Proposed Rules

  1. Airworthiness Directives; Costruzioni Aeronautiche Tecnam srl Airplanes; [Docket No. FAA-2011-0816, Directorate Identifier 2011-CE-022-AD] We are revising an earlier NPRM for Costruzioni Aeronautiche Tecnam srl Model P2006T airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracking, bulging, deformation, or oil leakage in the lower lid of the landing gear emergency accumulator, which could result in decreasing the airplane’s structural integrity and jeopardizing the landing gear emergency extension in case of system failure in normal mode. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
  2. Airworthiness Directives; Bell Helicopter Textron, Inc. Helicopters; [Docket No. FAA-2012-0601, Directorate Identifier 2008-SW-033-AD] We propose to adopt a new airworthiness directive (AD) for the Bell Helicopter Textron, Inc. (BHTI) Model 205A, 205A-1, and 205B helicopters with certain starter/generator power cable assemblies (power cable assemblies). This proposed AD is prompted by the determination that the power cable assembly connector (connector) can deteriorate, causing a short in the connector that may lead to a fire. This AD would require replacing the power cable assemblies and their associated parts, and performing continuity readings. We are proposing this AD to prevent a short in the connector that may lead to a fire in the starter/generator, smoke in the cockpit that reduces visibility, and subsequent loss of helicopter control.
  3. Proposed Amendment of Restricted Area R-6601; Fort A.P. Hill, VA; [Docket No. FAA-2012-0561, Airspace Docket No. 12-AEA-7] This action proposes to expand the vertical limits and time of designation of restricted area R-6601, Fort A.P. Hill, VA. The U. S. Army requested this action to provide the additional airspace needed to conduct training in high-angle weapons systems employment.
