What to do

Operators of affected Embraer ERJ 170 and ERJ 190 series aircraft must perform initial and repetitive detailed or special detailed inspections of the engine pylon lower link lugs as specified by the directive. Any detected cracks require immediate reporting to ANAC and Embraer for repair approval before further flight. Compliance deadlines vary by aircraft model and flight cycles or hours, with termination actions available through maintenance program revisions incorporating specified Embraer MRB temporary revisions.

Summary

Brazilian Airworthiness Directive AD No. 2020-01-02R3 is a regulatory document issued by the Agência Nacional de Aviação Civil (ANAC) addressing inspection and repair requirements for engine inboard and outboard pylon lower link lugs on Embraer S.A. aircraft. The affected models include Embraer ERJ 170-100, ERJ 170-200, ERJ 190-100, ERJ 190-200, and ERJ 190-100 ECJ series airplanes. The directive mandates inspections, repairs, and modifications to prevent structural cracks that could compromise engine pylon integrity and aircraft safety.

What changed

This directive cancels and supersedes AD No. 2020-01-02R2 and introduces terminal actions to the previously required repetitive inspections. It expands the scope to include additional inspection thresholds, repair procedures, and maintenance program revisions for the specified Embraer aircraft models. The update also clarifies inspection intervals and defines detailed and special detailed inspection methods.

Why it matters

This directive is critical for aviation professionals because cracks in engine pylon lower link lugs can lead to engine separation, severely affecting aircraft controllability and safety. Operators and maintenance organizations must comply to ensure continued airworthiness and prevent potential accidents. The directive provides clear guidance on inspection intervals and repair approvals, facilitating regulatory compliance and risk mitigation.
