Airworthiness Directive · Amendment 39-16178 · Turbomeca Turmo IV A and IV C Turboshaft Engines
Turbomeca Turmo IV A and IV C Turboshaft Engines
This AD applies to Turbomeca Turmo IV A and IV C turboshaft engines that have incorporated Turbomeca Modification TU 233. These engines are installed on, but not limited to, Eurocopter SA 330F, G, or J PUMA helicopters.
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:
Unless already done, do the following actions.
(1) Before the next flight after the effective date of this AD, and thereafter daily after the last flight of the day until further notice, visually inspect for absence of oil leakage or seepage from both unions of the intermediate bearing return flexible pipes, part number 9 560 17 606 0.
(2) If any oil leakage or seepage is found, disassemble the pipe and visually inspect the unions.
(3) If no crack is found, re-install the pipe.
(4) If any crack is found, remove the pipe from service and replace it.
(5) The actions required by paragraph (e)(1) of this AD may be performed by the owner/operator holding at least a private pilot certificate, and must be entered into the aircraft records showing compliance with this AD in accordance with 14 CFR 43.9 and 91.417(a)(2)(v).
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.
