NOVA BUS Download PDF Report
Nova Bus a Division of Prevost Car (U.S.) Inc., submitted a model 82 VW, LNG-fueled, 43 seat/40-foot bus, for a partial STURAA test in the 12 yr/500,000 mile category. This partial test is a supplement to original report PTI-BT-R9921-11-01. The Federal Transit Administration determined that the following test would be performed; 5.7 Structural Durability Test. The odometer reading at the time of delivery was 35.0 miles. Testing started on January 15, 2002 and was completed on June 3, 2002. The Check-In section of the report provides a description of the bus and specifies its major components.
The primary part of this partial test was the Structural Durability Test, which also provides the information for the Reliability results. The Structural Durability Test was started on January 16, 2002 and was completed on May 30, 2002.
The interior of the bus is configured with seating for 43 passengers including the driver. Free floor space will accommodate 28 standing passengers resulting in a potential capacity of 71 persons. At 150 lbs per person, this load results in a measured gross vehicle weight of 38,550 lbs. The first segment of the Structural Durability Test was performed with the bus loaded to a GVW of 38,550 lbs. The middle segment was performed at a seated load weight of 34,150 lbs and the final segment was performed at a curb weight of 27,990 lbs. Durability driving resulted in unscheduled maintenance and failures that involved a variety of subsystems. A description of failures, and a complete and detailed listing of scheduled and unscheduled maintenance is provided in the Maintainability section of this report.
The Reliability section compiles failures that occurred during Structural Durability Testing. Breakdowns are classified according to subsystems. The data in this section are arranged so that those subsystems with more frequent problems are apparent. The problems are also listed by class as defined in Section 2. The test bus encountered no Class 1 or Class 2 failures. Of the fourteen reported failures, eleven were Class 3 and three were Class 4.
