Airworthiness Directive · Amendment 39-19246 · Power plant
XtremeAir GmbH Airplanes
Superseded. A later AD replaced this one: AD 2020-13-03. Comply with the one in force.
This AD applies to XtremeAir GmbH Model XA42 airplanes, all serial numbers, that are:
(1) Equipped with an engine mount part number (P/N) XA42-7120-151; and
(2) certificated in any category.
We are adopting a new airworthiness directive (AD) for XtremeAir GmbH Model XA42 airplanes equipped with an engine mount part number XA42-7120-151. This AD results from 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 strut of the engine mount frame. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions in paragraphs (f)(1) through (4) of this AD.
(1) Before the next acrobatic flight after April 30, 2018 (the effective date of this AD) or within 50 hours time-in-service after the installation of P/N XA42-7120-151 engine mount on the airplane, whichever occurs later, and repetitively thereafter at intervals not to exceed 10 acrobatic flight hours, inspect the engine mount following the Accomplishment Instructions in XtremeAir Mandatory Service Bulletin SB-XA42-2018-006, Issue A.00, dated March 2, 2018.
(2) After the initial inspection required in paragraph (f)(1) of this AD, acrobatic flight hours must be recorded in the maintenance records. For the purpose of this AD, we define acrobatic flight as “flight during which a load factor of 6g is exceeded.”
(3) If a crack is found during any inspection required in paragraph (f)(1) of this AD, before further flight, replace the engine mount with a serviceable part following the Accomplishment Instructions in XtremeAir Mandatory Service Bulletin SB-XA42-2018-006, Issue A.00, dated March 2, 2018. Replacement of the engine mount does not eliminate the repetitive inspection requirement in paragraph (f)(1) of this AD.
(4) After the effective date of this AD, you may install a new or used P/N XA42-7120-151 engine mount on the airplane. The used P/N XA42-7120-151 engine mount must be inspected as specified in paragraph (f)(1) of this AD and found free of cracks before installation on the airplane. The repetitive inspection requirement in paragraph (f)(1) of this AD still applies.
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.
