## Summary

The FAA is withdrawing a notice of proposed rulemaking (NPRM) that proposed to adopt a new airworthiness directive (AD) that would have applied to Scotts-Bell 47 Inc. (Scotts-Bell) (type certificate previously held by Bell Helicopter Textron Inc.) 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. The NPRM would have required repetitively inspecting and adjusting the throttle linkage. The NPRM was prompted by reports of the throttle linkage separating from the engine carburetor shaft, which could result in loss of throttle control. Since issuance of the NPRM, the FAA has determined, based upon the available information, that there is not an unsafe condition in the product that is likely to develop in other products of the same type design. Accordingly, the NPRM is withdrawn.
