## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to BHTC Model 407 helicopters, that requires modifying the door latch assemblies on all four crew and passenger doors. This amendment is prompted by an incident that occurred during a manufacturer's flight test, in which a door latch assembly broke, preventing occupants in the helicopter from opening the door. The actions specified by this AD are intended to prevent a door latch rod assembly from disengaging from the door handle and preventing helicopter occupants from opening the door.
