We are adopting a new airworthiness directive (AD) for various aircraft equipped with Rotax Aircraft Engines 912 A series engine. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a deviation in the manufacturing process of fuel hoses installed on the pressure side of part number 893114 fuel pumps. The fuel hoses may not be fuel resistant, which could lead to detachment of particles from the fuel hose and cause irregularities in the carburetor function and possibly result in rough engine operation, engine misfire, in-flight engine shutdown, and forced landing. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions in accordance with Rotax Aircraft Engines BRP Alert Service Bulletin ASB-912-061R1, dated May 31, 2012.
(1) Before further flight after August 14, 2012 (the effective date of this AD), replace the pressure side fuel hose on the P/N 893114 fuel pump.
(2) As of August 14, 2012 (the effective date of this AD), do not install a P/N 893114 fuel pump on any engine, unless the pressure side fuel hose of that fuel pump has been replaced as required in paragraph (f)(1) of this AD.
(3) As of August 14, 2012 (the effective date of this AD), do not install on any airplane a Rotax 912 A series engine, unless the fuel pump installation of that engine has been corrected as required in paragraph (f)(1) of this AD.
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.
