Embraer EMB-135 and EMB-145 Aeroplanes - Mechanical Gust Lock System
Summary
EASA Safety Information Notice No. 2008-09 addresses the mechanical Gust Lock System on Embraer EMB-135 and EMB-145 aeroplanes. It clarifies that only certain EMB-145 models equipped with the pre-modification mechanical Gust Lock System are affected, specifically EMB-145EP, EMB-145ER, EMB-145LR, EMB-145LU, and EMB-145MP. The notice confirms that no EMB-135 aircraft are affected as they were delivered with an electromechanical gust lock system.
What Changed
This notice clarifies confusion caused by FAA Airworthiness Directive 2008-03-03 and Embraer Alert Service Bulletin 145-27-A106 regarding affected aircraft. It specifies that only 38 EMB-145 aircraft with the mechanical Gust Lock System pre-modification are subject to the safety concern, and that EMB-135 models are not technically applicable. It confirms that no new EASA AD action is required at this time.
Why It Matters
This clarification is important for operators, maintenance organizations, and compliance teams to correctly identify affected aircraft and avoid unnecessary modifications or inspections. It ensures that only the relevant EMB-145 models are addressed for compliance with the Gust Lock System safety issue. Understanding the correct applicability prevents confusion and supports regulatory compliance within the EU and internationally.
What To Do
Operators of EMB-145EP, EMB-145ER, EMB-145LR, EMB-145LU, and EMB-145MP aircraft should verify compliance with ANAC Airworthiness Directive 2002-01-01 R3 and Embraer Alert Service Bulletin 145-27-A106. No further action is required for EMB-135 aircraft. Stakeholders should maintain awareness of the applicable directives and contact EASA for further information if needed.
