Bell Helicopter Textron Canada Limited Helicopters
This AD applies to Bell Helicopter Textron Canada Limited 407.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
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
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
