This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 96-06-12 which was sent previously to all known U.S. owners and operators of Bell Helicopter Textron, Inc. (Bell) Model 47B, 47B-3, 47D, 47D-1, 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 47-K helicopters by individual letters. This AD requires a visual inspection of each tail rotor blade (blade) tip, abrasion strip, blade skin, and blade butt for corrosion or delamination. This amendment is prompted by reports that a number of Model 47 helicopter blades were manufactured using a clad aluminum alloy material instead of a bare aluminum alloy material. The actions specified by this AD are intended to prevent premature delamination or separation of the blade tip block or the abrasion strip, which could lead to failure of the blade and subsequent loss of control of the helicopter.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
