The letter 'E' in the left-hand margin of FAA Form 7230-4 denotes a(n)

• A. Equipment malfunction or restored to service
• B. Error
• C. Invalid entry
• D. Shift change

Answer: (A)

The letter in the left margin is a quick-code that flags the type of event on the FAA Form 7230-4. Using the margin letter E means there is an equipment malfunction or the equipment has been restored to service. This matters because equipment status directly affects how you manage the workload and coordinate with maintenance and other controllers. When you log a problem, you note it with the E marker and a brief description; when the equipment is fixed and back in service, you again indicate the status change with that same margin indication and how long it was out. The other possibilities don’t fit because they refer to human error, an invalid entry, or a shift handover, which are tracked differently and aren’t signified by this margin code.
