We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
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.
None.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
