Airworthiness Directives; Airbus Model A300 B2-1C, B2-203, B2K-3C, B4-103, B4-203, B4-2C Airplanes; Model A310 Airplanes; and Model A300 B4-601, B4-603, B4-605R, B4-620, B4-622, and B4-622R Airplanes
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:
Airworthiness Directives; Empresa Brasileira de Aeronáutica S.A. (EMBRAER) Model EMB-500 Airplanes
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: It has been found the possibility of elevator mass balance fasteners becoming slack under certain conditions. The loose of at least two fasteners may lead to an unbalance condition, which may induce flutter on airplane elevators.
Airworthiness Directives; ZLT Zeppelin Luftschifftechnik GmbH & Co KG Model LZ N07-100 Airships
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: The manufacturer has advised of receiving a report that during start up on ground a RH propeller gear box (PGB) on the airship has failed resulting in free rotation of the propeller. Investigation performed by the manufacturer revealed that the bevel gear in the propeller gearbox had cracked near the hub area. During an extensive metallurgical investigation of the cracked bevel gear some different manufacturing deviations outside of the specifications were detected. Deviations in the heat treatment, wall thickness of the bevel gear near the hub area, and score marks caused during the production process have been established as causal factors for this failure.
Airworthiness Directives; Vulcanair S.p.A. Models P 68, P 68B, P 68C, P 68C-TC, and P 68 “OBSERVER” Airplanes
We propose to supersede Airworthiness Directive (AD) 85-08-04, which applies to certain Vulcanair S.p.A. (Vulcanair) Models P 68, P 68B, P 68C, P 68C-TC, and P 68 ``OBSERVER'' airplanes. AD 85-08-04 currently requires you to repetitively visually inspect the front and rear wing spars for cracks. If cracks are found, AD 85-08-04 requires you to modify the wing spars. The wing spar modification terminates the repetitive inspection AD action and may be installed before cracks develop. Since we issued AD 85-08-04, the manufacturer revised the modification kit and identified additional airplane serial numbers that require the inspection and/or modification. Consequently, this proposed AD would retain the actions of AD 85-08-04, allow you to install the revised modification kit, and add additional serial numbers to the Applicability section. We are proposing this AD to detect and correct cracks in the front and rear wing spar, which could result in the wing separating from the airplane. This failure could lead to loss of control.
Fifteenth Meeting: RTCA Special Committee 203/Unmanned Aircraft Systems
The FAA is issuing this notice to advise the public of a meeting of RTCA Special Committee 203, Unmanned Aircraft Systems.
Airworthiness Directives; Dassault Model Falcon 10 Airplanes; Model Fan Jet Falcon Airplanes; Model Mystere-Falcon 200 Airplanes; Model Mystere-Falcon 20-C5, 20-D5, 20-E5, and 20-F5 Airplanes; Model Falcon 2000 and Falcon 2000EX Airplanes; and Model Mystere-Falcon 50 and 900, and Falcon 900EX Airplanes
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:
Airworthiness Directives; Boeing Model 727-281 Airplanes Equipped With Auxiliary Fuel Tanks Installed in Accordance With Supplemental Type Certificate SA3449NM
We are adopting a new airworthiness directive (AD) for certain Boeing Model 727-281 airplanes. This AD requires deactivation of Rogerson Aircraft Corporation auxiliary fuel tanks. This AD results from fuel system reviews conducted by the manufacturer, which identified potential unsafe conditions but has not provided associated corrective actions. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
