What to do
Operators of Embraer EMB-545 and EMB-550 airplanes must install the protective fairing covering the divan shroud and sideledge panel on both sides of the divan. This installation must be completed within 48 months after the original AD effective date of November 30, 2021, or within 48 months after the effective date of this revision for newly identified airplanes. Compliance must follow the procedures in Embraer Service Bulletin N. 550-25-0067, revision 02 or 03, as applicable, and be recorded in the maintenance logbook.
Summary
Brazilian Airworthiness Directive AD No. 2021-11-01R1 is an official regulatory document issued by the Agência Nacional de Aviação Civil (ANAC) that applies to Embraer S.A. model EMB-545 and EMB-550 airplanes. The directive mandates the installation of a protective fairing covering the divan shroud and sideledge panel to address a safety concern related to the shoulder belt retraction mechanism. This AD ensures continued airworthiness and safety compliance for affected aircraft registered in Brazil.
What changed
This AD revises and supersedes the previous AD No. 2021-11-01 / 39-1484 by expanding and clarifying the applicability to include additional Embraer EMB-545 and EMB-550 airplanes as identified in updated service bulletins. It introduces a requirement to install a protective fairing on both right-hand and left-hand sides of the divan shroud and sideledge panel to prevent interference with the shoulder belt retraction.
Why it matters
The directive addresses a critical safety issue where the shoulder belt could become stuck during flight due to interference caused by a step between the divan shroud chamfer and sideledge panel. For operators and maintenance teams, compliance is essential to ensure occupant safety during turbulence or emergency landings by maintaining proper shoulder belt functionality. Failure to comply could result in injury to occupants and regulatory non-compliance.
