Airworthiness Directives; Boeing Model 747-200F, 747-200C, 747-400, 747-400D, and 747-400F Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Boeing Model 747-200F, 747-200C, 747-400, 747-400D, and 747- 400F series airplanes. This proposed AD would require repetitive inspections for cracking of certain fuselage internal structure, and repair if necessary. This proposed AD is prompted by fatigue tests and analysis that identified areas of the fuselage where fatigue cracks can occur. We are proposing this AD to prevent loss of the structural integrity of the fuselage, which could result in rapid depressurization of the airplane.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135BJ, -135ER, -135KE, -135KL, and -135LR Airplanes; and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER airplanes listed above. This proposed AD would require modifying the drain system of the auxiliary power unit (APU) by installing a scavenge pump and, for certain airplanes, replacing the APU exhaust assembly. This proposed AD results from a report of fuel leaking from the APU feeding line and accumulating inside the APU compartment because the drain system is inadequate when the APU is running. We are proposing this AD to prevent fuel accumulation and subsequent flammable fuel vapors in the APU cowling, which, combined with an ignition source, could result in a fire or explosion.
Airworthiness Directives; Airbus Model A300 B2 and A300 B4 Series Airplanes; Model A300 B4-600, B4-600R and F4-600R Series Airplanes, and Model A300 C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and Model A310-200 and -300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for all the Airbus models identified above. This AD requires modifying the electrical power supply logic for the integral lighting of the standby horizon indicator in the cockpit, accomplishing repetitive operational tests of the integral lighting logic system, and performing corrective action if necessary. This AD is prompted by a report of temporary loss of six cathode ray tube (CRT) flight displays and the integral lighting of the standby horizon indicator backlight in the cockpit during takeoff, due to failure of the normal electrical power circuit. That power circuit supplies power to both the CRTs and the standby horizon indicator backlight. We are issuing this AD to prevent loss of the integral lighting due to failure of the normal electrical power circuit, which could result in inability of the pilot to read the backup attitude information during takeoff, and possible deviation from the intended flight path.
Airworthiness Directives; Airbus Model A330-200 and -300 Series Airplanes; and Model A340-200 and -300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Airbus transport category airplanes, identified above. This AD requires an inspection to determine if a certain lower pin (p-pin) of the retraction actuator of the main landing gear (MLG) is installed. If the affected p-pin is installed, this AD requires a one-time inspection of the p-pin for correct grease hole position and cracking; repetitive daily inspections for pin migration; and eventual replacement of all p- pins with new p-pins. For any p-pin that is cracked or shows pin migration, this AD requires immediate replacement with a new p-pin. Replacing the p-pin with one that is correctly manufactured (i.e., that has the correct grease hole position) is terminating action for the repetitive inspections. This AD results from a report that a cracked p- pin was found when the MLG was removed for overhaul. We are issuing this AD to prevent failure of the p-pin, which could result in degradation of the MLG structural integrity and possible hazardous landing.
Airworthiness Directives; Boeing Model 767-200 and 767-300 Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767-200 and 767-300 series airplanes. This AD requires performing a general visual inspection to determine the part number of the I-beams of the center overhead stowage bin modules to identify I-beams having 9.0g (gravitational acceleration) tie rods attached and to determine the configuration of the center overhead stowage bin modules. For certain center overhead stowage bin modules, this AD requires installing support straps. This AD results from tests conducted by the airplane manufacturer. We are issuing this AD to prevent failure of the attachment of the 9.0g tie rods to the center overhead stowage bin modules. This failure could result in collapse of those stowage bin modules, and consequent injury to passengers and crew and interference with their ability to evacuate the airplane in an emergency.
