspections, Fuel System Limitation Items, and Life Limited Items) - Revision
Summary
Brazilian Airworthiness Directive AD No. 2025-09-02 is a regulatory document issued by the Agência Nacional de Aviação Civil (ANAC) applicable to all Embraer S.A. model EMB-135BJ aircraft, covering all serial numbers. This directive mandates revisions to operator maintenance programs to incorporate updated airworthiness limitations including Certification Maintenance Requirements, Airworthiness Limitation Inspections, Fuel System Limitation Items, and Life Limited Items. It ensures continued airworthiness and structural integrity by enforcing compliance with updated inspection thresholds and intervals.
What Changed
AD No. 2025-09-02 introduces new and revised airworthiness limitations based on the Maintenance Review Board Report, requiring operators to update their maintenance or inspection programs accordingly. The directive corrects previous errors in paragraph references and effective dates through issued errata, clarifying compliance procedures and timelines. It also establishes that alternative inspection methods or intervals require prior approval from ANAC's Continuing Airworthiness Technical Branch.
Why It Matters
This directive is critical for aviation professionals as it ensures timely detection of fatigue cracking and other structural issues that could compromise aircraft safety. Operators and maintenance organizations must adhere to these updated limitations to maintain regulatory compliance and avoid unsafe conditions. The directive also provides a clear process for requesting alternative compliance methods, supporting operational flexibility while maintaining safety standards.
What To Do
Operators of Embraer EMB-135BJ aircraft must revise their maintenance or inspection programs within three months of the effective date, incorporating the specified airworthiness limitations from the Legacy 600/650 Maintenance Planning Guide, MPG-1483 Revision 15 or later ANAC-approved revisions. Any alternative inspection procedures or intervals require ANAC approval as an alternative method of compliance. Compliance must be recorded in the maintenance logbook, and operators should refer to the errata for corrected procedural references.
