Airworthiness Directive · Amendment 39-21871 · Landing gear system
Stemme AG Gliders
This AD applies to Stemme AG Model Stemme S 12 gliders, serial numbers 12-002 through 12-026, inclusive, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Stemme AG Model Stemme S 12 gliders. This AD was prompted by 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 the incorrect installation of an axle connecting the main landing gear (MLG) to the center steel frame. This AD requires inspecting the MLG installation and repairing if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
(1) Before further flight after the effective date of this AD, visually inspect the MLG left-hand and right-hand legs for proper installation as depicted in Figure 3 of Stemme Service Bulletin No. P062-980037, Revision 00, dated June 5, 2019 (SB P062-980037).
(2) If the MLG installation is not as depicted in Figure 3 of SB P062-980037, before further flight, inspect the MLG installation for damage in accordance with the Actions section, Action 2, in SB P062-980037, except you are not required to contact Stemme if there is damage. Instead, repair any damage using a method approved by the FAA or the European Union Aviation Safety Agency (EASA).
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.
