## Abstract

This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France model helicopters that requires operators to either temporarily or permanently secure the electrical bonding braid (bonding braid) that is installed on the left cyclic pitch control stick base within 10 hours time-in-service (TIS) and, if temporarily secured, installing a permanent attachment system for the bonding braid within 500 hours TIS or 12 months, whichever occurs first. This amendment is prompted by a report of a bonding braid twisting around the attachment nut installed on the bolt that connects the roll channel torque link to the left-hand cyclic pitch control stick. The actions specified by this AD are intended to prevent an unsecured bonding braid from restricting travel to the cyclic pitch control stick, and subsequent loss of control of the helicopter.
