CHAMPION BUS INC. Download PDF Report
Champion Bus, Inc. submitted a model CTS, diesel powered 26 seat/33-foot bus, for a Partial STURAA test in the 7 year/200,000 mile category. The Federal Transit Administration determined that the following tests would be performed: 1.2 Servicing, Preventative Maintenance, and Repair and Maintenance During Testing, 2. Reliability and 5.7 Structural Durability Test. The odometer reading at the time of delivery was 1,308 miles. Testing started on August 29, 2000 and was completed on November 30, 2000. The Check-In Section of the report provides a description of the bus and specifies its major components.
The primary part of this test was Structural Durability Test, which also provides the information for the maintainability and reliability results. The Structural Durability Test was started on August 30, 2000 and was completed on November 29, 2000.
The first segment of the structural durability test was performed with the bus loaded to a GVW of 22,450 lbs. The middle segment was performed at a SLW of 19,550 lbs and the final segment was performed at a CW of 14,500 lbs. Durability driving resulted in unscheduled maintenance that consisted of a variety of subsystem failures. These failures can be found in a complete and detailed listing of scheduled and unscheduled maintenance, which 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. Also the problems also are listed by class as defined in section 2. The test bus encountered no Class 1 or Class 2 failures. Of the eighteen reported failures, twelve were Class 3 and six were Class 4.
