EASA SIB 2008-20: WITHDRAWN - FAA SAIB CE-08-12R1, CE-08-13 AND CE-08-14 NOW DIRECTLY ENDORSED

What to do

Affected operators should review the FAA SAIBs CE-08-12, CE-08-13, and CE-08-14 along with the associated service advisories from Cirrus Design Corporation, Piper Aircraft, and Garmin. They should monitor and address any transient voltage suppressor issues as recommended in those documents. For further information or clarification, stakeholders should contact the EASA Airworthiness Directives, Safety and Research Section via the provided email.

Summary

The document titled WITHDRAWN - FAA SAIB CE-08-12R1, CE-08-13 AND CE-08-14 NOW DIRECTLY ENDORSED is an EASA Safety Information Notice No. 2008-20 issued on 2008-03-07. It addresses an airworthiness concern related to the failure of transient voltage suppressors (TVS) in certain aircraft, as identified in FAA Special Airworthiness Information Bulletins CE-08-12, CE-08-13, and CE-08-14. The affected aircraft are those specified in the referenced FAA SAIBs, including models from Cirrus Design Corporation, Piper Aircraft, and Garmin equipment.

What changed

This notice formally endorses the FAA SAIBs CE-08-12, CE-08-13, and CE-08-14 directly, providing EASA recognition of the airworthiness concerns related to transient voltage suppressor failures. It consolidates information from multiple service advisories and bulletins from Cirrus Design Corporation, Piper Aircraft, and Garmin, emphasizing the potential pilot workload increase due to TVS failure.

Why it matters

This information is critical for aviation professionals because failure of transient voltage suppressors can increase pilot workload, potentially affecting flight safety. Operators, maintenance organizations, and compliance teams need to be aware of these issues to ensure continued airworthiness and operational safety of the affected aircraft. Recognizing the FAA SAIBs through EASA endorsement facilitates harmonized compliance and awareness across jurisdictions.
