FAA SAIB NE-07-42R1 - Kelly Aerospace Power Systems Turbochargers and related control components
Summary
FAA Special Airworthiness Information Bulletin (SAIB) NE-07-42R1 addresses potential discrepancies in turbochargers and related control components overhauled by Statesville AeroTech Services between January 2005 and June 22, 2007. Affected aircraft include various models from Beechcraft, Cessna, Columbia, Commander, Lancair, Mooney, and Piper equipped with turbocharged engines. The bulletin highlights concerns about incomplete overhaul processes that may impact engine performance and component reliability.
What Changed
This SAIB introduces an alert regarding turbochargers and control components that may have been returned to service with incomplete or inappropriate overhaul procedures by Statesville AeroTech Services. It provides a partial list of affected components and recommends inspection and functional testing during the next 100-hour or annual inspection. The bulletin does not mandate actions but advises operators to verify component airworthiness and replace parts if necessary.
Why It Matters
This information is critical for aviation professionals because the affected turbochargers and control components may cause operational issues such as unstable turbocharger operation, high oil consumption, and failure to achieve rated engine performance. Operators, maintenance organizations, and compliance teams need to be aware of these potential discrepancies to ensure continued airworthiness and safety of affected aircraft. Early detection and corrective action can prevent possible engine performance degradation or component failure.
What To Do
Owners and operators should inspect turbochargers and related control components overhauled by Statesville AeroTech Services during the specified period at the next 100-hour or annual inspection. Functional testing should be conducted following engine or aircraft maintenance manuals or Kelly Aerospace Power Systems Service Bulletin No. 23. If any doubts about component airworthiness arise, replacement with serviceable parts is recommended.
