We are adopting a new airworthiness directive (AD) for the products listed above that will supersede an existing AD. 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:
Unless already done, do the following actions:
(1) Replace washer, part number (P/N) 944072, and associated gasket ring, P/N 950141, on the magneto ring flywheel hub with FAA-approved serviceable parts with the same P/Ns. Do the replacements following the Accomplishment Instructions in Rotax Aircraft Engines Mandatory Service Bulletin SB-912-058 and SB-914-041 (same document), dated April 15, 2011.
(i) For Group 1 airplanes (airplanes previously affected by AD 2011-11-03): Within the next 10 hours time-in-service (TIS) after June 16, 2011 (the effective date retained from AD 2011-11-03) or within 4 months after June 16, 2011 (the effective date retained from AD 2011-11-03), whichever occurs first.
(ii) For Group 2 airplanes (airplanes not previously affected by AD 2011-11-03): Within the next 10 hours TIS after July 25, 2011 (the effective date of this AD) or within 4 months after July 25, 2011 (the effective date of this AD), whichever occurs first.
(2) Do not install a Rotax Aircraft Engines 912 A series engine listed in paragraph (c) of this AD unless the washer, P/N 944072, and the gasket ring, P/N 950141, have been replaced as required in paragraph (f)(1) of this AD.
(i) For Group 1 airplanes (airplanes previously affected by AD 2011-11-03): As of June 16, 2011 (the effective date retained from AD 2011-11-03).
(ii) For Group 2 airplanes (airplanes not previously affected by AD 2011-11-03): As of July 25, 2011 (the effective date of this AD).
Note: This AD differs from the MCAI and/or service information as follows: EASA AD 2011-0067-E, dated April 15, 2011, requires returning the removed P/N 944072 to Rotax Aircraft Engines. We are not requiring this because FAA regulation, specifically 14 CFR 43.10, already requires disposition of unairworthy parts.
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.
