## Abstract

We are adopting a new airworthiness directive (AD) for certain Hoffmann GmbH & Co. KG model HO-V 62 propellers. This AD was prompted by the failure of the propeller blade lag screws. This AD requires removal of the affected propeller blades and installation of modified propeller blades marked with change letter "A" or "B." We are issuing this AD to address the unsafe condition on these products.
