EASA AD BR-2023-08-03R2
Windows - Cockpit Side Windows - Inspection / Replacement
Summary
Brazilian Airworthiness Directive AD No. 2023-08-03R02 is an official regulatory document issued by the Agência Nacional de Aviação Civil (ANAC) that applies to Embraer S.A. airplanes model EMB-545 and EMB-550 equipped with cockpit side windows having Part Numbers NP-200402-7 or NP-200402-8. The directive mandates inspection and replacement procedures for these cockpit side windows to address safety concerns. It provides detailed inspection methods and replacement requirements to prevent potential in-flight depressurization due to window failure.
What Changed
This AD revises and supersedes the previous AD No. 2023-08-03R01 by clarifying corrective actions related to damages other than cracks found on the affected cockpit side windows. It emphasizes inspection for delamination, scratches, erosion, or other damages and specifies replacement with new part numbers if cracks are detected. The updated directive also prohibits installation of the older window part numbers after its effective date.
Why It Matters
This directive is critical for aviation professionals because it addresses a safety risk involving premature cracks in cockpit side windows that could lead to in-flight depressurization. Operators and maintenance organizations must ensure timely inspections and replacements to maintain aircraft airworthiness and passenger safety. Compliance with this AD helps prevent unexpected window failures and supports regulatory adherence for aircraft registered in Brazil.
What To Do
Operators of Embraer EMB-545 and EMB-550 aircraft with the specified cockpit side windows must perform initial and repetitive general visual inspections before the windows reach 2,000 flight cycles or within 1,200 flight cycles after November 2, 2023, whichever is later. If cracks are found, the windows must be replaced before the next flight with approved new part numbers. Installation of the older window parts is prohibited after the AD's effective date. All inspections and replacements must follow the specified Aircraft Maintenance Manual task.
