Final rule.

The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Canada Limited Model 505 helicopters. This AD was prompted by a fuel leakage discovered during fuel system crash impact testing activity. This AD requires installing a grommet around the sump drain port fitting airframe hole, as specified in a Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
