Notice of proposed rulemaking (NPRM).
Summary
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.
