CHAMPION BUS INC. Download PDF Report
Champion Bus Inc. submitted a model Crusader/American Crusader, gasoline-powered 10 seat (including the driver) 23-foot bus, for a partial STURAA test in the
7 yr/200,000 mile category. The odometer reading at the time of delivery was 506 miles. Testing started on January 19, 2009 and was completed on March 25, 2009. 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 Maintainability and Reliability results. The Structural Durability Test was started on January 29, 2009 and was completed on March 20, 2009.
The interior of the bus is configured with seating for 10 passengers including the driver plus 1 wheelchair position. Free floor space will accommodate 7 standing passengers resulting in a potential load of 17 persons plus 1 wheelchair position. At 150 lbs per person, this load results in a measured gross vehicle weight of 11,940 lbs. The first segment of the Structural Durability Test was performed with the bus loaded to a GVW of 11,940 lbs. The middle segment was performed at a seated load weight of 10,960 lbs and the final segment was performed at a curb weight of 8,890 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 4 reported failures, 2 were Class 3 and 2 were Class 4.
The Safety Test, (a double-lane change, obstacle avoidance test) was safely performed in both right-hand and left-hand directions up to a maximum test speed of 45 mph.
