How should issues with a tow bar latch be handled?

• A. Do not tow; tag out; replace latch; notify maintenance.
• B. Proceed with towing and ignore latch.
• C. Tighten latch and continue.
• D. Lubricate latch and resume.

Answer: (A)

When a tow bar latch is defective, treat it as a safety-critical defect and keep the tow bar out of service. The latch is essential to secure the connection during towing, and a fault can lead to detachment, loss of control, or damage to the aircraft and personnel.

That’s why the proper action is to not tow, tag out the equipment, replace the latch, and notify maintenance. Tagging out clearly marks the tow bar as inoperative, preventing accidental use, while replacing the latch restores a secure connection and ensures a qualified technician can verify the repair. Notifying maintenance gets the issue documented and repaired correctly.

Continuing to tow or ignoring the latch is unsafe because the fault could fail during operation. Simply tightening or lubricating might mask the underlying problem or provide only a temporary, unreliable fix, which could lead to a dangerous situation later.
