| Background: | The EASA has received a report of a rear hinged door on an AS 332 L1 helicopter opening in-flight, without loss of the door. Investigation revealed incorrect positioning of a door catch, which induced incorrect locking and resulted in the uncontrolled opening of the door. This condition, if not detected and corrected, could lead to in-flight loss of the hinged door, with the potential to cause damage to the main and/or tail rotor blades, with possible loss of control of the helicopter; and creating risk of injury to persons on the ground. |
