SUBJECT:Airworthiness Directive 2004-26-09
SUMMARY:The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Corporation (RRC) 250-Band 250-C series turboprop and turboshaft engines with certain part numbers (P/Ns) ofcompressor adaptor couplings manufactured by Alcor Engine Company (Alcor), EXTEX Ltd.(EXTEX), RRC, and Superior Air Parts (SAP) installed. This AD requires operators to remove from service affected compressor adaptor couplings. This AD results from nine reports of engine shutdown caused by coupling failure. We are issuing this AD to reduce the risk of failure of the compressor adaptor coupling and subsequent loss of all engine power.
