2006-04-15 Turbomeca: Amendment 39-14497. Docket No. FAA-2006-23594; Directorate Identifier 2005-NE-54-AD. Effective Date (a) This airworthiness directive (AD) becomes effective March 14, 2006. Affected ADs (b) None. Applicability (c) This AD applies to Turbomeca Artouste III B, Artouste III B1, and Artouste III D turboshaft engines. These engines are installed on, but not limited to, Eurocopter France Alouette III SE.3160, SA.316B, SA.315B, and SA.316C helicopters. Unsafe Condition (d) This AD results from a report that an acceptance test facility used test equipment that was out of calibration, on certain fuel pumps, and those fuel pumps might have been accepted with a limitation in the maximum available fuel flow. We are issuing this AD to prevent reduced helicopter performance, subsequent loss of control of the helicopter, or accident. Compliance (e) You are responsible for having the actions required by this AD performed within 30 days or 80 operating hours after the receipt of a serviceable fuel pump, whichever occurs first, but no later than March 15, 2006, unless the actions have already been done. (f) Remove from service the fuel pumps listed by serial number (SN) in the following Table 1, and install a serviceable fuel pump.
