Airworthiness Directives; Various Aircraft Equipped with Wing Lift Struts
We are revising Airworthiness Directive (AD) 99-01-05 for certain aircraft equipped with wing lift struts. AD 99-01-05 required repetitively inspecting the wing lift struts for corrosion; repetitively inspecting the wing lift strut forks for cracks; replacing any corroded wing lift strut; replacing any cracked wing lift strut fork; and repetitively replacing the wing lift strut forks at a specified time for certain airplanes. AD 99-01-05 also required incorporating a ``NO STEP'' placard on the wing lift strut. Since we issued AD 99-01-05, we were informed that paragraph (c) had been misinterpreted and caused confusion. This AD clarifies the intent of the language in paragraph (c) of AD 99-01-05 and retains all other requirements of AD 99-01-05. We are issuing this AD to correct the unsafe condition on these products.
Special Conditions: Cessna Model 680 Series Airplanes; Aircraft Electronic System Security Protection From Unauthorized External Access
These special conditions are issued for the Cessna Model 680 Series airplanes. These airplanes will have a novel or unusual design feature associated with the architecture and connectivity capabilities of the airplanes' computer systems and networks. Connectivity to, or access by, external systems and networks may result in security vulnerabilities to the airplanes' systems. The proposed network architecture includes the following connectivity between systems: 1. Airplane control, communication, display, monitoring and navigation systems, 2. Operator business and administrative support systems, and 3. Passenger entertainment systems, and access by systems external to the airplane. 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: Cessna Model 680 Series Airplanes; Aircraft Electronic System Security Isolation or Protection From Internal Access
These special conditions are issued for the Cessna Model 680 series airplanes. These airplanes will have novel or unusual design features associated with connectivity of the passenger service computer systems to the airplane critical systems and data networks. The network architecture is composed of several connected networks including the following: 1. Flight-Safety related control and navigation systems, 2. Operator business and administrative support, and 3. Passenger entertainment. 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.
