Explain the procedure to follow when discovering undocumented damage on an aircraft during a pre-departure walk-around inspection?

When discovering undocumented damage on an aircraft during a pre-departure walk-around inspection, a specific procedure must be followed to ensure flight safety. First, immediately notify the flight crew of the damage. Provide them with a clear and concise description of the damage, including its location, size, and nature. Do not attempt to assess the severity of the damage yourself; that is the responsibility of qualified maintenance personnel. Next, document the damage thoroughly. Take photographs of the damage from multiple angles, including close-up shots and wider shots that show its location on the aircraft. Make a written record of the damage, including the date, time, location, and a detailed description of the damage. The written record should be clear and legible. Do not attempt to repair the damage yourself. Any repairs must be performed by qualified maintenance personnel. Wait for maintenance personnel to arrive and assess the damage. Provide them with all of the information that you have gathered, including the photographs and written record. Follow the instructions of the maintenance personnel. They will determine whether the damage is within acceptable limits for dispatch or whether repairs are necessary. If repairs are necessary, the aircraft cannot be released for flight until the repairs have been completed and the aircraft has been certified as airworthy. Even seemingly minor damage can have a significant impact on flight safety. For example, a small dent in the wing can affect the aircraft's aerodynamics, while a scratch on a window can reduce visibility. It is essential to report all damage, no matter how small it may seem. A detailed record of all discovered damage is essential for maintaining the aircraft's airworthiness and ensuring the safety of flight.
