Airworthiness Directives; Boeing Model 747-200B, 747-300, 747- 400, 747-400D, and 747-400F Series Airplanes Equipped

Fri, Dec 28 2007 11:00:00 GMT

The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747200B, 747300, 747400, 747400D, and 747400F series airplanes. This AD requires repetitive inspections of the left and righthand flipper door assemblies of the engine
[[Page 73588]]
core cowls for migrated pins and damaged flipper doors, and corrective actions if necessary. Modification of the hinge assemblies terminates the repetitive inspections. This AD results from two reports of missing flipper doors for the engine core cowls. We are issuing this AD to detect and correct migrated hinge pins and damaged flipper doors, which could allow the flipper door to fall off, resulting in the potential for an engine fire to propagate into the flammable leakage zone of the strut and for the amount of fire extinguishing agent reaching the fire to be diluted, and subsequent uncontained fire in the engine strut.

Special Condition: Bell Helicopter Textron Canada Limited Model 429 Helicopters, High Intensity Radiated Fields

Fri, Dec 28 2007 11:00:00 GMT

This special condition is issued for the Bell Helicopter Model 429 helicopters. These helicopters will have novel or unusual design features associated with installing electrical and electronic systems that perform critical functions, including an Electronic Flight Instrument System (EFIS) and a Full Authority Digital Engine Control (FADEC). The applicable airworthiness regulations do not contain adequate or appropriate safety standards to protect systems that perform critical control functions, or provide critical displays, from the effects of highintensity radiated fields (HIRF). This special condition contains the additional safety standards that the Administrator considers necessary to ensure that critical functions of systems will be maintained when exposed to HIRF.

Special Conditions: Boeing Model 757 Series Airplanes; Seats With Non-Traditional, Large, Non-Metallic Panels

Fri, Dec 28 2007 11:00:00 GMT

These special conditions are issued for Boeing Model 757 Series Airplanes. These airplanes, as modified by Triad International Maintenance Company (TIMCO), will have a novel or unusual design feature(s) associated with seats that include nontraditional, large, nonmetallic panels that would affect survivability during a postcrash fire event. 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 787-8 Airplane; Systems and Data Networks Security-Protection of Airplane Systems

Fri, Dec 28 2007 11:00:00 GMT

These special conditions are issued for the Boeing Model 787-8 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. The architecture of the Boeing Model 7878 computer systems and networks may allow access to external systems and networks, such as wireless airline operations and maintenance systems, satellite communications, electronic mail, the Internet, etc. Onboard wired and wireless devices may also have access to parts of the airplane's digital systems that provide flight critical functions. These new connectivity capabilities may result in security vulnerabilities to the airplane's critical systems. For these design features, the applicable airworthiness regulations do not contain adequate or appropriate safety standards for protection and security of airplane systems and data networks against unauthorized access. These special conditions contain the additional
