What is the action if the tow pin is missing or damaged during preparation?

• A. Do not tow; tag out; request replacement pin; repair before moving
• B. Proceed with tow; ignore pin.
• C. Inform maintenance after moving.
• D. Use a substitute pin from another unit.

Answer: (A)

When the tow pin is missing or damaged, the secure connection between the tow bar and the aircraft cannot be guaranteed, creating a risk of the tow bar detaching or the nose gear being damaged during movement. The correct action is to stop towing, tag out the tow system to prevent inadvertent use, request a replacement pin, and repair or replace it before moving the aircraft. Tagging out communicates that this equipment is not safe to operate until the pin is restored properly and verified. Proceeding without the pin or using an unapproved substitute could lead to equipment failure or injury, and informing maintenance after moving does not prevent the safety risk.
