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 following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Sarjapur Nagarajan, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4145; fax: (816) 329-4090; email: sarjapur.nagarajan@faa.gov . Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, a federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number. The OMB Control Number for this information collection is 2120-0056. Public reporting for this collection of information is estimated to be approximately 5 minutes per response, including the time for reviewing instructions, completing and reviewing the collection of information. All responses to this collection of information are mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at: 800 Independence Ave. SW., Washington, DC 20591, Attn: Information Collection Clearance Officer, AES-200.

This AD was prompted by 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 P/N 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. We are issuing this AD to prevent failure of the fuel hose on the pressure side of the P/N 893114 fuel pump, which could result in rough engine operation, engine misfire, in-flight engine shutdown, and forced landing.

None.
