What should be done immediately after detecting a fuel leak?

After detecting a fuel leak, the most important and appropriate action is to notify the maintenance team. Fuel leaks can pose significant safety hazards, including fire risks and potential environmental contamination, so promptly informing the maintenance team allows for an immediate assessment of the situation. They can then implement necessary safety protocols, work towards identifying the source of the leak, and perform repairs or necessary maintenance to mitigate any risks associated with the leak.

It's crucial to take these actions quickly because delaying notification or attempting to handle the situation without proper training and equipment can lead to dangerous outcomes. Ignoring the leak, taking a test flight, or waiting for the leak to stop are not responsible actions, as they could exacerbate the situation and endanger both personnel and the aircraft. Prioritizing safety through proper communication and immediate action is imperative in dealing with fuel leaks in aviation scenarios.
