Preventive Maintenance (R218B)

This is performed to reduce the chance of break-down. GM robots (R222A) can perform it on starships and ship’s boat.
Starship engineers can do preventive maintenance on any equipment or vehicle.

Preventive maintenance takes an entire day of work for the man or robot, who cannot do anything else, and will be
prevented from doing it by combat or some other interruption. All items and vehicles at that location get the benefit of the
maintenance. More than one engineer and/or robot at the location does not increase the benefits in any way.

If an engineer performed maintenance, all items add two (+2) to breakdown rolls that day, and add one (+1) to break-down
rolls for the next two days afterward.

If a GM robot performed maintenance, all items add one (+1) to breakdown rolls that day and the following day.
