Ask a transit maintenance director for their PM compliance rate and most can give a rough answer. Ask them to prove it with documentation an FTA Triennial Review team will accept, and the confidence usually drops. PM compliance rate is simply the percentage of scheduled preventive maintenance inspections, across PM-A, PM-B, and PM-C classes, that were actually completed within their required interval, and it is one of the first numbers a Triennial Review team asks to see backed by records. Industry guidance commonly treats 80 percent as the minimum acceptable threshold, and a fleet that cannot produce clean documentation at or above that line typically walks away with a corrective action finding, regardless of how well the actual maintenance work was performed. FleetRabbit calculates PM compliance rate automatically from real inspection records instead of asking someone to reconstruct it from memory the week before an audit. You can sign up to see your own fleet's compliance rate calculated from data you already have.
How PM Compliance Rate Is Actually Calculated
The math itself is simple. What is hard is having a clean, complete count of both numbers, especially across a fleet where PM-A, PM-B, and PM-C inspections are running on different intervals at the same time.
Every inspection that runs late, gets skipped, or is missing documentation lowers the numerator, and a fleet running PM-A, PM-B, and PM-C on separate spreadsheets often does not notice until the totals get added up for the review.
See Compliance Rate by Depot or Vehicle Class
A single fleet-wide number can hide a depot or vehicle class that is quietly falling behind. FleetRabbit breaks the compliance rate down so a problem area is visible before it drags down the whole agency's number.
Teams that sign up for FleetRabbit get this breakdown updated automatically as inspections are logged, instead of recalculating it manually before every review.
Core PM Compliance Features
Each feature below is built around what actually gets asked for during a review, not just a dashboard number. Fleets that sign up get all four working together automatically.
Automatic Rate Calculation
Compliance rate updates in real time as PM-A, PM-B, and PM-C inspections are completed, logged, or missed, with no manual tally required.
Depot and Class Breakdown
Rates can be viewed fleet-wide or broken down by depot and vehicle class, so a lagging group is visible well before an audit.
Missed Inspection Alerts
Vehicles approaching or past their PM interval are flagged automatically, giving maintenance time to close the gap before it affects the rate.
One-Click Review Export
A complete compliance rate history with supporting inspection records can be exported for any date range in a single click.
Know Your PM Compliance Rate Before the Reviewer Asks
Automatic compliance rate tracking across every PM class, depot, and vehicle, backed by the inspection records to prove it.
What an FTA Triennial Review Team Actually Checks
Reviewers are generally less interested in the final percentage than in whether it can be backed up with real records. You can book a demo to see how FleetRabbit organizes this evidence ahead of your next review.
| Review Focus | What It Confirms |
|---|---|
| Written PM schedule | The agency has a documented interval for PM-A, PM-B, and PM-C by vehicle type |
| Inspection completion records | Each scheduled inspection was actually performed within its required interval |
| Overall compliance rate | The completed-versus-scheduled ratio meets or exceeds the agency's own target |
| Corrective action history | Past compliance gaps were identified and addressed, not just noted and dropped |
Where PM Compliance Fits Broader Reporting
None of these programs treat PM compliance as an isolated number. You can book a demo to see how one compliance rate calculation supports all three at once.
FTA Triennial Review
PM compliance documentation is a standard element reviewers request as part of the maintenance program assessment.
Transit Asset Management Plan
Consistent PM completion feeds directly into the vehicle condition data agencies track under their TAM performance targets.
ADA Lift Inspection Records
Lift-equipped vehicles carry their own PM requirements, so lift inspection compliance rolls into the same overall PM compliance picture.
Manual Compliance Tracking vs. FleetRabbit
| Task | Manual Tracking | FleetRabbit |
|---|---|---|
| Calculating the compliance rate | Tallied by hand from separate PM-A/B/C logs | Calculated automatically and updated in real time |
| Spotting a lagging depot or class | Not visible until totals are combined | Broken down by depot and vehicle class automatically |
| Catching a missed inspection | Found only when the schedule is reviewed manually | Flagged automatically as vehicles approach their interval |
| Preparing records for a Triennial Review | Days spent assembling logs by hand | Full compliance history exported in one click |
You can sign up to have your compliance rate ready well before your next review is scheduled.
Turn PM Compliance Into a Number You Can Prove
Real-time compliance rate tracking, depot-level visibility, and one-click exports for every Triennial Review.
Frequently Asked Questions
What is PM compliance rate in transit maintenance
PM compliance rate is the percentage of scheduled preventive maintenance inspections, across PM-A, PM-B, and PM-C classes, that were actually completed within their required interval. It is calculated by dividing completed on-schedule inspections by total inspections scheduled for the period.
What compliance rate do FTA reviewers generally expect to see
Industry guidance commonly treats 80 percent as the minimum acceptable threshold. A rate below that level typically draws a finding during a Triennial Review, along with a request for a corrective action plan.
Can compliance rate be tracked separately by depot or vehicle class
Yes. FleetRabbit calculates compliance rate at the fleet-wide level as well as broken down by depot and vehicle class, so a lagging group is visible before it affects the overall number.
Does PM compliance rate connect to ADA lift inspection requirements
Yes. Lift-equipped vehicles carry their own preventive maintenance requirements, and their inspection completion rolls into the same overall PM compliance calculation as the rest of the fleet.
How far back does FleetRabbit keep compliance rate history
Inspection records and calculated compliance rates are stored continuously in the platform, so a full history is available for export whenever a Triennial Review or internal audit requires it.
