Airworthiness Directives; Eurocopter Deutschland GmbH Helicopters
We are revising an earlier proposed airworthiness directive (AD) for Eurocopter Deutschland GmbH (Eurocopter) Model BO-105A, BO- 105C, BO-105LS A-1, BO-105LS A-3, and BO-105S helicopters, which proposed inspecting for debonding of the erosion protective shell (abrasion strip) on the leading edge of each main rotor blade. This SNPRM proposes to revise those inspection requirements by identifying specific dates of replacement of the applicable parts and identifying a specific inspection method for debonding of an abrasion strip.
List of Units of the National Park System Exempt From the Provisions of the National Parks Air Tour Management Act
The National Parks Air Tour Management Act (NPATMA) requires the Federal Aviation Administration (FAA) and National Park Service (NPS) to develop an air tour management plan for units of the national park system where an operator has requested authority to provide commercial air tours. The FAA Modernization and Reform Act of 2012 amended various provisions of NPATMA. One provision exempted national park units with 50 or fewer annual flights from the provisions of NPATMA and requires FAA and NPS to jointly publish a list of exempt parks. This notice includes an initial list of parks that are exempt from the provisions of the NPATMA.
Special Conditions: Embraer S.A., Model EMB-550 Airplanes; Electrical/Electronic Equipment Bay Fire Detection and Smoke Penetration
This action proposes special conditions for the Embraer S.A. Model EMB-550 airplane. This airplane will have novel or unusual design features, specifically distributed electrical and electronic equipment bays in pressurized areas of the airplane. Older transport category airplane electrical/electronic equipment bay installations are located in the lower lobe where the flightcrew could determine the origin of smoke or fire by a straightforward airplane flight manual procedure. In distributed electrical/electronic bay installations it is not as straightforward. The FAA has no requirement for smoke and/or fire detection in the electrical/electronic equipment bays. To ensure effective mitigation of fires, the FAA proposes these special conditions. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. 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.
Special Conditions: Airbus, A350-900 Series Airplane; Flight Envelope Protection (Icing and Non-Icing Conditions); High Incidence Protection and Alpha-Floor Systems
This action proposes special conditions for Airbus A350-900 series airplanes. These airplanes will have novel or unusual design features associated with flight envelope protection in icing and non- icing conditions that use low speed incidence protection and an alpha- floor function that automatically advances throttles whenever the airplane angle of attack reaches a predetermined value. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. 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.
