What to do
Operators must inspect, replace, and re-torque the left-hand and right-hand pylon lower link fitting attaching parts according to the specified Embraer Service Bulletins and within the compliance times outlined. Detailed inspections of external shear pins must be performed, with replacements as necessary, and modifications applied to the attaching parts. Compliance must be achieved by the effective date or within the specified flight cycles or hours as detailed in the directive.
Summary
Brazilian Airworthiness Directive AD No. 2020-06-02R02 issued by Agência Nacional de Aviação Civil (ANAC) addresses inspection, replacement, re-torque, and modification of pylon lower link fitting inboard and outboard attaching parts on Yaborã Indústria Aeronáutica S.A. airplanes, specifically various models of the Embraer ERJ 190 series. The directive applies to aircraft registered in Brazil and mandates compliance to ensure continued airworthiness and safety.
What changed
This revision changes the compliance times for re-torque and inspection tasks on Group 3 aircraft as identified in Embraer Service Bulletins 190-54-0015 and 190LIN-54-0006. It also updates contact information for approval of alternative methods of compliance and supersedes previous AD revisions to include additional service bulletin revisions approved by ANAC.
Why it matters
The directive addresses critical safety concerns related to cracked nuts and damaged external shear pins on the pylon lower link fittings, which if not corrected, could lead to engine separation from the wing. For operators and maintenance organizations, adhering to these requirements is essential to prevent potential catastrophic failures and ensure regulatory compliance with Brazilian aviation safety standards.
