## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to Eurocopter France Model SA.315B, SA.316B, SA.316C, SA 318B, SA 318C, SA.319B, SE 313B, SE 3130, SE.3160, and SA 3180 helicopters that have certain tail rotor blades (blades) installed. This action requires reducing the service life of those blades to 400 hours time-in-service (TIS). This amendment is prompted by the discovery that 10 blades were manufactured incorrectly. This condition, if not corrected, could result in failure of a blade and subsequent loss of control of the helicopter.
