BRP-Powertrain GmbH & Co. KG Rotax 912 F3, 912 S2, 912 S3, 912 S4, 914 F2, 914 F3, and 914 F4 Reciprocating Engines
This AD applies to the following BRP-Powertrain GmbH & Co. KG Rotax reciprocating engines:
(1) Model 912 F3—serial number (S/N) 4,412.986 and S/N 4,412.987.
(2) Models 912 S2, 912 S3, and 912 S4—S/N 4,924.087 through S/N 4,924.139 inclusive, and S/N 4,924.141 through 4,924.166 inclusive.
(3) Models 914 F2, 914 F3, and 914 F4—S/N 4,420.970 through 4,420.990 inclusive, S/N 4,420.997, and S/N 4,421.001 through 4,421.003 inclusive.
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 within 10 flight hours or at next maintenance after the effective date of this AD, whichever occurs first:
(1) Replace the magneto ring flywheel hub washer, P/N 944072.
(2) Use paragraph 3.1 of BRP-Powertrain GmbH & Co. KG Rotax Mandatory Service Bulletin SB-912-058, dated April 15, 2011 or SB-914-041 dated April 15, 2011, to do the replacement.
After the effective date of this AD, do not install any washer P/N 944072 removed as specified in paragraph (e)(1) of this AD into any magneto or onto any engine.
This AD differs from the Mandatory Continuing Airworthiness Information (MCAI) as follows:
(1) European Aviation Safety Agency (EASA) AD 2011-0067-E requires compliance within 10 flight hours or 4 calendar months after the effective date of the AD, whichever occurs first. This AD requires compliance within 10 flight hours or at next maintenance after the effective date of this AD, whichever occurs first.
(2) EASA AD 2011-0067-E requires operators to return the washer removed from service to BRP-Powertrain GmbH & Co. KG. This AD does not.
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.
