Airworthiness Directives; General Electric Company (GE) CF34-1A, CF34-3A, and CF34-3B Series Turbofan Engines
The FAA proposes to adopt a new airworthiness directive (AD) for GE CF34-1A, CF34-3A, and CF34-3B series turbofan engines. This proposed AD would require: Removing from service certain part number (P/N) and serial number (SN) fan blades within compliance times specified in this proposed AD, inspecting the fan blade abradable rub strip on certain engines for wear, inspecting the fan blades on certain engines for cracks, and inspecting the aft actuator head hose fitting for correct position, and if necessary repositioning. This proposed AD results from a report of an under-cowl fire, and a failed fan blade. We are proposing this AD to prevent failure of certain P/N and SN fan blades and aft actuator head hoses, which could result in an under-cowl fire and subsequent damage to the airplane.
Airworthiness Directives; Aeromot-Industria Mecanico Metalurgica ltda. Model AMT-100 Gliders as Modified to AMT-200 and Models AMT-200, AMT-200S, and AMT-300 Gliders
We propose to adopt a new airworthiness directive (AD) for the products listed above. 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:
Eighth Meeting, Special Committee 211, Nickel-Cadmium, Lead Acid and Rechargeable Lithium Batteries
The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 211, Nickel-Cadmium, Lead Acid and Rechargeable Lithium Batteries.
Special Conditions: Boeing Model 747-8/-8F Airplane, Additional Airframe Structural Design Requirements Related to Sudden Engine Stoppage Due to Fan Blade Failures
This document proposes special conditions for the Boeing Model 747-8/-8F airplane. This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. These design features include larger engines with large bypass fans capable of producing much larger and more complex dynamic loads. 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. Additional special conditions will be issued for other novel or unusual design features of the Boeing 747-8/-8F airplanes.
Special Conditions: Rosemount Aerospace Inc., Modification to Boeing 737-600, -700, -800, and -900 Series Airplanes: Lithium Battery Systems
These special conditions are issued for the Boeing 737-600, - 700, -800, and -900 Series airplanes. These airplanes, as modified by Rosemount Aerospace Inc., will have a novel or unusual design feature associated with the installation of lithium batteries. 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: TTF Aerospace, LLC, Modification to Boeing Model 767-400 Series Airplanes; Aft Lower-Lobe Crew-Rest Module (CRM)
These special conditions are issued for Boeing Model 767-400 series airplanes. These airplanes, modified by TTF Aerospace, LLC (TTF), will have a novel or unusual design feature associated with an aft, lower-lobe, crew-rest module (CRM). 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.
Establishment of Class E Airspace; Ten Sleep, WY
This action will establish Class E airspace at Ten Sleep, WY. Additional controlled airspace is necessary to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) at Red Reflet Ranch Airport, Ten Sleep, WY. This will improve the safety of Instrument Flight Rules (IFR) aircraft executing the new RNAV GPS SIAP at Red Reflet Ranch Airport, Ten Sleep, WY.
Special Conditions: Dassault Falcon 2000 Series Airplanes; Aircell Airborne Satcom Equipment Consisting of a Wireless Handset and Associated Base Station, With Lithium Battery Installations
These special conditions are issued for the Dassault Falcon 2000 series airplanes. These airplanes, as modified by Aircell LLC, will have a novel or unusual design feature associated with the Aircell airborne satcom equipment (ASE) which use 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: Boeing Model 747-8/-8F Airplane, Interaction of Systems and Structures
This notice proposes special conditions for the Boeing Model 747-8/-8F airplane. This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. These design features include their effects on the structural performance. 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. Additional special conditions will be issued for other novel or unusual design features of the Boeing 747-8/-8F airplanes.
Airworthiness Directives; McDonnell Douglas Model DC-8-50 Series Airplanes; Model DC-8F-54 and DC-8F-55 Airplanes; Model DC-8-60 Series Airplanes; Model DC-8-60F Series Airplanes; Model DC-8-70 Series Airplanes; and Model DC-8-70F Series Airplanes
We are adopting a new airworthiness directive (AD) for all McDonnell Douglas airplanes identified above. This AD requires revising the airplane flight manual to provide the flightcrew with procedures to preclude dry running of the fuel pumps. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent pump inlet friction (i.e., overheating or sparking) when the fuel pumps are continually run as the center wing fuel tank becomes empty, and/or electrical arc burnthrough, which could result in a fuel tank fire or explosion.
