Reason (d) European Aviation Safety Agency (EASA) AD No. 2006-0068, dated March 24, 2006, states: In operation, fuel leaks at the level of start electro valve fuel coupling were observed. A lack of power or an uncommanded in-flight shutdown may result from these fuel leaks. The condition described in the EASA AD may result in a forced autorotation landing, the inability to continue safe flight or a fire.

Within 90 days after the effective date of this AD, unless already done, do the following actions: (1) Check the condition of the three fuel unions and the ignition solenoid valve/start drain valve assembly, and check for their proper assembly. (2) Correct the installations if necessary. (3) Use Turbomeca Alert Service Bulletin No. A292 73 0251, Update No. 2, dated February 5, 2001, to do the checks and corrections. AD Differences (f) None.
