An emergency airworthiness directive (EAD) is prompted by an error in the Illustrated Parts Catalog that incorrectly identifies applicability of a certain part-numbered blade on Agusta Model A109A and A109A II helicopters. This EAD requires replacing an affected blade with the approved part-numbered blade for the applicable model. This condition, if not corrected, could result in blade failure and subsequent loss of control of the helicopter.
