  "body": "## What is a preventive maintenance inspection (PMI)?\n\nA preventive maintenance inspection is scheduled service work that records the condition of equipment at a point in time, the work performed, and the context for the next service. It is a maintenance record, not a federal annual inspection or a compliance certification.\n\n## What should a PM inspection form include?\n\nA useful PM form identifies the equipment, records the date and technician, captures the meter or odometer context where relevant, organizes observations by system, and leaves room for findings, work performed, and follow-up. The correct equipment-specific items and intervals come from the manufacturer’s documentation.\n\n## Is a PM inspection the same as a DOT inspection?\n\nNo. Preventive maintenance is scheduled service work. A federal annual DOT inspection has separate legal requirements, qualification rules, documentation, and consequences. A passing PM result does not establish compliance with a DOT annual-inspection requirement.\n\nA preventive maintenance inspection (PMI), often shortened to PM inspection, is a structured way to record a scheduled equipment visit. It turns an otherwise forgettable service stop into a record: what equipment was seen, what condition was observed, what work was completed, and what context the next technician needs.\n\nThe useful word is **record**. A blank checklist is only a starting point. The value comes from completing it against a specific asset and keeping the result available when the equipment returns.\n\n## What belongs in a PM record\n\nFor most equipment, a PM record needs four blocks of information:\n\n1. **Identify the asset.** Use the unit, asset, VIN, serial number, or other identifier that lets the customer distinguish this machine from the rest of the fleet.\n2. **Place the visit in context.** Record the date, technician, and relevant odometer, hour-meter, or operating context.\n3. **Document the observation and work.** Organize the visit by system so a reader can see what was checked, what was found, and what was repaired, adjusted, or deferred.\n4. **Make the next step clear.** Note follow-up work, a recommendation, or the information needed to plan the next service according to the manufacturer’s guidance.\n\nThis structure works because it answers the questions a customer asks after the truck, generator, or vessel is no longer in the bay: *What happened? What needs attention? When should we look at it again?*\n\n## A PM form is not a service manual\n\nThe manufacturer’s documentation remains the authority for equipment-specific procedures, intervals, limits, fluids, and parts. A PM record should preserve what the technician did under that guidance; it should not pretend that a generic online form defines the correct maintenance program for every make, model, or operating condition. For how a PM is grouped by system on specific equipment, see the [semi truck](/kb/semi-truck-preventive-maintenance-checklist), [diesel generator](/kb/diesel-generator-maintenance-checklist), and [marine diesel engine](/kb/marine-diesel-engine-maintenance-checklist) checklists.\n\n## A PM inspection is not a DOT annual inspection\n\nPreventive maintenance and a federal annual DOT inspection can happen around the same equipment, but they do different jobs. A PM visit helps maintain and document equipment. It does not certify a vehicle under 49 CFR Part 396, determine whether a vehicle is out of service, or prove compliance. Read [PM inspection vs. DOT inspection](/kb/pm-inspection-vs-dot-inspection) for the boundary.\n\n## From form to useful history\n\nFor a technician, the best PM process is one that starts with the customer and equipment already in context, then leaves a usable history instead of a disconnected file. Blue Collar Parts is built around that service-event approach for preventive maintenance. [See what the customer should receive from a PM visit](/kb/what-belongs-in-a-pm-report-for-the-customer).\n\n---\n\n*Preventive maintenance is not a federal annual inspection and does not establish regulatory compliance. Use the equipment manufacturer’s current service documentation for equipment-specific maintenance requirements.*",
