Abstract
The FAA is adopting a new airworthiness directive (AD) for Hoffmann Propeller GmbH & Co KG (Hoffmann Propeller) models HO-V343 and HO-V343K propellers. This AD requires initial and repetitive visual inspections of propeller blades for blade shake and blade nut preload. This AD also requires initial and repetitive eddy current inspections of blade hubs for damage and cracks. This AD results from a report of a blade separating from either a model HO-V343 or HO-V343K propeller. We are issuing this AD to prevent propeller hub failure and blade separation due to an unknown root cause, leading to damage and possible loss of control of the airplane.
