## Abstract

This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron, A Division of Textron Canada (BHT), Model 407 helicopters. This action requires a fuel filler cap assembly shimming and electrical bonding procedure. This amendment is prompted by the FAA's determination, based on information from the manufacturer, that electrical bonding may be inadequate. The actions specified in this AD are intended to prevent a lack of electrical bonding that could result in an electrical arc, ignition of fuel vapors, and an onboard fire.
