                This Airworthiness Directive becomes effective on 29 September 2005.
Background:     This Directive results from the discovery during routine propeller installation that a bolt from a certain manufacture lot did not properly absorb the installation torque.  This Directive also results from the discovery that other bolts of the same part number from a different manufacture lot had material surface pitting.  This Directive is being issued to prevent propeller mounting bolt failures or improperly secured propellers, which could lead to separation of the propeller from the aeroplane.
