Abstract: A device for monitoring the sealing state of a casing (2) of a transmission box (1) of a rotorcraft. An open airflow circuit (7) fitted with a suction generator member (10) is connected to a vent (5) of the casing (2). Regulator means (12) maintain stable suction in the airflow circuit (7) relative to a setpoint threshold (S), the regulator means being controlled in response to a pressure gauge (13) for measuring the suction generated inside the airflow circuit (7). The device is used on the ground to detect a source of leakage in the casing (2) and in flight to retain lubricant inside the casing (2) in the event of there being a source of leakage.

Abstract: A method and a device (1) for monitoring and controlling a test bench (2) provided with control elements (3) for controlling the bench (2) and with an interface (4) including display elements (41) and also communication elements (42), the control elements (3) being suitable for controlling the test bench (2) The device (1) is also provided with a set (6) of members for determining the configuration of the test and with at least one acquisition input (3?) for acquiring at least one test result measured by at least one acquisition element of the test bench (2)
