What is breakdown maintenance?

Breakdown maintenance is maintenance performed on a piece of equipment that has broken down, faulted, or otherwise cannot be operated. The goal of breakdown maintenance is to fix something that has malfunctioned. To the contrary, preventive maintenance is performed in order to keep something running.

Sometimes breakdown maintenance is performed because of an unplanned event. For example, if a critical piece of machinery breaks, the maintenance is performed because of the imminent need for that machine to operate again. However, breakdown maintenance can be planned for in advance, which is what we might call “good” breakdown maintenance.

types of breakdown maintenance

Planned breakdown maintenance

Planned breakdown maintenance means that the organization is prepared for a breakdown and even expects it to happen. The equipment runs until it breaks, which initiates a run to failure (RTF) trigger. While RTF triggers can be unplanned, breakdown maintenance plans use RTF as a way of lowering the cost of maintenance.

This kind of plan needs to be rigorously documented and controlled. Employees should be clear on exactly which parts will break down and which parts will be maintained normally via preventive maintenance. Without these checks, a breakdown maintenance plan can be exploited or run awry.

Unplanned breakdown maintenance

Unplanned breakdown maintenance, on the other hand, occurs when a piece of equipment fails or breaks unexpectedly—also called an unplanned downtime event. While some facilities may not utilize a planned breakdown maintenance plan, nearly every facility needs resources in place for unplanned breakdown maintenance. After all, every piece of equipment will break or fault at some point in its life.

examples of breakdown maintenance

Breakdown maintenance is unique in its applications because it cannot be used with certain industries or products, especially ones that involve health and safety. This means that breakdown maintenance is most frequently used when parts are inexpensive or nonessential.

Here are some examples in which breakdown maintenance is applicable:

  • Equipment can’t be repaired at all (inaccessible, designed to not be repaired)

  • Asset consists of inexpensive or easy-to-replace parts

  • Non-critical pieces of equipment (like hand tools)

  • Objects/equipment that are disposable or meant to be replaced at the end of their lifespan

  • Short-life assets (batteries, high flow pumps)

As you can see from these examples, breakdown maintenance becomes viable when there’s no inherent safety risk to letting a part or piece of equipment break. As an example, consider a facility’s light bulbs. If a light bulb is not linked to a safety feature, it doesn’t make financial sense to replace it before it has burned out.

However, breakdown maintenance is absolutely not viable when people’s lives can be endangered by a part or product breaking. For example, the aviation industry cannot rely on parts breaking down to fix them because doing so could threaten the personal wellbeing and safety of people on planes. This is also true for tire manufacturers who are responsible for road safety. When it comes to people’s lives, preventive and predictive maintenance are the right choice.

Advantage of breakdown maintenance

Failed equipment can lead to disastrous consequences, but a clearly-documented breakdown maintenance plan can actually have a few significant benefits for an organization.

  • Minimizes maintenance cost by cutting out unnecessary preventive maintenance

  • Lowers cost of replacing disposable items frequently (light bulbs, tools, fuses)

  • Downtime for repairs is consolidated

  • Low staffing needs

  • Simple and easy to understand when maintenance is required
