Special Conditions: Embraer S.A., Model EMB-550 Airplane; Installation of Rechargeable Lithium Batteries
These special conditions are issued for the Embraer S.A. Model EMB-550 airplanes. This airplane will have a novel or unusual design feature associated with the installation of a satellite communication system that uses rechargeable lithium battery technology. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These 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: Embraer S.A.; Model EMB-550 Airplane; Flight Envelope Protection: High Incidence Protection System
This action proposes special conditions for the Embraer S.A. Model EMB-550 airplane. This airplane will have a novel or unusual design feature when compared to the state of technology and design envisioned in the airworthiness standards for transport category airplanes. This design feature is a high incidence protection system that limits the angle of attack at which the airplane can be flown during normal low speed operation. 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.
Noise Exposure Map; Notice for Merrill Field Airport, Anchorage, AK
The Federal Aviation Administration (FAA) announces its determination that the noise exposure maps submitted by Municipality of Anchorage, for Merrill Field Airport under the provisions of 49 U.S.C. 47501 et. seq (Aviation Safety and Noise Abatement Act) and 14 CFR part 150 are in compliance with applicable requirements.
Proposal To Consider the Impact of One Engine Inoperative Procedures in Obstruction Evaluation Aeronautical Studies
The FAA will hold a public meeting to discuss its proposal to consider the impact of one engine inoperative procedures during aeronautical studies. This proposal was published in the Federal Register on April 28, 2014. During the meeting, the FAA will explain the proposal and respond to questions seeking clarification of the proposed policy. In addition, the FAA is extending the time period for which the public may submit written comments for an additional 30 days.
Airworthiness Directives; Costruzioni Aeronautiche Tecnam srl Airplanes
We are adopting a new airworthiness directive (AD) for Costruzioni Aeronautiche Tecnam srl Model P2006T airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 a cracked engine mount. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France) Helicopters
We are publishing a new airworthiness directive (AD) for certain Airbus Helicopters (previously Eurocopter France) Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, AS350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters, which was sent previously to all known U.S. owners and operators of these helicopters. This AD requires repetitively inspecting certain reinforcement angles of the rear structure to tailboom junction frame (reinforcement angles) for a crack, and repairing any cracked reinforcement angle. This AD is prompted by a report that cracks were found in the reinforcement angles on several AS355 helicopters. These actions are intended to detect a crack in the reinforcement angle, which if not corrected, could result in loss of the tailboom and subsequent loss of control of the helicopter.
Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France) (Airbus Helicopters) Helicopters
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model SA-365N, SA-365N1, AS-365N2, and AS 365 N3 helicopters to require repetitively inspecting frame number (No.) 9 for a crack. This AD was prompted by a report of a crack in frame No. 9 on an AS365 helicopter. The actions of this AD are intended to detect a crack and prevent loss of structural integrity and subsequent loss of control of the helicopter.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, A330-200 Freighter, and A330-300 series airplanes; and Model A340-200, A340-300, A340-500, and A340-600 series airplanes. This AD was prompted by a non-connection of the constant speed motor/generator (CSM/G) during a final assembly operational test. This AD requires a detailed inspection of the connector wires for connector 1XE-A of the generator control unit (GCU)-CSM/ G for discrepancies (evidence of arcing or overheating damage), and related investigative and corrective actions if necessary. We are issuing this AD to detect and correct incorrect locking of contacts into connector 1XE-A of the GCU-CSM/G, which could result in a loss of contact continuity and lead to the CSM/G not operating, which, in conjunction with an emergency electrical configuration loss of the main electrical system or total engine flameout, could adversely affect the airplane's safe flight.
Airworthiness Directives; Dowty Propellers Propellers
We are revising airworthiness directive (AD) 2008-21-07 for certain Dowty Propellers model R408/6-123-F/17 propellers. AD 2008-21- 07 required initial and repetitive inspections of the blade bonded metallic leading edge (L/E) guards for correct bonding until they accumulate more than 1,200 flight hours (FH) time-in-service. This AD requires the same inspection and replacement requirements of AD 2008- 21-07. This AD also provides an optional terminating action to those requirements. This AD was prompted by updated service bulletins that identify terminating action to the requirements of AD 2008-21-07. We are issuing this AD to prevent the loss of the bonded metallic L/E guard of the propeller, which could result in damage to the propeller or to the airplane, or injury to personnel.
