SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
Hartzell Propeller Inc. ( )HC-( )2Y( )-( ) series propellers with non-
suffix serial number (SN) propeller hubs installed on Lycoming O-, IO-,
LO-, and AEIO-360 series reciprocating engines. This AD requires
initial and repetitive eddy current inspections (ECI) of the front
cylinder half of the propeller hub for cracks and removing cracked hubs
from service before further flight. In addition, this AD allows
installation of an improved design propeller hub (suffix SN ``A'' or
``B'') as terminating action to the repetitive ECI. This AD results
from a report of a propeller blade separating from a propeller hub. We
are issuing this AD to prevent failure of the propeller hub causing
blade separation and subsequent loss of airplane control.
DATES: This AD becomes effective September 25, 2006. The Director of
the Federal Register approved the incorporation by reference of certain
publications listed in the regulations as of September 25, 2006.
We must receive any comments on this AD by November 7, 2006.
