Breakdown of Maintenance Costs by Vehicle System (continued)
Tire Repairs (ATA VMRS 17) Parts Cost Labor Hours Average Labor Cost Total Cost (for system) Total Cost (for system) per Bus Total Cost (for system) per Mile
Notes 1. The engine/fuel-related systems were chosen to include only those systems of the vehicles that could be directly impacted by the selection of a fuel.
2. ATA VMRS coding is based on parts that were replaced. If there was no part replaced in a given repair, the code was chosen by the system being worked on.
3. In general, inspections (with no part replacements) were only included in the overall totals (not by system). 101 was created to track labor costs for PM inspections.
4. ATA VMRS 02-cab and sheet metal represents seats, doors, etc. ATA VMRS 50-accessories represents things like fire extinguishers, test kits, etc. ATA VMRS 71-body represents mostly windows and windshields.
Average labor cost is assumed to be $50 per hour.
Warranty costs are not included.
