| 2011-33049 | Special Conditions: XtremeAir GmbH, XA42; Acrobatic Category Aerodynamic Stability | Proposed Rule | This action proposes special conditions for the XtremeAir GmbH XA42 airplane. The XA42 airplane has a novel or unusual design feature associated with its static stability. This airplane can perform at the highest level of aerobatic competition. To be competitive, the aircraft was designed with positive and, at some points, neutral stability within its flight envelope. Its lateral and directional axes are also decoupled from each other providing more precise maneuvering. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards. These special conditions are only applicable to aircraft certified solely in the acrobatic category. | 2011-12-27 | 2011 | 12 | https://www.federalregister.gov/documents/2011/12/27/2011-33049/special-conditions-xtremeair-gmbh-xa42-acrobatic-category-aerodynamic-stability | https://www.govinfo.gov/content/pkg/FR-2011-12-27/pdf/2011-33049.pdf | Transportation Department; Federal Aviation Administration | 492,159 | This action proposes special conditions for the XtremeAir GmbH XA42 airplane.
