AD 2020-13-03 Airworthiness Directives; XtremeAir GmbH Airplanes
Models named: XA42. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to XtremeAir GmbH Model XA42 airplanes, all serial numbers, certificated in any category.
Compliance
For airplanes with an engine mount part number (P/N) XA42-7120-151 installed, unless already done, do the following actions in paragraphs (f)(1) and (2) of this AD. (1) Before the next acrobatic flight after July 15, 2020 (the effective date of this AD) or before the engine mount accumulates 50 hours time-in-service (TIS), whichever occurs later, and thereafter at intervals not to exceed 10 acrobatic flights, visually inspect the junction of the left-hand and right-hand diagonal struts of the engine mount, forward of the oil cooler, for cracks in the area shown in the photographs in XtremeAir GmbH Mandatory Service Bulletin SB-XA42-2019-008, Issue B.00, dated December 4, 2019. For purposes of this AD, an acrobatic flight is counted for each flight during which a load factor of 6g is exceeded. (i) If there is a crack, before further flight, replace the engine mount with an airworthy engine mount with zero hours TIS, an engine mount that has passed the inspection required by this AD, or an engine mount that is not P/N XA42-7120-151. (ii) After completing the initial inspection, begin or continue to count the acrobatic flights and record in the maintenance records. (2) As of July 15, 2020 (the effective date of this AD), do not install on the airplane an engine mount P/N XA42-7120-151 unless it is an airworthy engine mount with zero hours TIS or is an engine mount that has passed the inspection required by this AD.
Required actions
For airplanes without engine mount P/N XA42-7120-151 installed, as of July 15, 2020 (the effective date of this AD), do not install engine mount P/N XA42-7120-151.
Unsafe condition
This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and address an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracking of the diagonal struts of the engine mount frame. The FAA is issuing this AD to prevent the in-flight detachment of the engine, which could result in loss of control of the airplane.
Affected ADs
This AD replaces AD 2018-07-15, Amendment 39-19246 (83 FR 15036, April 9, 2018).
