## Abstract

We are adopting a new airworthiness directive (AD) for certain Bell Helicopter Textron Canada Limited (BHTC) Model 206 helicopters. This AD requires removing certain tension-torsion straps (TT straps) from service and is prompted by reports of corroded TT straps. These actions are intended to prevent an unsafe condition on these products.
