Airworthiness Directives; Scotts-Bell 47 Inc. (Type Certificate Previously Held by Bell Helicopter Textron Inc.)
We propose to adopt a new airworthiness directive (AD) for Scotts-Bell 47 Inc. (Scotts-Bell) Model 47, 47B, 47B3, 47D, 47D1, 47E, 47G, 47G-2, 47G-2A, 47G-2A-1, 47G-3, 47G-3B, 47G-3B-1, 47G-3B-2, 47G- 3B-2A, 47G-4, 47G-4A, 47G-5, 47G-5A, 47H-1, 47J, 47J-2, 47J-2A, and 47K helicopters. This proposed AD would require repetitively inspecting and adjusting the throttle linkage. This proposed AD is prompted by reports of the throttle linkage separating from the engine carburetor shaft, which could result in loss of throttle control. The actions in this proposed AD are intended to correct an unsafe condition on these products.
Special Conditions: The Boeing Company Model 777-8 and 777-9 Airplanes; Folding Wingtips
These special conditions are issued for The Boeing Company (Boeing) Model 777-8 and 777-9 airplanes. These airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport- category airplanes. This design feature is folding wingtips. 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.
