Various non-limiting embodiments of a tool for actuating a valve, a method for making a tool for actuating a valve, and a method for actuating a valve, are provided. In one example, the tool includes a shaft defining a longitudinal axis and configured to transfer force to the valve for actuating the valve. A body has a wall surrounding a portion of the shaft. The wall defines a track that is formed therein and that has a track section substantially parallel to the longitudinal axis. A positive feature is coupled to the shaft and disposed in the track. The shaft is slidingly coupled to the body and when a force is applied to the shaft in a direction aligned with the longitudinal axis, the shaft moves relative to the body and the positive feature moves through the track section that restricts the shaft from being rotated about the longitudinal axis.

A fuel drain engagement tool and a method for draining fuel from a fuel tank are provided. In one example, a fuel drain engagement tool includes a housing. An engagement mechanism is coupled with the housing and extending upward therefrom. The engagement mechanism is configured to engage a fuel drain valve and to move between a contracted state and an expanded state. A compression applicator is coupled with the housing and is positioned to engage the engagement mechanism when the compression applicator is compressed to apply a force to the engagement mechanism that causes the engagement mechanism to move from the expanded state to the contracted state.

The invention relates to the field of aeronautical propulsion, and more particularly an on-board drainage reservoir of an aircraft engine, the on-board reservoir including a first compartment with a first intake passage for receiving fluid drained from the engine, a first closeable emptying passage, and a first quality sensor assembly for detecting at least one quality parameter of the fluid drained from the engine.

A fuel system for an aircraft is provided including a fuel tank configured to receive fuel and a fuel pump. The fuel pump includes a motor disposed proximate the fuel tank. The fuel pump further includes a power supply in electrical communication with the motor and disposed outside the fuel tank. The fuel pump further includes an impeller disposed within the fuel tank and rotatably coupled to the motor. The impeller includes a shaft having a first end and a second end spaced from the first end with the motor coupled to the first end. The shaft has a resistivity greater than the resistivity of the fuel tank between the first end and the second end to minimize electrical transfer between the motor and the fuel.

A noise attenuating device for reducing acoustic resonance in a cavity of an aircraft with an opening in a skin of the aircraft defining a first surface area and an opening peripheral edge includes a connection mechanism for securing the noise attenuating device in proximity to the opening in the skin of the aircraft and an exterior surface. The exterior surface defines a second surface area that is less than the first surface area of the opening and a device peripheral edge, which has a first section having an edge profile complimentary to at least a portion of the opening peripheral edge and a second section having an indented edge profile in relation to the first section such that when the noise attenuating device is secured within the opening, at least one gap is formed between the device peripheral edge and the opening peripheral edge.
