Airworthiness Directive · Amendment 39-17674 · Power plant
XtremeAir GmbH Airplanes
This AD applies to XtremeAir GmbH Model XA42 airplanes, all serial numbers, that:
(1) Are certificated in any category; and
(2) have engine mount part number (P/N) XA42-7120-151 (manufactured by Szel-Tech), all serial numbers up to and including 036, installed.
We are adopting a new airworthiness directive (AD) for XtremeAir GmbH Model XA42 airplanes. 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 cracks in a weld seam between the lower left landing gear attachment bearing and the lower engine mount to the firewall attachment plate, which could reduce the structural integrity of the airplane and could result in engine separation. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions specified in paragraphs (f)(1) through (f)(3) of this AD.
(1) Before further flight after November 25, 2013 (the effective date of this AD) inspect the welds on the engine mount part number (P/N) XA42-7120-151 (manufactured by Szel-Tech) for cracks following the Accomplishment Instructions in XtremeAir GmbH Mandatory Service Bulletin SB-2013-008, Ausgabe (English translation: Version) A.03, dated October 25, 2013. The replacement required in paragraph (f)(2) or (f)(3) of this AD may be done instead of the inspection provided it is done before further flight.
(2) If, during the inspection required in paragraph (f)(1) of this AD, a crack is found, before further flight, replace the engine mount following the Accomplishment Instructions in XtremeAir GmbH Mandatory Service Bulletin SB-2013-008, Ausgabe (English translation: Version) A.03, dated October 25, 2013.
(3) Unless the engine mount P/N XA42-7120-151 is replaced with a serviceable part as specified in paragraph (f)(2) of this AD, within the next 10 hours TIS after November 25, 2013 (the effective date of this AD), replace the engine mount following the Accomplishment Instructions in XtremeAir GmbH Mandatory Service Bulletin SB-2013-008, Ausgabe (English translation: Version) A.03, dated October 25, 2013. Acrobatic flight is prohibited during these 10 hours.
