Where is one of the safety lockout pins located?

The safety lockout pin is typically found near the aft door of an aircraft. This is crucial for maintaining safety protocols during maintenance or when the aircraft is not in operation. The placement of the lockout pin near the aft door serves several purposes. It prevents the aircraft from being inadvertently powered up or engaged while personnel are working in that area, thus protecting maintenance crews and ensuring that only authorized and trained personnel can access certain functions of the aircraft during critical times.

While there may be other locations that encompass safety features or lockout mechanisms—such as within the cabin or cockpit—these are not standard locations for a lockout pin designated for safety isolation during maintenance. By being located at the aft door, the lockout pin can be quickly accessed and is immediately identifiable as part of the safety checks that crew members need to perform before commencing any works on the aircraft.
