EASA AD BR-2022-12-01
Time Limits / Maintenance Checks — Time Limits Manual / Maintenance Programme — Amendment
Summary
Brazilian Airworthiness Directive AD No. 2022-12-01 issued by the Agência Nacional de Aviação Civil (ANAC) mandates revisions to the maintenance programs of Embraer S.A. ERJ 190-100 and ERJ 190-200 series airplanes. This directive requires incorporation of new Airworthiness Limitation Inspections and structural modifications to address Widespread Fatigue Damage risks. It applies to specific serial numbers and all aircraft registered in Brazil under the Registro Aeronáutico Brasileiro.
What Changed
AD No. 2022-12-01 introduces updated maintenance requirements based on Revision 14 of the Embraer 190/195 Maintenance Review Board Report, including new inspection thresholds and intervals. It mandates structural modifications before reaching defined Structural Modification Points to prevent fatigue damage. The directive also establishes alternative methods of compliance procedures and terminates previous repetitive inspections required by ANAC AD 2019-06-01 upon modification completion.
Why It Matters
This directive is critical for operators and maintenance organizations to ensure continued airworthiness and structural integrity of Embraer ERJ 190 aircraft. Compliance prevents potential widespread fatigue damage that could compromise flight safety. It also ensures regulatory adherence to Brazilian aviation law and RBAC requirements, avoiding operational restrictions or penalties.
What To Do
Operators must revise their maintenance or inspection programs within 30 days of the directive's effective date to include the new Airworthiness Limitation Inspections. Structural modifications must be incorporated before reaching specified flight cycle or flight hour limits as detailed in the directive. For airplanes exceeding these limits at the effective date, modifications must be completed within 3,000 flight cycles or 4,000 flight hours, whichever occurs first. Requests for alternative compliance methods must be approved by ANAC's Continuing Airworthiness Technical Branch.
