What to do
Operators of EC135, EC635, and MBB-BK 117C-2 helicopters should follow the inspection, repair, or replacement instructions outlined in the referenced Luftfahrt-Bundesamt Germany Airworthiness Directives and Eurocopter Alert Service Bulletins. They should also refer to EASA Airworthiness Directive 2010-0058 for the current mandatory requirements. Contact EASA Airworthiness Directives, Safety Management & Research Section for further information if needed.
Summary
EASA Safety Information Bulletin 2008-45 is an informational bulletin addressing incorrect fixed bearings in the main rotor and tail rotor flight control levers of EC135, EC635, and MBB-BK 117C-2 helicopters. The bulletin highlights inspection, repair, and replacement requirements as per Luftfahrt-Bundesamt Germany Airworthiness Directives and Eurocopter Deutschland GmbH Alert Service Bulletins. This bulletin is withdrawn and superseded by EASA Airworthiness Directive 2010-0058.
What changed
EASA SIB 2008-45 informs operators about a safety issue related to manufacturing non-conformity affecting fixed bearings in rotor control levers but clarifies that EASA does not issue mandatory ADs for this issue as it is not related to design approval. Instead, national aviation authorities may enforce the referenced German Airworthiness Directives. The bulletin has been withdrawn and replaced by EASA AD 2010-0058.
Why it matters
This bulletin matters because it alerts operators and maintenance organizations to a serious safety concern involving rotor control lever bearings that could affect flight safety. Although not mandatory under EASA jurisdiction, compliance with national directives is critical to ensure safe operation and avoid potential failures. Understanding the regulatory scope helps compliance teams manage their responsibilities effectively.
